Abstract

For producing loose inserts (30) for envelopes, in the regions, in which the inserts (30), corresponding to the positional layout of the envelopes, are to have a distance from one another in production, there are made between neighbouring inserts (30) double cuts in the form of longitudinal cuts (25, 26) and/or in the form of transverse cuts (27, 28, 29) and thus cutoff parts (31) are cut free. The front transverse sections (39) in conveying direction (arrow 20) of the cutoff parts (31) are lifted out of the web (21) at the time of their cutting free and, after subsequent cutting free of the rear end of the cutoff part (31), drawn off. As a result, loose inserts for envelopes can be manufactured multiply lying next to one another and thus positionally accurately with high speed in such a manner that they can be transferred immediately subsequently between the cover layers of the envelopes. <IMAGE>

Description

Die Erfindung betrifft eine Vorrichtung, die zur Herstellung von Einlagen für Versandhüllen bzw. von Versandhüllen geeignet sein soll, welche solche Einlagen enthalten, wobei die Einlage jeder Versandhülle eine, zwei oder mehrere aufeinanderliegende Lagen aufweisen kann, von den gebenenfalls mindestens zwei ohne Faltverbindung lose übereinander liegen.The invention relates to a device which is intended to be suitable for the production of inlays for shipping envelopes or of shipping envelopes which contain such inlays, the inlays of each shipping envelope having one, two or more layers lying one on top of the other, at least two of which optionally loosely one above the other without a folded connection lie.

Damit die Einlagen im Durchlauf mit hoher Arbeitsgeschwindigkeit genau hergestellt werden können, weist die Vorrichtung zweckmäßig eine Transportstrecke für eine oder mehrere Einlage-Bahnen, z.B. Papierbahnen, auf, wobei entlang der Transportstrecke die Einlagen ein- oder mehrlagig aus den Bahnen herausgetrennt werden. Für dieses Heraustrennen sind Trennmittel, wie Schneideinrichtungen mit Schneidmessern, vorgesehen.In order that the inserts can be produced precisely in one pass at high working speed, the device expediently has a transport path for one or more insert webs, for example paper webs, the inserts being made of one or more layers along the transport path the webs are cut out. Separating means, such as cutting devices with cutting knives, are provided for this separation.

Werden die Einlagen nur hintereinanderliegend aus den Bahnen herausgetrennt, so ist die Arbeitsgeschwindigkeit durch die maximale Laufgeschwindigkeit der Bahnen, der Trennmittel, von Klebstoff-Auftrageinrichtungen, Querperforier-Einrichtungen oder dgl. begrenzt, ohne daß die Möglichkeit besteht, den Ausstoß der Vorrichtung an fertiggestellten Versandhüllen wesentlich zu erhöhen.If the inserts are separated from the webs only one behind the other, the working speed is limited by the maximum running speed of the webs, the separating means, adhesive application devices, cross-perforating devices or the like, without the possibility of the device being ejected from finished shipping envelopes to increase significantly.

Nach der US-A-3 255 679 ist eine Vorrichtung bekannt, bei welcher zunächst alle Materialbahnen einschließlich derjenigen für die Einlage-Lagen zusammengeführt und dann erst die Einlage-Lagen herausgetrennt werden. Die US-A-4 306 475 betrifft eine Stanzvorrichtung für Asphaltschindeln, die nach dem Heraustrennen nicht mit einer Trägerlage zusammengeführt werden.According to US Pat. No. 3,255,679, a device is known in which all the material webs, including those for the insert layers, are first brought together and only then are the insert layers separated. US-A-4 306 475 relates to a punching device for asphalt shingles which, after being separated, are not brought together with a carrier layer.

Der Erfindung liegt des weiteren die Aufgabe zugrunde, Nachteile bekannter Vorrichtungen der genannten Art zu vermeiden, insbesondere eine Vorrichtung zur Herstellung von Einlagen bzw. Versandhüllen zu schaffen, bei welcher auf einfache Weise ein wesentlich erhöhter Ausstoß an Einlagen bzw. Versandhüllen erreicht werden kann.The invention is also based on the object of avoiding disadvantages of known devices of the type mentioned, in particular to provide a device for producing inserts or shipping envelopes in which a significantly increased output of inserts or shipping envelopes can be achieved in a simple manner.

Diese Aufgabe kann durch die Merkmale des Anspruches 1 gelöst werden. Zweckmäßig sind Mittel vorgesehen, um wenigstens einen Teil der Einlagen oder Versandhüllen seitlich gegeneinander versetzt bzw. seitlich benachbart zueinander herzustellen. Erfolgt die Herstellung mindestens einer oder aller Lagen der jeweils seitlich benachbart hergestellten Einlagen und/oder der Decklagen der Versandhülle jeweils aus derselben Bahn, so ergibt sich eine zwei-, drei- oder mehrnutzige Herstellung, die bei gleicher Laufgeschwindigkeit entsprechend zu einem mehrfachen Ausstoß führt.This object can be achieved by the features of claim 1. Means are expediently provided in order to produce at least some of the inserts or shipping envelopes laterally offset from one another or laterally adjacent to one another. If at least one or all of the layers of the inserts produced laterally adjacent and / or the cover layers of the shipping envelope are produced from the same Bahn, so there is a two-, three- or multi-use production, which leads to a multiple output at the same running speed.

Die erfindungsgemäße Ausbildung ist insbesondere für solche Versandhüllen, nämlich sogenannte Mailer-Formulare bestimmt, bei welchen mindestens ein seitlicher, etwa in Längsrichtung der zugehörigen Bahn liegender Rand der Einlage gegenüber dem zugehörigen Rand der Versandhülle oder von deren Decklagen zurückversetzt bzw. nicht unmittelbar an diesen Decklagen befestigt ist. Derartige Einlagen sind besonders einfach aus der Versandhülle zu entnehmen und können vollständig lose zwischen den am Rand miteinander verbundenen Decklagen der Versandhülle eingelegt sein, so daß sie gegenüber allen Außenkanten bzw. Haftverbindungen der Decklagen der Versandhülle zurückversetzt sind. Bei der mehrnutzigen Herstellung ergibt sich hier die Schwierigkeit, daß die Decklagen und die Einlagen seitlich benachbart in der Herstellung befindlicher Versandhüllen an ihren einander zugekehrten Seiten nicht gemeinsam beschnitten werden können.The training according to the invention is particular intended for such shipping envelopes, namely so-called mailer forms, in which at least one lateral edge of the insert, approximately in the longitudinal direction of the associated web, is set back relative to the associated edge of the shipping envelope or its cover layers or is not directly attached to these cover layers. Such inserts are particularly easy to remove from the shipping envelope and can be inserted completely loosely between the cover layers of the shipping envelope connected to one another at the edge, so that they are set back against all outer edges or adhesive connections of the cover layers of the shipping envelope. In the case of multi-use production, the difficulty arises here that the cover layers and the inserts laterally adjacent in the production of shipping envelopes cannot be trimmed together on their mutually facing sides.

Um einen seitlichen Abstand zwischen mindestens zwei Lagen seitlich benachbart zueinander hergestellter Einlagen zu erzielen, sind Distanziermittel vorgesehen, durch welche diese Lagen bzw. Einlagen vor dem Zwischenlegen zwischen die Decklagen der Versandhülle den erforderlichen Abstand erhalten. Es ist zwar denkbar, die seitlich benachbarten Lagen der Einlagen durch einen einzigen Trenn- bzw. Längsschnitt voneinander zu trennen und darauffolgend auf den genannten Seitenabstand auseinander zu fahren, jedoch ist hierfür ein verhältnismäßig großer Aufwand und gegebenenfalls eine erhöhte Belastung der Bahnen erforderlich.In order to achieve a lateral distance between at least two layers of inserts made laterally adjacent to one another, spacing means are provided, by means of which these layers or inserts receive the required distance before the interposition between the cover layers of the shipping envelope. Although it is conceivable to separate the laterally adjacent layers of the inserts from one another by means of a single separating or longitudinal section and then to move them apart to the mentioned lateral distance, this requires a relatively large outlay and possibly an increased load on the webs.

Daher wird gemäß der Erfindung des weiteren vorgeschlagen, die Distanziermittel dadurch zu bilden, daß die Trennmittel einen seitlichen Abstandschnitt herstellen, nämlich aus der jeweiligen Bahn zwischen den benachbarten Lagen einen Abtrennteil herauszutrennen. Dieser entspricht in Form und Breite genau dem Abstand, den diese Lagen bei der Herstellung seitlich benachbarter Versandhüllen einnehmen, nämlich dann, wenn die seitlich benachbarten Einlagen zwischen die Decklagen seitlich benachbart hergestellter Versandhüllen engelegt werden. Die Decklagen der seitlich benachbart hergestellten Versandhüllen und damit diese selbst können dann durch einen einzigen Trennschnitt voneinander getrennt werden.Therefore, according to the invention further proposed to form the spacing means in that the separating means produce a lateral spacing cut, namely to separate a separating part from the respective web between the adjacent layers. In terms of shape and width, this corresponds exactly to the distance these layers occupy in the production of laterally adjacent shipping envelopes, namely when the laterally adjacent inserts are placed between the cover layers of shipping envelopes produced laterally adjacent. The cover layers of the shipping sleeves produced next to one another and thus these themselves can then be separated from one another by a single separating cut.

Sollen mindestens einzelne Lagen der hintereinander hergestellten Einlagen auch in Längsrichtung der Bahnen gegenüber den Außenrändern bzw. Haftverbindungen der zugehörigen Versandhüllen an mindestens einem Rand zurückversetzt sein, so müssen sie beim Einlegen zwischen die Decklagen durch geeignete Distanziermittel einen entsprechenden Längsabstand voneinander haben; diese Längs-Distanziermittel können statt der oder zusätzlich zu den oben beschriebenen Quer-Distanziermitteln bzw. zur zwei- oder mehrnutzigen Herstellung vorgesehen sein. Die Längs-Distanziermittel können durch eine geeignete Beschleunigungstrecke gebildet sein, in welcher die jeweils in Transportrichtung vordere Lage nach ihrer Quertrennung von der Bahn gegenüber dieser so beschleunigt wird, daß der geforderte Abstand erreicht wird. Besonders vorteilhaft ist es jedoch, wenn die Quer-Distanziermittel durch Mittel gebildet werden, mit welchen zwischen den aufeinanderfolgenden Lagen ein Abtrennteil herausgetrennt wird, dessen Breite und Form in der beschriebenen Weise dem Abstand zwischen hintereinanderliegenden Einlagen vor Trennung der hintereinanderliegend hergestellten Versandhüllen entspricht.If at least individual layers of the inlays produced one behind the other are to be set back on at least one edge in the longitudinal direction of the webs in relation to the outer edges or adhesive connections of the associated shipping envelopes, they must have a corresponding longitudinal distance from one another by means of suitable spacers when inserting between the cover layers; these longitudinal spacing means can be provided instead of or in addition to the above-described transverse spacing means or for two- or multi-use production. The longitudinal spacing means can be formed by a suitable acceleration path, in which the respective front position in the transport direction is accelerated after its transverse separation from the web in such a way that the required distance is achieved. However, it is particularly advantageous if the transverse spacing means are formed by means with which a separating part is separated out between the successive layers whose width and shape corresponds in the manner described to the distance between successive inserts before separation of the shipping casings produced one behind the other.

Die genannten Distanzmittel können auch so ausgebildet sein, daß der herausgetrennte Abtrennteil in Breite und Form kleiner als der genannte Abstand ist, so daß benachbarte Einlagen zur Erzielung der geforderten Abstandslage nicht um das vollständig Abstandsmaß, sondern nur um einen Teil davon auseinandergefahren werden müssen. Besonders vorteilhaft ist es, wenn die Trennmittel so ausgebildet sind, daß sie jeweils mindestens einen querliegenden Abtrennteil und mindestens einen längsliegenden Abtrennteil einteilig zusammenhängend heraustrennen, so daß dieser zusammenhängende Abtrennteil dann z.B. als Abfall leicht quer aus der Bahn herausbewegt und entfernt werden kann. Zweckmäßig wird dieser Abtrennteil auf einer in Laufrichtung der Materialbahn zunehmend ansteigenden und tangential an die Materialbahn anschließenden Bogenbahn von der Materialbahn entfernt; dadurch ergibt sich eine sehr sichere und störungsfreie Ablösung des Abtrennteiles.The distance means mentioned can also be designed so that the separated part is smaller in width and shape than the distance mentioned, so that adjacent inserts do not have to be moved apart by the complete distance dimension to achieve the required distance position, but only by a part thereof. It is particularly advantageous if the separating means are designed such that they each separate at least one transverse separating part and at least one longitudinal separating part in one piece, so that this connected separating part then e.g. can be easily moved as waste out of the web and removed. This separating part is expediently removed from the material web on an arc web that increases increasingly in the running direction of the material web and tangentially adjoins the material web; this results in a very safe and trouble-free detachment of the separating part.

Die Trennmittel sind zweckmäßig so ausgebildet, daß quer zueinander liegende Schnitte, die dann quer zueinander liegende Außenkanten des Abtrennteils begrenzen, sich mit ihren einander zugekehrten Enden um ein geringes Maß kreuzen, so daß der jeweilige Schnitt geringfügig in den quer zu ihn liegenden Abschnitt des Abtrennteiles hineinreicht. Dadurch ist ein völlicher Freischnitt des Abtrennteiles auf jeden Fall gewährleistet.The separating means are expediently designed in such a way that cuts lying transversely to one another, which then delimit transversely lying outer edges of the separating part, intersect by a small amount with their mutually facing ends, so that the respective cut is slightly into the section of the separating part lying transversely to it reaches in. This ensures that the separating part is completely cut free.

Bei einer bevorzugten Ausführungsform werden zuerst die paarweisen Längsschnitte zwischen benachbart herzustellenden Einlagen hergestellt, wobei jedes Paar von Längsschnitten gegenüber dem darauffolgenden Paar einen Längsabstand von z.B 9 bis 10 mm hat, der geringfügig kleiner ist als der erforderliche Abstand zwischen hintereinander hergestellten Einlagen; dieser Abstand kann z.B 10 bis 20 mm betragen. Unmittelbar nach dem Herstellen der formathaltigen Längsschnitte bzw. Längsperforationen mit Längsschneidemessern, die Schnittunterbrechungen aufweisen können, werden paarweise Querschnitte unmittelbar aufeinanderfolgend zweckmäßig mit einem rotierenden Schneidwerkzeug hergestellt, das ein oder mehrere über seinen Umfang verteilte Paare von Querschneidmessern aufweist. Um voneinander zu trennende Teile der jeweiligen Bahn nach dem jeweiligen Schnitt, insbesondere dem Längsschnitt, noch wenigstens auf einem anschließenden Teil des weiteren Laufweges gegeneinander in der Lage zu sichern, kann dieser Schnitt zunächst mit mindestens einer im Abstand von seinen vorbestimmten Enden liegenden Unterbrechung ausgeführt werden. Die jeweilige Unterbrechung bildet dann nach Art einer Perforation eine Solltrenn-Verbindung zwischen den genannten Teilen und kann an jeder gewünschten Stelle der weiteren Transportstrecke, insbesondere beim Herauslösen des Abtrennteiles durch Reißen oder Schneiden durchtrennt werden.In a preferred embodiment, the pairwise longitudinal cuts are first made between adjacent inserts, each pair of longitudinal cuts being a longitudinal distance of, for example, 9 to 10 mm from the subsequent pair, which is slightly smaller than the required distance between successively made inserts; this distance can be e.g. 10 to 20 mm. Immediately after making the longitudinal cuts or longitudinal perforations with longitudinal cutters, which may have interruptions in cut, pairs of cross-sections are expediently produced in immediate succession using a rotating cutting tool which has one or more pairs of transverse cutting knives distributed over its circumference. In order to secure parts of the respective web which are to be separated from one another after the respective cut, in particular the longitudinal cut, at least on a subsequent part of the further travel path, this cut can first be carried out with at least one interruption spaced from its predetermined ends . The respective interruption then forms, in the manner of a perforation, a predetermined separation connection between the parts mentioned and can be severed by tearing or cutting at any desired point on the further transport route, in particular when the separation part is removed.

Das aufgrund der Drehbewegung zuerst in Eingriff gelangende Schneidmesser des jeweiligen Paares führt einen über zwei oder mehr seitlich benachbarte Einlagen im wesentlichen ununterbrochen durchgehenden Querschnitt aus, während das darauffolgende Schneidmesser einen Querschnitt ausführt, der zwischen den Längsschnitten mindestens eines Längsschnitt-Paares unterbrochen ist. Dadurch ist der Abtrennteil bis auf sein in Laufrichtung hinteres Ende vollständig von der Bahn freigeschnitten. Beim darauffolgenden Querschnitt wird auch dieses Ende freigeschnitten und dadurch abgetrennt. Zweckmäßig wird der Abtrennteil bereits vor dem vollständigen Trennen seines hinteren Endes in der beschriebenen Weise, z.B. nach oben, mit seinem vorderen Ende aus der Bahn herausbewegt, so daß er praktisch im Augenblick des Abtrennens seines hinteren Endes vollständig aus der Bahn herausbewegt ist. Z.B. können zwischen den Einzelmessern jedes Querschneid-Messerpaares Haftmittel, wie Ansaugöffnungen vorgesehen sein, mit welchen das in Laufrichtung vordere Ende des Abtrennteiles gegenüber dem Querschneid-Werkzeug im Augenblick der Durchführung des Querschnittes festgelegt wird, so daß der Abtrennteil praktisch nur durch Zugbelastung aus der Bahn herausbewegt wird. Auf einer außerhalb der Schneidzone liegenden Teilstrecke der Bewegungsbahn der Querschneidmesser wird der Abtrennteil an eine Abführung übergeben, die z.B. durch einen Absaugkanal gebildet sein kann.The cutting knife of the respective pair, which first comes into engagement due to the rotary movement, leads essentially continuously over two or more laterally adjacent inserts continuous cross section, while the subsequent cutting knife executes a cross section which is interrupted between the longitudinal cuts of at least one pair of longitudinal cuts. As a result, the separating part is completely cut free of the web except for its rear end in the running direction. In the subsequent cross section, this end is also cut free and cut off. Advantageously, the separating part is moved out of the web with its front end before the complete separation of its rear end in the manner described, for example upwards, so that it is practically completely moved out of the web at the moment when its rear end is separated. For example, adhesive, such as suction openings, can be provided between the individual knives of each pair of cross-cutting knives, with which the front end of the separating part in the direction of travel is fixed relative to the cross-cutting tool at the time the cross-section is carried out, so that the separating part is practically only by tensile load from the web is moved out. On a section of the movement path of the cross-cutting knives lying outside the cutting zone, the separating part is transferred to a discharge which can be formed, for example, by a suction channel.

Zur genauen Ausrichtung und Führung mindestens einer Einlage-Bahn sind für diese Führungsmittel vorgesehen, die zweckmäßig in mindestens einen Längsrand der Bahn im wesentlichen formschlüssig eingreifen. Z.B. kann die Bahn am Längsrand einen Lochrand, wie einen sogenannten Remaliner-Lochrand mit hintereinander liegenden Löchern für den Eingriff von Führungs-und/oder Transportstiften aufweisen. Vorteilhaft sind Mittel vorgesehen, um diesen Lochrand vor Durchführung des jeweiligen Querschnittes und/oder vor Durchführung des jeweiligen Längsschnittes abzutrennen und von der zugehörigen Bahn wegzuführen. Vorrichtungen der beschriebenen Art bilden zweckmäßig im Bereich einer Längsseite die Antriebsseite, an welcher die Antriebe bzw. Antriebsverbindungen für die angetriebenen Maschinenteile, wie Messer, Förderer oder dgl. vorgesehen sind; die gegenüberliegende Längsseite bildet die Bedienseite, die von solchen Antriebsverbindungen im wesentlichen frei ist. Vorteilhaft wird der Lochrand der Bahn wenigstens auf der Antriebsseite oder auf beiden Längsseiten erst unmittelbar vor der Quertrenneinrichtung, insbesondere zwischen dieser und der Führungseinrichtung abgetrennt, so daß die Bahn bis unmittelbar an die Quertrenneinrichtung geführt werden kann. Der der Bedienseite zugehörige Lochrand kann auch an einer demgegenüber weiter hinten liegenden Stelle bereits abgetrennt werden, z.B. unmittelbar vor oder nach der Längstrenneinrichtung bzw. vor dem vorderen Ende der auf diese folgenden Führungseinrichtung.For precise alignment and guidance of at least one insert web are provided for these guiding means, which expediently engage in a substantially form-fitting manner in at least one longitudinal edge of the web. For example, the web can have a perforated edge on the longitudinal edge, such as a so-called Remaliner perforated edge with holes one behind the other for the engagement of guide and / or transport pins exhibit. Means are advantageously provided in order to separate this hole edge before carrying out the respective cross section and / or before carrying out the respective longitudinal section and to lead it away from the associated path. Devices of the type described expediently form the drive side in the region of a longitudinal side, on which the drives or drive connections for the driven machine parts, such as knives, conveyors or the like, are provided; the opposite long side forms the operating side, which is essentially free of such drive connections. The hole edge of the web is advantageously separated at least on the drive side or on both longitudinal sides only immediately in front of the cross-cutting device, in particular between the latter and the guide device, so that the web can be guided directly to the cross-cutting device. The edge of the hole belonging to the operating side can also already be cut off at a point further back, for example immediately before or after the longitudinal cutting device or in front of the front end of the guiding device following this.

Die Erzeugung des Abstandes zwischen benachbarten Einlagen hat dadurch, daß zwischen diesen ein Abtrennteil herausgetrennt wird, auch den wesentlichen Vorteil, daß unmittelbare Verbindungen zwischen aufeinander liegenden Einlage-Bahnen wenigstens teilweise oder ausschließlich in den Bereichen vorgesehen werden können, die als Abtrennteile herausgetrennt werden. Derartige Verbindungen dienen zu gegenseitigen Lagesicherung der Bahnen insbesondere während den Schnitten und werden daher, z.B. als Crimpverbindungen, vor Durchführung der Schnitte hergestellt. Erfindungsgemäß sind insofern, insbesondere bei einer Vorrichtung der beschriebenen Art, Mittel zur gegenseitigen Lagesicherung aufeinanderliegender Bahnen vorgesehen, wobei diese Mittel im wesentlichen ausschließlich in solchen Bereichen an den Bahnen angreifen, die außerhalb der herauszutrennenden Einlage-Lagen und zwischen deren Längskanten liegen.The generation of the distance between adjacent inserts by the fact that a separating part is separated between them also has the essential advantage that direct connections between superimposed insert sheets can be provided at least partially or exclusively in the areas which are separated out as separating parts. Such connections serve to secure the position of the webs in particular during the cuts and are therefore used, for example, as crimp connections Execution of the cuts made. According to the invention, in particular in the case of a device of the type described, means are provided for mutually securing the position of webs lying one on top of the other, these means essentially only attacking the webs in those areas which lie outside the insert layers to be removed and between their longitudinal edges.

Die erfindungsgemäße Vorrichtung ist zweckmäßig unmittelbar einer Vorrichtung vorgeschaltet, in welcher die Einlagen auf eine untere Materialbahn aufgelegt und mit einer oberen Materialbahn abgedeckt werden, wobei diese beiden Materialbahnen die Decklagen der Versandhüllen bilden. Aus diesen Materialbahnen mit zwischengelegten Einlagen werden dann die fertigen Versandhüllen in der Nutzenzahl herausgetrennt, die der Nutzenzahl bei der Herstellung der Einlagen entspricht. Der Abstand zwischen den Einlagen benachbart hergestellter Versandhüllen und damit der Abstand jeder Einlage gegenüber den Außenkanten der zugehörigen Versandhülle ist dadurch vom Freischneiden der jeweiligen Einlage bis zu deren Einschluß in die Decklagen der Versandhülle gesichert, ohne daß die Einlage-Lagen oder die Decklagen eine seitliche Querbewegung ausführen müssen.The device according to the invention is expediently connected directly to a device in which the inserts are placed on a lower material web and covered with an upper material web, these two material webs forming the cover layers of the shipping envelopes. The finished shipping envelopes are then separated from these material webs with interleaved inserts in the number of blanks corresponding to the number of blanks in the production of the inserts. The distance between the inserts of adjacent shipping envelopes and thus the distance of each insert from the outer edges of the associated shipping envelope is secured from cutting the respective insert to its inclusion in the cover layers of the shipping envelope, without the insert layers or the cover layers having a lateral transverse movement have to perform.

Die Erfindung betrifft auch das beschriebene Verfahren, die beschriebenen, fertigen Versandhüllen und als Halbfertigerzeugnis die einlagige oder mehrlagige Materialbahn in demjenigen Zustand, den sie durch Einbringen der jeweiligen Schnitte bzw. der Bahnverbindungen hat.The invention also relates to the method described, the finished shipping envelopes described and, as a semi-finished product, the single-layer or multi-layer material web in the state in which it is made by making the respective cuts or the web connections.

Diese und weitere Merkmale von bevorzugten Weiterbildungen der Erfindung gehen aus der Beschreibung und den Zeichnungen hervor, wobei die einzelnen Merkmale jeweils für sich allein oder zu mehreren in Form von Unterkombinationen bei einer Ausführungsform der Erfindung und auf anderen Gebieten verwirklicht sein und vorteilhafte sowie für sich schutzfähige Ausführungen darstellen können, für die hier Schutz beansprucht wird. Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im Folgenden näher erläutert. In den Zeichnungen zeigen:

These and further features of preferred developments of the invention are evident from the description and the drawings, the individual features being realized individually or in groups in the form of sub-combinations in one embodiment of the invention and in other fields, and being advantageous and protectable per se Can represent versions for which protection is claimed here. An embodiment of the invention is shown in the drawings and is explained in more detail below. The drawings show:

Gemäß den Figuren 1 bis 3 werden mit einer erfindungsgemäßen Vorrichtung 1 mindestens eine, zwei oder mehrere Einlage-Bahnen 3,4 von Speichern 5, 6, z.B. von Papierrollen, über Umlenkungen etwa horizontal zugeführt, wobei aus den Bahnen 3,4 die Einlagen hergestellt werden. Am Ausgang der Vorrichtung 1 werden die jeweils über den gesamten Kanten-Umfang freigeschnittenen Einlagen dann auf eine von einem weiteren Speicher 9 abgezogene Träger-Bahn 7 gelegt und unmittelbar darauffolgend mit einer von einem Speicher 10 abgezogenen Deck-Bahn 8 abgedeckt. Die zweilagige Bahn mit zwischenliegenden Einlagen wird dann einer Vorrichtung 2 zu Fertigstellung der Versandhüllen zugeführt, in welcher die Versandhüllen aus den Bahnen 7,8 abgetrennt werden, so daß einzelne Versandhüllen nach Art gefüllter Briefumschläge erzeugt sind. Anstatt die Versandhüllen vollständig abzuschneiden, können auch Trennperforationen zwischen seitlich und/oder hintereinander benachbarten Versandhüllen vorgesehen werden, so daß diese als ein-oder mehrnutziges, zickzackförmig gefaltetes Band weiterverarbeitet, z.B. adressiert und dann erst vollständig voneinander getrennt werden können.According to FIGS. 1 to 3, with a device 1 according to the invention, at least one, two or more insert webs 3, 4 of stores 5, 6, for example of paper rolls, are fed approximately horizontally via deflections, the inserts being produced from the webs 3, 4 will. At the exit of the device 1, the inserts cut free over the entire circumference of the edge are then placed on a carrier web 7 drawn off from a further store 9 and immediately thereafter with a cover web pulled off from a store 10 8 covered. The two-ply web with intermediate inserts is then fed to a device 2 for completing the mailing envelopes, in which the mailing envelopes are separated from the webs 7, 8, so that individual mailing envelopes are produced in the manner of filled envelopes. Instead of completely cutting off the shipping envelopes, separating perforations can also be provided between adjacent and / or consecutive shipping envelopes, so that they can be further processed as a single-use or multiple-use, zigzag folded tape, for example addressed and only then separated completely.

Die Träger-Bahn 7 wird unterhalb der Transportstrecke 11 der Vorrichtung 1 um die bzw. unter den Bahnen 3,4 herumgeführt, während die Deck-Bahn 8 unmittelbar von oben der Transportstrecke 3 zugeführt wird.The carrier web 7 is guided around the or below the webs 3, 4 below the transport path 11 of the device 1, while the cover web 8 is fed directly to the transport path 3 from above.

Im Bereich der im wesentlichen horizontalen Transportstrecke 11 der Vorrichtung 1 ist eine aus mehreren aufeinanderfolgenden Einheiten bestehende Trenneinrichtung 12 vorgesehen, die eine Längstrenneinrichtung 13 und auf diese folgend eine Quertrenneinrichtung 14 aufweist. Unmittelbar vor der Längstrenneinrichtung 13 ist eine Crimpeinrichtung zur im wesentlichen formschlüssigen unmittelbaren Verbindung der beiden Bahnen 3,4 vorgesehen. Vor und/oder nach der Längstrenneinrichtung 13 ist für die jeweiligen, deckungsgleichen Längsränder der gleich breiten Bahnen 3,4 eine Führungseinrichtung 16 vorgesehen. Diese Längsränder werden unmittelbar vor der Quertrenneinrichtung 14 oder unmittelbar nach der Längstrenneinrichtung 13 mit Abtrenneinrichtung 17,18 getrennt und abgeführt. Unmittelbar nach der Trenneinrichtung 12 bzw. der Quertrenneinrichtung 14 ist eine Fördereinrichtung 19 für die freigeschnittenen und allseits im Abstand zueinander liegenden Einlagen vorgesehen, welche die Einlagen in Förderrichtung Pfeil 20 unmittelbar auf die Träger-Bahn 7 abgibt.In the area of the essentially horizontal transport path 11 of the device 1, a separating device 12 consisting of several successive units is provided, which has a longitudinal separating device 13 and, following this, a transverse separating device 14. Immediately in front of the longitudinal separating device 13, a crimping device is provided for the essentially form-fitting direct connection of the two tracks 3, 4. Before and / or after the longitudinal separating device 13, a guide device 16 is provided for the respective congruent longitudinal edges of the webs 3, 4 of the same width. These longitudinal edges are immediately in front of the cross cutting device 14 or immediately after the longitudinal cutting device 13 with separating device 17, 18 separated and discharged. Immediately after the separating device 12 or the transverse separating device 14, a conveying device 19 is provided for the cut-out inserts, which are spaced apart on all sides, which delivers the inserts in the conveying direction arrow 20 directly onto the carrier web 7.

In Fig. 1 ist die einlagige oder aus zwei bzw. mehr Bahnen 3,4 bestehende Gesamt-Bahn 21 dargestellt, deren Längsrand 22 auf der Antriebsseite und deren gegenüberliegender Längsrand 23 auf der Bedienseite der Vorrichtung liegt. Beide Längsränder 22,23 sind jeweils mit einer Längs-Lochung 24 versehen, in welche die zugehörige Führungseinrichtung 16, z.B. ein Stiftband, eingreift. Die Gesamtbahn 21 wird mit gleichmäßiger Geschwindigkeit in Förderrichtung Pfeil 20 etwa horizontal bzw. in ihrer Längsrichtung durch die Vorrichtung 1 bewegt, wobei während dieses Durchlaufes mit rotierenden Werkzeugen abgesetzte Längsschnitte 25 und Querschnitte 27,28,29 hergestellt werden. Dadurch werden gleichzeitig jeweils zwei oder mehr mit geringem Abstand nebeneinander liegende Einlagen 30 gleichzeitig und in geringem Abstand hintereinander liegende Einlagen 30 unmittelbar aufeinanderfolgend hergestellt. Im dargestellten Ausführungsbeispiel sind die Einlagen 30 rechteckig bzw. annähernd quadratisch begrenzt, sie können aber auch unregelmäßige Form bzw. Kanten haben.In Fig. 1 the single-layer or consisting of two or more webs 3, 4 total web 21 is shown, the longitudinal edge 22 of which is on the drive side and the opposite longitudinal edge 23 of which is on the operating side of the device. Both longitudinal edges 22, 23 are each provided with a longitudinal perforation 24 into which the associated guide device 16, e.g. a pen tape, engages. The entire web 21 is moved at a uniform speed in the conveying direction arrow 20 approximately horizontally or in its longitudinal direction by the device 1, longitudinal cuts 25 and cross sections 27, 28, 29 being made using rotating tools during this pass. As a result, two or more inserts 30 lying next to one another with a small spacing are simultaneously produced simultaneously and inserts 30 lying one behind the other at a short distance immediately in succession. In the exemplary embodiment shown, the inserts 30 are limited to be rectangular or approximately square, but they can also have an irregular shape or edges.

Zur Herstellung des seitlichen und des Längsabstandes wird jeweils zwischen seitlich benachbarten Einlagen 30 und anschließend an deren in Förderrichtung Pfeil 20 vordere Kanten ein einteiliger Abtrennteil 31 herausgeschnitten, der dann einen von den vorderen Kanten mindestens zweier nebeneinander liegender Einlagen 30 abzulösenden Querabschnitt 33 und mindestens einen an dessen hintere Kante anschließenden Längsabschnitt 32 aufweist. Dieser Längsabschnitt 32, der vor dem Querabschnitt 33 freigeschnitten wird, ist nach dem Freischnitt des Querabschnittes 33 mit seinem hinteren Ende noch einteilig mit der Gesamt-Bahn 21 verbunden und wird mit dem darauffolgenden Querschnitt 27 für die nächstfolgenden Einlagen 30 abgetrennt, wobei er im Augenblick dieser Abtrennung bereits im wesentlichen vollständig aus der Gesamt-Bahn 21 herausgehoben ist. Die einzelnen Lagen des jeweiligen Abtrennteiles 31 sind über Crimpungen 34 miteinander verbunden, die im wesentlichen gleichmäßig über die Breite der Gesamt-Bahn 21 verteilt und ausschließlich im Bereich des jeweiligen Querabschnittes 33 vorgesehen sind. Unmittelbar vor der Quertrenneinrichtung 14 wird der Längsrand 22 mit einem Trennschnitt 35 abgetrennt. Der andere Längsrand 23 kann mit einem Trennschnitt 36 ebenfalls in diesem Bereich oder davor, zweckmäßig jedoch nach Herstellung der Crimpungen 34 bzw. der Längsschnitte 25,26 abgetrennt werden.To produce the lateral and the longitudinal spacing, there is between laterally adjacent inserts 30 and then in The direction of conveyance arrow 20 cut out a one-piece separating part 31, which then has a transverse section 33 to be detached from the front edges of at least two inserts 30 lying next to one another and at least one longitudinal section 32 adjoining its rear edge. This longitudinal section 32, which is cut free in front of the cross section 33, is still connected in one piece to the entire web 21 with the rear end after the cross section 33 has been cut free and is cut off with the subsequent cross section 27 for the next following inserts 30, at the moment this separation is already essentially completely lifted out of the total web 21. The individual layers of the respective separating part 31 are connected to one another by crimping 34, which are distributed substantially uniformly over the width of the entire web 21 and are provided exclusively in the area of the respective transverse section 33. Immediately in front of the cross cutting device 14, the longitudinal edge 22 is cut off with a cut 35. The other longitudinal edge 23 can also be separated with a separating cut 36 in this area or in front of it, but expediently after the crimping 34 or the longitudinal cuts 25, 26 have been produced.

Die Breite des jeweiligen Längsabschnittes 32 bzw. der seitliche Abstand zwischen benachbarten Einlagen 30 wird dadurch bestimmt, daß die Längstrenneinrichtung 13 für jeden Längsabschnitt 37 zwei benachbarte Längsmesser 39,40 aufweist, die jeweils eine rotierende Schneidbewegung ausführen, mit Umfangschneiden arbeiten, mit einem gegenüber liegenden, ebenfalls drehenden Gegenmesser zusammenwirken und in ihrer Schnittkante mindestens eine Unterbrechung aufweisen. Dadurch stellt jedes Schneidmesser 39 bzw.40 Längsschnitte 25,26 vorbestimmte Länge her, die in einem vorbestimmten Abstand 37 nebeneinander und in einem vorbestimmten 38 hintereinander liegen, sowie geringfügig länger als die zugehörigen Seitenkanten der Einlagen 30 sind. Unmittelbar nach der Längstrenneinrichtung renneinrichtung 13 wird die Gesamt-Bahn 21 noch durch mindestens eine Führungseinrichtung 16 bis an die jeweils zugehörige Abtrenneinrichtung 17 bzw. 18 geführt und läuft dann unmittelbar in die Quertrenneinrichtung 14 ein.The width of the respective longitudinal section 32 or the lateral distance between adjacent inserts 30 is determined in that the longitudinal separating device 13 has two adjacent longitudinal knives 39, 40 for each longitudinal section 37, each performing a rotating cutting movement, working with circumferential cutting, with an opposite one , also cooperate rotating counter knife and have at least one break in their cutting edge. As a result, each cutting knife 39 or 40 produces longitudinal cuts 25, 26 of predetermined length, which are adjacent to one another at a predetermined distance 37 and one behind the other at a predetermined 38, and are slightly longer than the associated side edges of the inserts 30. Immediately after the longitudinal cutting device 13, the entire web 21 is still guided by at least one guide device 16 to the associated cutting device 17 or 18 and then runs directly into the cross cutting device 14.

Die Quertrenneinrichtung 14 weist eine im wesentlichen achsparallel zu den Längsmessern 39,40 drehende Schneidwalze 44 auf, die am Umfang mit einem oder mehreren, beispielsweise drei Paaren von Quermessern 41,42,43 versehen ist. Von den Quermessern jedes Paares, die wie die Längsmesser 40 entsprechend der Fördergeschwindigkeit der Gesamt-Bahn 21 mitlaufen, kommt zunächst das in Drehrichtung der Schneidwalze 44 vordere Quermesser 41 in Eingriff mit der Bahn 21 und trennt das hintere Ende des vorauslaufenden Abtrennteiles 31 in der beschriebenen Weise ab, wobei es gleichzeitig die hinteren Kanten der vorauslaufenden Einlagen 30 freischneidet. Das Quermesser 41 geht als Axialmesser im dargestellten Ausführungsbeispiel über diejenige Gesamtbreite der Bahn 21 durch, die diese im Bereich der Quertrenneinrichtung 14 hat. Das Quermesser 41 könnte auch aus einzelnen, nebeneinader liegenden Einzelmessern bestehen, so daß z.B. dasjenige Einzelmesser, daß das hintere Ende des Abtrennteiles 31 freischneidet, gegenüber den jenigen Einzelmessern, die die hinteren Kanten der Einlagen 30 freischneiden, bezogen auf die Förderrichtung Pfeil 20, geringfügig versetzt oder anders ausgebildet sein könnte.The cross cutting device 14 has a cutting roller 44 which rotates essentially axially parallel to the longitudinal knives 39, 40 and is provided on the circumference with one or more, for example three pairs of cross knives 41, 42, 43. Of the transverse knives of each pair, which run like the longitudinal knives 40 in accordance with the conveying speed of the entire web 21, the front transverse knife 41 in the direction of rotation of the cutting roller 44 first comes into engagement with the web 21 and separates the rear end of the preceding separating part 31 in that described Way, at the same time cutting free the rear edges of the leading inserts 30. In the exemplary embodiment shown, the transverse knife 41 passes over the total width of the web 21 which it has in the region of the transverse separating device 14. The transverse knife 41 could also consist of individual individual knives lying next to one another, so that, for example, the individual knife that the rear end of the separating part 31 cuts free, compared to those individual knives that cut free the rear edges of the inserts 30, with respect to the conveying direction arrow 20, could be slightly offset or could be designed differently.

Unmittelbar auf das Quermesser 41 folgend, kommen die beiden Quermesser 42,43 in Eingriff mit der Bahn 21 und schneiden die vorderen Kanten der darauffolgenden Einlagen 30 sowie den Querabschnitt 33 frei. Diese Quermesser 42,43, deren voneinander abgekehrte Enden ebenfalls über die entsprechende Gesamtbreite der Bahn 21 reichen und miteinander fluchten, haben einen Zwischenabstand voneinander, der geringfügig kleiner als der Abstand 37 zwischen den Längsmessern 39,40 ist; dieser Abstand kann etwa 15 bis 30 mm betragen. Der Abstand zwischen dem Quermesser 41 einerseits und dem Quermessern 42,43 andererseits ist geringfügig größer als die Längserstreckung 38 der Schnittunterbrechungen der Längsmesser 39,40. Dadurch schneiden die hinteren Enden der Längsschnitte 25,26 den vorderen Querschnitt 27, während ihre vorderen Enden jeweils den zugehörigen Querschnitt 28 bzw. 29 überschneiden. Die Schneidwalze 44 arbeitet mit einer drehenden Gegenwalze 45 zusammen. Auch die Abtrenneinrichtungen 17,18 und die Crimpeinrichtung 15 weisen drehende Werkzeuge auf.Immediately following the transverse knife 41, the two transverse knives 42, 43 come into engagement with the web 21 and cut free the front edges of the subsequent inserts 30 and the transverse section 33. These transverse knives 42, 43, whose opposite ends also extend over the corresponding total width of the web 21 and are aligned with one another, have an intermediate distance from one another which is slightly smaller than the distance 37 between the longitudinal knives 39, 40; this distance can be approximately 15 to 30 mm. The distance between the transverse knife 41 on the one hand and the transverse knives 42, 43 on the other hand is slightly larger than the longitudinal extent 38 of the interruptions in the cutting of the longitudinal knives 39, 40. As a result, the rear ends of the longitudinal cuts 25, 26 cut the front cross section 27, while their front ends each intersect the associated cross section 28 and 29, respectively. The cutting roller 44 works together with a rotating counter roller 45. The separating devices 17, 18 and the crimping device 15 also have rotating tools.

Zur Entfernung des jeweiligen Abtrennteiles 31, der über die zugehörige Gesamtbreite der Bahn 21 durchgeht, ist eine nur teilweise angedeutete Abtransporteinrichtung 46 vorgesehen. Diese weist in der Lücke zwischen benachbarten Quermessern 41,42,43 in einer Anlage-bzw. Umfangsfläche der Schneidwalze 44 Saugöffnungen 48 auf, welche im wesentlichen gleichmäßig über die Fläche des Querabschnittes 33 verteilt, nicht jedoch im Bereich des Längsabschnittes 32 vorgesehen sind. Die Saugöffnungen 48 stehen in Leitungsverbindung mit einem in der Schneidwalze 44 liegenden Saugkanal 47, der in nicht näher dargestellter Weise an eine Saugeinrichtung angeschlossen ist. Die Verbindung der Saugöfffnungen 48 mit der Saugquelle ist, z.B. über ein Drehschieberventil, so gesteuert, daß über die Saugöffnungen 48 bei Durchführung der zugehörigen Querschnitte angesaugt wird. Nachdem die Schneidwalze 44 etwa eine halbe Umdrehung weiter gedreht hat, bzw. nachdem das folgende Paar von Querschnitten durchgeführt ist, wird die Verbindung zwischen den Saugöffnungen 48 und der Saugquelle unterbrochen, so daß der im Bereich seines Querabschnittes 33 angesaugte Abtrennteil 31 freigegeben wird. Dieser Abtrennteil kann dann mit einer nicht näher dargestellten Absaugeinrichtung von der Schneidwalze 44 abgesaugt werden; die Absaugeinrichtung weist z.B. eine an einen Förderkanal angeschlossene Saugglokke auf, die die Schneidwalze 44 auf einem von der Bahn 21 abgekehrten, oberen Umfangsabschnitt eng, jedoch berührungsfrei umgibt. Das genannte Drehschiebeventil kann in der Drehachse der Schneidwalze 44 liegen und in unmittelbarer Abhängigkeit von deren Drehbewegung gesteuert sein.A removal device 46, which is only partially indicated, is provided to remove the respective separating part 31 which passes over the associated total width of the web 21. This points in the gap between adjacent transverse knives 41, 42, 43 in a system or. Circumferential surface of the cutting roller 44 on suction openings 48, which in are distributed substantially uniformly over the surface of the transverse section 33, but are not provided in the region of the longitudinal section 32. The suction openings 48 are in line connection with a suction channel 47 located in the cutting roller 44, which is connected in a manner not shown to a suction device. The connection of the suction openings 48 to the suction source is controlled, for example via a rotary slide valve, in such a way that suction is carried out via the suction openings 48 when the associated cross sections are carried out. After the cutting roller 44 has rotated about half a revolution further, or after the following pair of cross sections has been carried out, the connection between the suction openings 48 and the suction source is interrupted, so that the separating part 31 sucked in the region of its cross section 33 is released. This separating part can then be sucked off from the cutting roller 44 with a suction device (not shown); the suction device has, for example, a suction bell connected to a conveying channel, which tightly surrounds the cutting roller 44 on an upper peripheral section facing away from the web 21, but without contact. The rotary slide valve mentioned can lie in the axis of rotation of the cutting roller 44 and can be controlled in direct dependence on its rotary movement.

Die Fördereinrichtung 19 schließt unmittelbar an den Schnittspalt der Quertrenneinrichtung 14 mit zwei einander gegenüberliegenden Förderbändern 49,50 an, zwischen deren einander zugekehrten Trums die freigeschnittenen Einlagen 30 unter geringer Pressung und unter Aufrechterhaltung ihrer gegenseitigen Abstände auf die Träger-Bahn 7 und in die Vorrichtung 2 weitergefördert werden. Die gesamte Transportstrecke 11 liegt zumindest vom Arbeitsbereich der Quertrenneinrichtung 14 bis in den Bereich der Vorrichtung 2 in einer Ebene. Die Größe und Form der Einlagen 30 kann in einfacher Weise dadurch verändert werden, daß zumindest die Schneidwalze 44 der Quertrenneinrichtung 14 ausgewechselt wird.The conveyor device 19 directly adjoins the cutting gap of the cross-cutting device 14 with two conveyor belts 49, 50 lying opposite one another, between the mutually facing strands of which the cut-out inserts 30 are placed on the carrier web 7 with little pressure and while maintaining their mutual distances and conveyed further into the device 2. The entire transport route 11 lies at least in one plane from the working area of the cross-cutting device 14 to the area of the device 2. The size and shape of the inserts 30 can be changed in a simple manner by replacing at least the cutting roller 44 of the cross cutting device 14.

Claims (13)

  1. Apparatus for the manufacture of inserts (30) for dispatch sleeves formed by at least one insert layer, having at least one conveying line (11) for at least one insert web (3, 4), with separating means (13, 14) for the at least partial separation of at least one insert layer from the associated insert web (3, 4) and with bringing together means (2) for bringing together at least one insert layer and at least one carrier layer (7, 8), characterized in that the bringing together means (2) follow the separating means (13, 14) along the conveying line (11).
  2. Apparatus according to claim 1, characterized in that the separating means (13, 14) are constructed for the separation of at least two juxtaposed insert layers from at least one insert web (3 or 4).
  3. Apparatus according to claim 1 or 2, characterized in that the separating means (13, 14) are constructed for the production of pairs of crosscuts (27, 28, 29) for facing transverse edges of succeeding inserts (30) and that the spacing between the crosscuts (27, 28, 29) of a pair is at least approximately the same as the associated spacing of the inserts (30) of successively produced dispatch sleeves.
  4. Apparatus according to one of the preceding claims, characterized in that the separating means for separating juxtaposed insert layers are constructed for separate, juxtaposed manufactured dispatch sleeves and preferably the separating means for the separation of juxtaposed insert layers are constructed with an intermediate spacing (37), which roughly corresponds to its spacing position in the juxtaposed manufactured dispatch sleeves.
  5. Apparatus according to one of the preceding claims, characterized in that the separating means are constructed for the separation of at least one one-piece, through separation part (31) connecting at least two adjacent insert layers and preferably for the separation of a separation part (31), which connects at least two juxtaposed and/or two succeeding insert layers.
  6. Apparatus according to one of the preceding claims, characterized in that the separating means are constructed for the separation of a separation part (31) from at least one insert web (3 or 4), which extends with a transverse portion (33) at least approximately over the entire width of the insert web (3 or 4) and is preferably T-shaped and has at least one longitudinal portion (32) located between two laterally adjacent insert layers.
  7. Apparatus according to one of the preceding claims, characterized in that the separating means have at least one longitudinal separating mechanism (13) for producing longitudinal cuts (25, 26) forming with the spacing (37) adjacent longitudinal boundaries approximately parallel to the conveying direction of arrow (20) on facing longitudinal sides of adjacent insert layers of at least one insert web (3, 4) and whose ends have a spacing (38) in the longitudinal direction thereof which is slightly smaller than the predetermined longitudinal spacing of adjacent insert layers.
  8. Apparatus according to one of the preceding claims, characterized in that the separating means have a transverse separating mechanism (14), which in particular follows a longitudinal separating mechanism (13), for producing in particular pairs of crosscuts (27, 28, 29) between adjacent insert layers and of the pairs of crosscuts (27, 28, 29) preferably one and in particular front crosscut (27) in the conveying direction of arrow (20) is continuous over laterally adjacent insert layers, whilst a crosscut (28, 29) positioned behind it is interrupted between laterally adjacent insert layers.
  9. Apparatus according to one of the preceding claims, characterized in that for at least one separation part (31) located between adjacent insert layers and to be removed from at least one insert web (3 or 4) a conveying away means (46) is provided, which is preferably located in the vicinity of the separating means and between adjacent transverse cutting blades (41, 42, 43) of at least one blade pair has a driving means and in its movement path a suction device for the separation part (31).
  10. Apparatus according to one of the preceding claims, characterized in that on at least one longitudinal side of at least one insert web (3 or 4) is provided a guidance device (16), particularly a perforated edge guide located between the longitudinal separating mechanism (13) and the transverse separating mechanism (14) and preferably immediately upstream of the transverse separating mechanism (14) there is at least one separating device (17 or 18) for the associated perforated edge (22 or 23).
  11. Apparatus according to one of the preceding claims, characterized in that the separating means for producing multilayer inserts (30) are at least partly constructed for the substantially simultaneous separation of at least two superimposed insert webs (3, 4) and that preferably upstream of the separating means or upstream of the longitudinal separating mechanism (13) is provided a device for the direct reciprocal position securing of the insert webs (3, 4), such as a crimping device (15).
  12. Apparatus according to one of the preceding claims, characterized in that a device for the reciprocal position securing of superimposed insert webs (3, 4) essentially only engages on those areas of said webs (3, 4) as are associated with separation parts (31), particularly transverse portions (33) of parts (31).
  13. Apparatus according to one of the preceding claims, characterized in that it is connected directly upstream of an apparatus (2) for bringing together substantially all the layers of the dispatch sleeve and preferably between the separating means and deflecting or guide means for the carrier and top web (7, 8) there is a conveying means (19), which secures in their relative position by pressure action on both sides the adjacent inserts (30) and in particular has two facing conveyor belts (49, 50) or the like.
