Abstract

The present invention relates to a base insert device for crossed base valve bags for the formation of crossed bases in paper bags, by means of folding devices which introduce folds at the ends of the tubular sections from which the bags are produced, with one or more gluing stations, which apply glue to the regions of the folds for gluing and/or the sheets (5) provided for gluing to the base, in the gluing stations and at least one pressing station in which the folded bases and the sheets (5) are brought into contact and glued. The novelty of the present patent application is that at least one gluing station for the sheets and/or bases is provided, comprising glue outlet openings (22) which may be selectively supplied with glue, whereby the selection of the glue outlet openings (22) defines the format of the glue application (6, 7, 8, 9). Said glue outlet openings (22) are provided with at least two application heads (1) of which at least one application head (1) may be displaced in a direction (y) orthogonal to the feed direction of the sheets (5) and/or the folded bases such that as a result of the displacement, a relative movement of the two application heads (1) occurs.

Description

Die Erfindung betrifft eine Bodenlegevorrichtung für Papiersäcke nach dem Oberbegriff des Anspruchs 1.The invention relates to a bottoming device for paper sacks according to the preamble of claim 1.

Vorrichtungen dieser Art werden zur Herstellung verschiedenster Arten von Säcken eingesetzt. Zu diesen Säcken zählen beispielsweise die so genannten Ventilsäcke, in die in der Regel bei der Herstellung der Böden Ventilzettel eingelegt werden. Die Böden selbst werden häufig als Kreuzböden ausgestaltet, wie sie beispielweise in der DE 090 145 48 U1, DE 12 29 828 B und der DE 3020043 A1 dargestellt sind. Um den Böden und den eingelegten Ventilzetteln einen dauerhaften Zusammenhalt zu verleihen, werden Teile der Böden untereinander und/oder mit den Ventilzetteln mit Hilfe von Leim verklebt.Devices of this type are used for the production of various types of bags. These sacks include, for example, the so-called valve sacks, in which valve sheets are generally inserted in the production of the bottoms. The bottoms themselves are often designed as cross bottoms, as shown for example in DE 090 145 48 U1, DE 12 29 828 B and DE 3020043 A1. In order to give the floors and the inserted valve leaflets a permanent cohesion, parts of the floors are glued to each other and / or with the valve leaflets with the help of glue.

Zu diesem Zweck werden entweder die zu verklebenden Bereiche der Bodenfaltungen oder die ihnen zugeordneten Zettel, also alle miteinander zu verklebende Bereiche, mit einem Leimauftrag versehen und anschließend durch Zusammenführung oder -faltung miteinander verklebt.For this purpose, either the areas of the bottom folds to be bonded or the strips associated with them, that is to say all areas to be bonded together, are provided with a glue application and then glued together by means of combining or folding.

Ein formatgerechter Leimauftrag erfolgt in der Regel, indem ein auf einer rotierenden Walze befestigtes Formatteil bei einer Umdrehung der Walze mit einer Leimwalze oder sonstigen Leimspeicher- oder Übertragungsteilen in Kontakt gebracht und dabei mit Leim beaufschlagt wird. Im weiteren Verlauf der Walzendrehung überträgt die Formatplatte den auf ihr gespeicherten Leim auf die jeweils zu verklebenden Bereiche der späteren Sackböden oder der Zettel. Zu diesem Zweck ist das Formatteil mit charakteristischen Erhöhungen versehen, die auf ein bestimmtes Sackformat abgestimmt ist. Zur Herstellung von Säcken mit anderen Formaten auf der Bodenlegevorrichtung werden die Formatteile ausgetauscht. Diese Art des Leimauftrags hat sich bewährt, da so große Mengen des schwierig handhabbaren Stärkeleims sauber und formatgerecht auftragbar sind.A size-appropriate application of glue is usually carried out by bringing a mounted on a rotating roller format part in a turn of the roller with a glue roller or other Leimspeicher- or transfer parts in contact and thereby applied with glue. In the further course of the roller rotation, the format plate transfers the glue stored on it to the respectively to be bonded areas of the later bag bottoms or the slip. For this purpose, the format part is provided with characteristic elevations that are specific to a particular Sack format is tuned. For the production of bags of other formats on the Bodenlegevorrichtung the format parts are exchanged. This type of glue application has proven itself, because so large quantities of difficult-to-handle starch glue can be applied cleanly and in the right format.

Unter "formatgerechter Leimauftrag" ist hierbei eine auf die Art und das Format des Sackes abgestimmte Auftragsform. Der Auftrag innerhalb dieser Auftragsform erfolgt in der Regel flächig, wobei oft den Rändern der Form besondere Bedeutung für die Haltbarkeit und Dichtigkeit der Säcke zukommt.Under "format-appropriate glue application" here is an order form matched to the type and format of the bag. The order within this order form is usually flat, often the edges of the mold is of particular importance for the durability and tightness of the bags.

Nachteilig ist dabei allerdings, dass für diese Vorrichtungen eine Vielzahl von Leimübertragungskomponenten, beispielsweise Formatwalzen und Formatteile, vorgehalten und auch nach Gebrauch wieder gereinigt werden müssen.The disadvantage here, however, that for these devices a variety of glue transfer components, such as format rollers and format parts, held and must be cleaned again after use.

Aufgabe der Erfindung ist es daher, die Bodenlegevorrichtung derart weiterzubilden, dass auf diese Teile verzichtet oder deren Zahl zumindest reduziert werden kann und dennoch ein formatgerechtes Auftragen des Leims möglich ist.The object of the invention is therefore to further develop the Bodenlegevorrichtung such that dispensed with these parts or their number can be at least reduced and still a format-appropriate application of the glue is possible.

Die vorliegende Erfindung geht von den hinlänglich bekannten Bodenlegevorrichtungen aus, welche ausschließlich über Beleimungsstationen verfügen, die Formatteile zur Definition des Leimauftragsformats benötigen.The present invention is based on the well-known bottom-laying devices which exclusively have gluing stations which require format parts for defining the size of the glue application.

Die obenstehende Aufgabe wird gelöst durch eine Bodenlegevorrichtung mit zumindest einer Beleimungsstation für Zettel und/oder Böden

  • ■ welche über Leimaustrittsöffnungen verfügt, welche selektiv mit Leim versorgbar sind, wobei durch die Auswahl der Leimaustrittsöffnungen das Format des Leimauftrags definierbar ist,
  • ■ wobei diese Leimaustrittsöffnungen zumindest zwei Auftragsköpfen zugeordnet sind
  • ■ von denen zumindest ein Auftragskopf in einer Richtung orthogonal zur Förderrichtung der Zettel und/oder der gefalteten Böden derart verschiebbar ist, dass durch die Verschiebung eine Relativbewegung der zumindest zwei Auftragsköpfe stattfindet.
The above object is achieved by a Bodenlegevorrichtung with at least one gluing station for labels and / or floors
  • ■ which has glue outlet openings which can be supplied selectively with glue, wherein the format of the glue application can be defined by the selection of the glue outlet openings,
  • ■ wherein these glue outlet openings are assigned at least two guns
  • ■ Of which at least one applicator head in a direction orthogonal to the conveying direction of the slip and / or the folded bottoms is displaced so that takes place by the displacement, a relative movement of the at least two applicator heads.

Der erste Unterpunkt der kennzeichnenden Teils befasst sich mit der Definition des Leimauftrags durch die Extrusion von Leim aus selektiv mit Leim versorgbaren Leimaustrittsdüsen. Durch das Öffnen und Schließen von Leimventilen kann bestimmt werden, welche Leimaustrittsöffnungen mit Leim versorgt werden und welche nicht. Die Art, in welcher das Leimprofil zustande kommt, ist in der noch unveröffentlichten DE 103 09 893 beschrieben. Im Gegensatz zu dieser Anmeldung umfasst die vorliegende Erfindung jedoch auch Vorrichtungen, welche Leim nicht direkt auf Sackbestandteile extrudieren, sondern das Leimprofil zunächst einem anderen Maschinenbestandteil wie einer Walze bilden und dann auf die Sackbestandteile übertragen.The first sub-item of the characterizing part deals with the definition of glue application by the extrusion of glue from glue-dispensable glue-dispensable nozzles. By opening and closing of glue valves can be determined which glue outlet openings are supplied with glue and which not. The way in which the glue profile comes about, is described in the unpublished DE 103 09 893. However, in contrast to this application, the present invention also encompasses devices which do not extrude glue directly to sack components, but first form the sizing profile to another machine component such as a roller and then transfer it to the sack components.

Die vorgenannten Ventile sind in der Regel an eine oder mehrere Leimleitungen oder -Reservoirs angeschlossen, in welchen der Leim einem Druck ausgesetzt ist.The aforementioned valves are typically connected to one or more glue lines or reservoirs in which the glue is subjected to pressure.

Auftragsköpfe im Sinne der vorliegenden Anmeldung sind Maschinenbestandteile, welche mit Leimaustrittsöffnungen versehen sind. In der Regel werden diese Auftragsköpfe eine Vielzahl von Öffnungen umfassen, mit Leimversorgungsleitungen ausgestattet sein und auch eine Mehrzahl von Ventilen tragen. Falls eine Beleimungsstation nur über einen Auftragskopf verfügt, ist der Abstand der Leimaustrittsöffnungen in der Richtung quer zur Förderrichtung der Zettel oder Schlauchstücke entscheidend für die Genauigkeit, mit der beliebige Leimprofile nachgebildet werden können. Aufgrund der obengenannten Aufgaben eines Auftragskopfes ist dieser Abstand jedoch nicht beliebig minimierbar. Werden zwei oder mehr Auftragsköpfe vorgesehen, deren Relativpositionen in der Richtung quer zur Förderrichtung der Zettel oder Schlauchstücke veränderbar ist, so wird die Möglichkeit des formatgerechten Auftrags erheblich verbessert. Insbesondere das Versehen der Ränder des zu beleimenden Zettel und/oder Bereiche des Sackbodens mit ausreichenden Mengen Leims ist hierbei von besonderer Bedeutung.In the context of the present application, application heads are machine components which are provided with glue outlet openings. Typically, these applicator heads will comprise a plurality of openings, be provided with glue supply lines and also carry a plurality of valves. If a gluing station has only one application head, the distance of the glue outlet openings in the direction transverse to the conveying direction of the slips or pieces of hose is decisive for the accuracy with which any glue profiles can be simulated. Due to the above-mentioned tasks of an application head, however, this distance can not be minimized as desired. If two or more application heads are provided, whose relative positions in the direction transverse to the conveying direction of the pieces of paper or pieces of hose can be varied, the possibility of the format-appropriate order is considerably improved. In particular, the provision of the edges of the paper to be glued and / or areas of the sack with sufficient quantities of glue is of particular importance here.

Vorteilhafterweise ist jedem Auftragskopf eine Auftragsplatte zugeordnet, in der jeweils mehrere Leimaustrittsöffnungen äquidistant auf einer Linie in der Richtung quer zur Förderrichtung der Zettel und/oder der Faltungen der Böden angeordnet sind, wobei die Auftragsplatten so angeordnet sind, dass die benachbarten Leimaustrittsöffnungen zweier verschiedener Auftragsköpfe einen geringeren als den beschriebenen äquidistanten Abstand einnehmen können. Dies kann dadurch erreicht werden, dass die Auftragsplatten leicht versetzt auf den Auftragsköpfen angeordnet sind. Bei beispielsweise drei Auftragsköpfen kann die Auftragsplatte mittig an dem mittleren Auftragskopf angebracht werden, wogegen die Auftragsplatten an den äußeren Auftragsköpfen leicht zum mittleren Auftragskopf hin verschoben angebracht sein können. Auf diese Weise wird erreicht, dass, wenn die äußeren Auftragsköpfe nach außen verschoben wurden, an den Grenzen zu den benachbarten Auftragsköpfen kein zu großer Abstand zwischen den Leimaustrittsöffnungen und damit zwischen den späteren Leimspuren entsteht. Ein zu großer Abstand könnte zu einem nicht ausreichenden Leimauftrag führen.Advantageously, each applicator head is assigned an application plate in which a plurality of glue outlet openings are arranged equidistantly on a line in the direction transverse to the conveying direction of the labels and / or the folds of the trays, wherein the application plates are arranged so that the adjacent glue outlet openings of two different applicator heads a lower than that described equidistant distance can take. This can be achieved by arranging the application plates slightly offset on the applicator heads. For example, with three guns, the platen can be mounted centrally on the center gun, whereas the platen can be easily mounted on the outer guns slightly toward the center gun. In this way, it is achieved that, when the outer application heads have been moved outward, at the borders to the adjacent guns no too large distance between the glue outlet openings and thus between the subsequent glue marks. Too long a distance could lead to an insufficient glue application.

In einer bevorzugten Ausführungsform der Erfindung sind Mittel zur automatischen Verschiebung zumindest eines Auftragskopfes und eine Steuerung vorgesehen, welche die Verschiebung steuert. Auf diese Weise ist es möglich, auf eine manuelle Verschiebung der Auftragsköpfe zu verzichten, wodurch die beschriebenen Beleimungsstationen kompakter gebaut werden können.In a preferred embodiment of the invention, means for automatically displacing at least one applicator head and a controller are provided which controls the displacement. In this way it is possible to dispense with a manual displacement of the applicator heads, whereby the Beleimungsstationen described can be made more compact.

Vorteilhaft ist es dabei, wenn der Steuerung das Sollbild des Leimauftrages zuführbar ist und wenn die Steuerung über Mittel verfügt, aus diesem Sollbild Sollpositionen der von den Leimaustrittsöffnungen zu extrudierenden Leimspuren zu errechnen. Das Sollbild kann dabei der Steuerung von außen zugeführt werden, beispielsweise über eine manuelle Eingabe oder aus einem Speicher, der eine Mehrzahl solcher Sollbilder enthalten kann. Aufgrund der aus diesem Sollbild errechneten Sollpositionen der Leimspuren auf dem Zettel und/oder zu dem zu beleimenden Bodenbereich kann dann die Steuerung die Verschiebung der Auftragsköpfe steuern.It is advantageous if the control of the target image of the glue application can be fed and if the controller has means to calculate from this target image set positions of the glue outlets to be extruded glue tracks. The target image can be supplied to the controller from the outside, for example via a manual input or from a memory which may contain a plurality of such target images. On the basis of the setpoint positions of the glue tracks calculated on the label and / or on the floor area to be glued, the control can then control the displacement of the application heads.

Dabei ist es vorteilhaft, Positionssensoren vorzusehen, welche die Istposition zumindest einer Spindel aufzeichnen und der Steuereinheit melden. Mit der Istposition der Spindel ist auch gleichzeitig die Istposition der Auftragsköpfe, also deren Relativposition zu den die Zettel oder die Boden transportierenden Maschinenteilen, bekannt. Durch den Abgleich von Soll- und Istposition der Auftragsköpfe kann eine fehlerfreie Positionierung der Auftragsköpfe sichergestellt werden.It is advantageous to provide position sensors which record the actual position of at least one spindle and report to the control unit. With the actual position of the spindle, the actual position of the application heads, ie their relative position to the machine parts transporting the labels or the floor, is also known at the same time. By balancing the setpoint and actual position of the application heads, an error-free positioning of the application heads can be ensured.

In weiterer Ausgestaltung der Erfindung ist eine gemeinsame Leimversorgungsleitung vorgesehen, aus welcher alle Auftragsköpfe der zumindest einen Beleimungsstation mit Leim versorgt werden. Im Sinne der Erfindung bedeutet eine gemeinsame Leimversorgungsleitung, dass alle Auftragsköpfe aus dieser einen Leitung mit Leim versorgt werden. Die Leimeinspeisung kann jedoch an einem beliebigen Punkt der Leimversorungsleitung liegen, so dass sich der Leimstrom am Einspeisepunkt teilt, aber ab dem Einspeisepunkt eine serielle Versorgung der Auftragsköpfe mit Leim erfolgt. Vorteilhafterweise verläuft die Leimversorgungsleitung im wesentlichen in einer Richtung orthogonal zur Förderrichtung der Zettel, so dass eine möglichst direkt Versorgung aller Ventile mit Leim erfolgt.In a further embodiment of the invention, a common glue supply line is provided, from which all application heads of the at least one gluing station are supplied with glue. For the purposes of the invention, a common glue supply line means that all the application heads are supplied with glue from this one line. However, the glue feed may be at any point on the glue supply line so that the glue stream will divide at the feed point, but from the feed point there will be a serial supply of glue to the applicator heads. Advantageously, the glue supply line extends substantially in a direction orthogonal to the conveying direction of the slip, so that as direct as possible supply of all valves with glue.

Besonders vorteilhaft ist es dabei, wenn die Leimversorgungsleitung als Führungsschiene ausgebildet ist. Zu diesem Zweck kann die Leimversorgungsleitung als Rohr ausgeformt sein, welches im Bereich der Auftragsköpfe Bohrungen ausweist, so dass dort der Leim austreten kann.It is particularly advantageous if the glue supply line is designed as a guide rail. For this purpose, the glue supply line may be formed as a tube, which identifies bores in the region of the applicator heads, so that the glue can escape there.

Eine vorteilhafte Ausgestaltung der Erfindung umfasst Führungselemente, welche die zu beleimenden Sackbestandteile im Bereich der zumindest einen Beleimungsstation führen. Dabei sind die Führungselemente gemeinsam mit dem zumindest einen verschiebbaren Auftragskopf verschiebbar. Auf diese Weise ist sichergestellt, dass die Sackbestandteile während des Beleimungsvorgangs eine definierte Position relativ zu den Auftragsköpfen einnehmen. So kann beispielsweise gewährleistet werden, dass die Sackbestandteile fest auf die sie fördernden Walzen gedrückt werden.An advantageous embodiment of the invention comprises guide elements which guide the sack components to be glued in the region of the at least one gluing station. In this case, the guide elements are displaceable together with the at least one displaceable applicator head. In this way it is ensured that the bag components occupy a defined position relative to the gun during the gluing process. For example, it can be ensured that the sack components are pressed firmly onto the rollers that feed them.

Fig. 1 zeigt einen Auftragskopf 1, wie er in einer Beleimungsstation in der erfindungsgemäßen Bodenlegevorrichtung Verwendung findet. Dieser Auftragskopf 1 setzt sich zusammen aus einer Auftragsplatte 2, an welcher Ventile 3 angebracht sind. Der Leim wird dem Auftragskopf 1 über die Leimzuleitung 4 zugeführt. Der Beleimungsstation werden in Richtung x unbeleimte Zettel 5 zugeführt.Fig. 1 shows a gun 1, as it is used in a Beleimungsstation in Bodenlegevorrichtung invention. This application head 1 is composed of a job plate 2, to which valves 3 are attached. The glue is supplied to the application head 1 via the glue supply line 4. The gluing station are fed in the direction x unprimed labels 5.

Jedem Ventil 3 ist in der den unbeleimten Zetteln 5 zugewandten Seite der Auftragsplatte 2 einer oder einer Gruppe von Leimaustrittsöffnungen zugeordnet. Der Leimfluss zu der Leimaustrittsöffnung kann durch das zugeordnete Ventil 3 hergestellt oder unterbrochen werden. Auf diese Weise ist es möglich, auf die unbeleimten Zettel 5 verschiedene Leimspuren, die parallel zu der Förderrichtung x der unbeleimten Zettel 5 verlaufen, aufzubringen. Durch regelmäßiges Öffnen und Schließen des Ventils 3 kann eine regelmäßig unterbrochene Leimspur 5 aufgetragen werden. Ebenfalls herstellbar sind kurze Leimspuren 7, unterbrochene Leimspuren 8 und durchgehende Leimspuren 9. Befindet sich unter dem Auftragskopf 1 kein unbeleimter Zettel 5, so wird der Leimfluss durch alle Ventile 3 unterbrochen, um nicht die Beleimungsstation unnötig zu verschmutzen. Um alle Bereiche der unbeleimten. Zettel in Richtung y quer zur Förderrichtung beleimen zu können, ist der Auftragskopf 1 ebenfalls in dieser Richtung verschiebbar. Der soeben beschriebene Auftragskopf 1 lässt sich jedoch nicht nur zur Beleimung von Zetteln 5 verwenden, sondern eignet sich aufgrund einer Variabilität der erzeugbaren Leimspuren auch zum Leimauftrag auf die zu verklebenden Bereiche des späteren Sackbodens.Each valve 3 is assigned in the non-glued sheets 5 side facing the application plate 2 one or a group of glue outlet openings. The glue flow to the glue outlet opening can be made or interrupted by the associated valve 3. In this way, it is possible to apply 5 different glue tracks on the unprimed label, which run parallel to the conveying direction x of the unprimed label 5. By regularly opening and closing the valve 3, a regularly interrupted glue trace 5 can be applied. Also can be produced are short traces of glue 7, broken glue marks 8 and continuous glue traces 9. If there is no unsealed note 5 under the application head 1, the glue flow is interrupted by all valves 3 so as not to unnecessarily contaminate the glueing station. To all areas of the unprimed. To be able to glue labels in the direction of y transversely to the conveying direction, the application head 1 is also displaceable in this direction. However, the applicator head 1 just described can not only be used for gluing sheets 5, but is also suitable for applying glue to the areas of the subsequent bottom of the sack to be bonded due to the variability of the glue tracks that can be produced.

Die Figuren 2 und 3 zeigen eine Beleimungsstation in einer erfindungsgemäßen Bodenlegevorrichtung, in der drei Auftragsköpfe 1 vorgesehen sind. Die beiden äußeren Auftragsköpfe 1 sind in Richtung y verschieblich auf einer Führungsschiene 13 gelagert. Der mittlere Auftragskopf 1 kann fest mit der Führungsschiene 13 verbunden sein. Die Führungsschiene 13 ist über den Tragarm 12 an der Strebe 11 befestigt, welche wiederum in den beiden Teilen des Rahmens 10 verschieblich in Richtung y gelagert ist. Eine Verschiebung der Strebe 11 und damit des mittleren Auftragskopfes 1 erfolgt durch die Betätigung des Antriebs 17, welcher beispielsweise ein Schrittmotor sein kann. An den äußeren Auftragsköpfen 1 sind Halter 14 fest angebracht. Die Halter 14 umfassen Gewindebohrungen, die als Spindelmuttern dienen und in welche Spindeln 15 eingeschraubt sind. Die Spindeln 15 sind drehbar, aber unverschieblich im Tragarm 12 gelagert. Der Antrieb der Spindeln 15 erfolgt über die Antriebseinheiten 16, die auf nicht näher dargestellte Weise mit dem Tragarm 12 verbunden sind. In dieser Beleimungsstation lassen sich die äußeren Auftragsköpfe 1 unabhängig voneinander derart verfahren, dass sich auch - in Richtung y betrachtet - die äußeren Ränder der in diesen Figuren nicht gezeigten Zettel beleimen lassen. Die Zettel laufen auf der Walze 18 in der in Fig. 3 angedeuteten Richtung x und werden dabei von den Führungselementen 19 auf dieser Walze 18 gehalten. Über die Halter 20 sind die Führungselemente 19 mit den Auftragsköpfen 1 verbunden, so dass die Führungselemente 19 mit der Verschiebung der Auftragsköpfe 1 ebenfalls mit verschoben werden.Figures 2 and 3 show a gluing station in a Bodenlegevorrichtung invention, in which three applicator heads 1 are provided. The two outer application heads 1 are mounted displaceably in the direction y on a guide rail 13. The middle application head 1 can be firmly connected to the guide rail 13. The guide rail 13 is attached via the support arm 12 to the strut 11, which in turn is mounted in the two parts of the frame 10 displaceable in the direction y. A displacement of the strut 11 and thus of the central application head 1 is effected by the actuation of the drive 17, which may be, for example, a stepper motor. At the outer applicator heads 1 holder 14 are firmly attached. The holders 14 comprise threaded bores which serve as spindle nuts and into which spindles 15 are screwed. The spindles 15 are rotatable but non-displaceably mounted in the support arm 12. The drive of the spindles 15 via the drive units 16, which are connected in a manner not shown with the support arm 12. In this gluing station, the outer application heads 1 can be moved independently of each other in such a way that - viewed in direction y - the outer edges of the sheets, not shown in these figures, can also be glued. The sheets run on the roller 18 in the direction indicated in Fig. 3 x direction and are held by the guide elements 19 on this roller 18. About the holder 20, the guide elements 19 are connected to the applicator heads 1, so that the guide elements 19 are also moved with the displacement of the applicator heads 1 with.

Die Figuren 4 und 5 zeigen die drei in den Figuren 2 und 3 gezeigten Auftragsköpfe 1 in einer schematischen Darstellung. Von den Auftragsköpfen 1 sind im wesentlichen die Ventile 3 erkennbar, welche praktisch ohne Zwischenräume auf dem Auftragskopf 1 angeordnet sind. Jedes Ventil 3 kann Leim in die Leimverteilungskanäle 21 geben, welche in die Auftragsplatte 2 eingebracht sind. Die Leimverteilungskanäle 21 verteilen den Leim auf zwei Leimaustrittsöffnungen 22. Selbstverständlich kann auch eine kleinere oder größere Zahl an Leimaustrittsöffnungen 22 vorgesehen werden, wobei jedoch der Leimaustritt nur gleichzeitig für alle einem Ventil 3 zugeordneten Leimaustrittsöffnungen 22 hergestellt oder unterbrochen werden kann. Die Leimaustrittsöffnungen 22 sind so angeordnet, dass sie einen äquidistanten Abstand A voneinander einnehmen.Figures 4 and 5 show the three applicator heads 1 shown in Figures 2 and 3 in a schematic representation. Of the applicator heads 1, the valves 3 are essentially visible, which are arranged virtually without gaps on the applicator head 1. Each valve 3 can add glue into the glue distribution channels 21, which are introduced into the application plate 2. The glue distribution channels 21 distribute the glue on two glue outlet openings 22. Of course, a smaller or larger number of glue outlet openings 22 may be provided, but the glue outlet can only be made or interrupted simultaneously for all of a valve 3 associated glue outlet openings 22. The glue outlet openings 22 are arranged so that they occupy an equidistant distance A from each other.

Die Auftragsplatten 2 sind an den Rändern derart eingekürzt, dass der Abstand zwischen diesen Rändern und der jeweils ersten Leimaustrittsöffnung 22 kleiner ist als die Hälfte des Abstandes A. Zudem sind die Auftragsplatten 2 der beiden äußeren Auftragsköpfe 1 leicht zum mittleren Auftragskopf 1 hin verschoben befestigt. Auf diese Weise ist der Abstand zwischen zwei benachbarten Leimaustrittsöffnungen 22, welche aber zu zwei verschiedenen Auftragsplatten 2 gehören, im zusammengefahrenen Zustand kleiner als der Abstand A zwischen den Leimaustrittsöffnungen 22 an einer Auftragsplatte 2. Diese Situation ist in Fig. 5 dargestellt. Durch die dargestellte Ausführungsform ist es möglich, die Auftragsköpfe 1 über einen weiten Verstellbereich auseinander zu fahren, ohne dass die benachbarten Leimaustrittsöffnungen 22, welche aber zu zwei verschiedenen Auftragsplatten 2 gehören, einen größeren Abstand als den Abstand A einnehmen. Selbstverständlich ist es auch möglich, die Auftragsköpfe soweit zu verfahren, dass die benachbarten Leimaustrittsöffnungen 22 einen größeren Abstand als den Abstand A einnehmen.

In addition, the application plates 2 of the two outer applicator heads 1 are slightly shifted to the middle application head 1 out. In this way, the distance between two adjacent glue outlet openings 22, which belong to two different application plates 2, in the contracted state is smaller than the distance A between the glue outlet openings 22 on a job plate 2. This situation is shown in Fig. 5. By the illustrated embodiment, it is possible to drive apart the applicator heads 1 over a wide adjustment range, without the adjacent glue outlet openings 22, which belong to two different application plates 2, occupy a greater distance than the distance A. Of course, it is also possible to move the guns far enough that the adjacent glue outlet openings 22 occupy a greater distance than the distance A.
