Zur Verminderung der Antriebsleistung des für die relative Verstellung notwendigen Stellantriebs für die Perforierbrücken können die schalenartig die Perforierzylinder umgebenden Perforierbrücken in Lagerungen an den Zylinderachsen aufgenommen werden.The perforation bars for the perforation cylinders, which are stationary on the perforation cylinders as standard Delta fold and second cross fold (double parallel fold) can also be used on others Perforating bridges are included, which are coaxial to the cylinder axes of the Perforating cylinders are stored. To reduce the drive power for the relative Adjustment of the necessary actuator for the perforating bridges can be made like a shell Perforating bridges surrounding perforating cylinders in bearings on the cylinder axes be included.

In in vorteilhafter Weise komplette Stirnzahnräderzüge vermeidender Ausführungsweise können die Perforierbrücken über Übertragungselemente verstellt werden, die als Kulissenführungen auf den antriebseitig vorgesehenen Zylinderachszapfen der Perforierzylinder aufgenommen sind. Als den Verstellweg übertragende Elemente lassen sich sehr vorteilhaft und fertigungstechnisch günstig auf den Außenseiten der Kulissenführungen Außenverzahnungen vorsehen, die mit entsprechenden Verzahnungen an den Perforierbrücken zusammenarbeiten, um eine Relativpositionierung der die Perforierwerkzeuge aufnehmenden Perforierbrücken relativ zum Mantel der Perforierzylinder zu erreichen.In an advantageous manner, complete spur gear train avoiding embodiment the perforating bridges can be adjusted via transmission elements, which as Link guides on the cylinder axle journals provided on the drive side Perforating cylinders are included. Leave as elements transferring the adjustment path very advantageous and technically favorable on the outside of the Link guides provide external gears with the corresponding gears work together on the perforating bridges to achieve a relative positioning of the Perforating bridges receiving perforating tools relative to the jacket of the Reach perforating cylinder.

Da einer der Perforierzylinder in Bezug auf den Perforierspalt verstellbar ist, um die Perforationstiefe in den Materialbahnen zu variieren, ist zwischen den über eine gemeinsame Verstelleinheit betätigbaren Perforierbrücken eine Ausgleichsmechanik aufgenommen, die die gemeinsame Veränderung der Umfangspositionen der Perforierbrücken an den Zylindern zuläßt, ohne daß die Geometrie des Perforierspaltes durch die Lage des verstellbaren Perforierzylinders beeinträchtigt werden würde.Since one of the perforating cylinders is adjustable in relation to the perforating gap, the Varying the depth of perforation in the material webs is between the one common adjustment unit operated perforating bridges a compensation mechanism included the common change in circumferential positions of the Perforating bridges on the cylinders allow without the geometry of the perforating gap would be affected by the location of the adjustable perforating cylinder.

Die erfindungsgemäße Vorrichtung eignet sich zum Einsatz sowohl in Falzapparaten mit Punkturensätzen als auch in solchen ohne Punkturen, sowohl für den Akzidenz- als auch für den Zeitungsdruck.The device according to the invention is suitable for use both in folders and with Puncture sets as well as in those without punctures, both for the commercial as well as for newspaper printing.

Die Darstellung gemäß Fig. 1 gibt den schematischen Aufbau und den Ablauf von Querfalzvorgängen in einem Falzapparat wieder.1 shows the schematic structure and the sequence of Cross folds in a folder again.

Eine auch aus mehreren Bahnlagen bestehende bedruckte Materialbahn 1 läuft in Bahnlaufrichtung 2 vertikal orientiert in den Falzapparat ein, wobei sie zwischen den miteinander zusammenarbeitenden Perforierzylindern 3, 4 so perforiert wird, daß die Perforationen in Querrichtung der Materialbahn 1 verlaufend mit den Positionen der Querfalz übereinstimmen. Das Perforierwerkzeug 5 auf dem stationär aufgenommenen Perforierzylinder 3 und das Perforierwerkzeug 6 auf dem zustellbaren Perforierzylinder 4 dienen der Perforation der Falzrücken beim zweiten Querfalz (Doppelparallelfalz), wohingegen das am stationär gelagerten Perforierzylinder 3 vorgesehene Perforierwerkzeug 7 für den ersten Querfalz vorgesehen ist. Bei bisherigen Querperforationseinrichtungen war eine Umstellung der Perforierwerkzeuge nur nach Anhalten der Rotation und nachfolgender Verstellung möglich.A printed material web 1 also consisting of several web layers runs in Web running direction 2 is oriented vertically into the folder, being between the cooperating perforating cylinders 3, 4 is perforated so that the Perforations running in the transverse direction of the material web 1 with the positions of the Cross fold match. The perforating tool 5 on the stationary Perforating cylinder 3 and the perforating tool 6 on the deliverable perforating cylinder 4 serve to perforate the fold back in the second cross fold (double parallel fold), whereas that provided on the stationary perforating cylinder 3 Perforating tool 7 is provided for the first transverse fold. With previous ones Cross perforation equipment was only a conversion of the perforating tools after Stopping the rotation and subsequent adjustment possible.

Nach erfolgter Perforation werden vom in Bahnlaufrichtung 2 vorlaufenden Ende der Materialbahn 1 Exemplare 12 abgetrennt, die dem auch aus mehreren einzelnen übereinander liegenden Lagen je nach Anzahl der in der Materialbahn 1 aufgenommenen Bahnstränge bestehen können. Die Exemplare 12 werden vom Falzzylinder 9 übernommen, an dessen Umfangsfläche 11 transportiert und durch Aktivieren des Falzmessers 10, welches aus dem Umfang 11 des Falzzylinders 9 ausfährt, in die Falzklappen eines hier nicht näher dargestellten mit dem Falzzylinder 9 zusammenarbeitenden Falzklappenzylinder eingestoßen. Demnach entsteht der Falzrücken 15 zwischen den Enden 13 und 14 des Exemplars 12, wodurch der erste Quer- bzw. erste Parallelfalz gebildet wird. Durch einen hier nicht näher gezeigten Übergang der gefalzten Exemplare 12 an einen weiteren Falzzylinder 16, wobei der Exemplarübergang nicht Gegenstand der vorliegenden Erfindung ist, erfolgt eine Aufnahme des Exemplars 12 an dessen Umfangsfläche 18 und die sich daran anschließende Ausbildung des zweiten Querfalzes durch Ausfahren des Falzmessers 17 und Falzung des bereits einmal quergefalzten Exemplars 12. Es entsteht ein doppelt quergefaltetes Exemplar 22 mit Enden 24 und 25, wobei am zweiten Querfalz (Doppelparallelfalz) der Falzrücken 23 ausgebildet ist.After the perforation has taken place, the end of the leading end in the direction of web travel 2 Material web 1 copies 12 separated, which also consists of several individual Superimposed layers depending on the number of 1 recorded in the material web Web strands can exist. The copies 12 are from the folding cylinder 9 taken, transported on its peripheral surface 11 and by activating the Folding knife 10, which extends from the circumference 11 of the folding cylinder 9, into the Folding flaps of one not shown here with the folding cylinder 9 Collaborating jaw cylinder pushed in. This creates the fold back 15 between the ends 13 and 14 of the specimen 12, whereby the first transverse or first Parallel fold is formed. By a transition of the folded one, not shown here Copies 12 to a further folding cylinder 16, the copy transition not The subject of the present invention is a copy of the copy 12 the peripheral surface 18 and the subsequent formation of the second Cross fold by extending the folding knife 17 and folding the one time cross-folded copy 12. A double cross-folded copy 22 with ends is produced 24 and 25, the fold back 23 being formed on the second transverse fold (double parallel fold) is.

Im Deltafalzmodus wird das Exemplar im Vergleich zum Doppelparallelfalzmodus zweimal gefalzt, jedoch an verschiedenen Stellen, während bei Doppelparallelfalz je nach eingestelltem Überfalz eine beim ersten und zweiten Querfalz erfolgende hälftige Falzung am Exemplar 12 erfolgt, wodurch ein Exemplar 22 entsteht. Nach erfolgter Querfalzung, sei es im Deltafalzmodus oder im Doppelparallelfalzmodus, werden die solcherart gefalzten Exemplare 12, 22 über einen Transportzylinder 20 zu einer gegebenenfalls vorgesehen zweiten Längsfalzeinrichtung transportiert, oder direkt zur Auslage gebracht.In the delta fold mode, the copy is compared to the double parallel fold mode Folded twice, but in different places, while depending on the double parallel fold set overlap half fold at the first and second cross fold on copy 12, which creates a copy 22. After cross folding, be it in delta folding mode or in double parallel folding mode, the copies 12, 22 folded in this way become a via a transport cylinder 20 optionally provided second longitudinal folding device transported, or directly to Brought display.

Fig. 2 zeigt die Seitenansicht auf ein Perforierzylinderpaar 3, 4, wobei zwischen den Umfangsflächen 33 und 34 der Perforierzylinder 3, 4 ein Perforierspalt 26 für die das Perforierzylinderpaar 3, 4 passierende Materialbahn 1 vorgegeben ist. Je nach Dicke der zu verarbeitenden Materialbahn 1 kann der Perforierzylinder 4 näher an den Umfang des festgelagerten Perforierzylinders 3 angestellt oder weiter von diesem abgestellt werden. dadurch läßt sich die Durchdringungstiefe der zu erzeugenden Perforationen in den die Materialbahn 1 bildenden Bahnlagen einstellen und gegebenenfalls verändern.Fig. 2 shows the side view of a pair of perforating cylinders 3, 4, wherein between the Circumferential surfaces 33 and 34 of the perforating cylinders 3, 4 a perforating gap 26 for the Perforating cylinder pair 3, 4 passing material web 1 is specified. Depending on the thickness of the processing material web 1, the perforating cylinder 4 can be closer to the circumference of the fixed perforating cylinder 3 employed or further turned off by this. this allows the depth of penetration of the perforations to be created in the Set the web layers forming material web 1 and change if necessary.

Koaxial zu den Zylinderachsen 31, 32 der Perforierzylinder 3 und 4 sind in dem dargestellten Ausführungsbeispiel je Perforierzylinder 3, 4 eine Perforierbrücke 27, 28 vorgesehen, auf der variabel positionierbare Perforierwerkzeuge aufgenommen sind. Es können pro Perforierzylinder 3, 4 auch zwei Perforierbrücken vorgesehen werden, vgl. 27.1 und 28.1 in Fig. 4. An den in Fig. 2 dargestellten Perforierbrücken 27 , 28 befinden sich die Perforierwerkzeuge 38.1 für den Deltafalz bzw. das Perforierwerkzeug 36.1 für den zweiten Querfalz. Diese arbeiten mit den stationär am Umfang 34 des verstellbar gelagerten Perforierzylinders 4 vorgesehenen Perforierleisten 36.2 für den zweiten Querfalz bzw. 38.2 für den Deltafalz zusammen.Coaxial to the cylinder axes 31, 32 of the perforating cylinders 3 and 4 are in the The illustrated embodiment shows a perforating bridge 27, 28 for each perforating cylinder 3, 4 provided on which variably positionable perforating tools are accommodated. It two perforating bridges can also be provided per perforating cylinder 3, 4, cf. 27.1 and 28.1 in FIG. 4. Located on the perforating bridges 27, 28 shown in FIG. 2 the perforating tools 38.1 for the delta fold or the perforating tool 36.1 for the second cross fold. These work with the stationary on the circumference 34 of the adjustable stored perforating cylinder 4 provided perforating strips 36.2 for the second Cross fold or 38.2 together for the delta fold.

Am Umfang 33, 34 der beiden Perforierzylinder 3, 4 stationär aufgenommen sind die Perforierwerkzeuge 35.1 und die damit zusammenarbeitende Perforierleiste 35.2 für die Ausbildung einer Perforation im Bereich eines ersten Querfalzes am Exemplar. Stationär am festgelagerten Perforierzylinder 3 ist die Perforierleiste 37.2, die ihrerseits mit dem an der weiteren Perforierbrücke 28 aufgenommenen Perforierleiste 37.1 für den zweiten Querfalz zusammenarbeitet. Der Perforierzylinder 3 rotiert in Drehrichtung 29 bezogen auf den Perforierspalt 26, während der verstellbar gelagerte Perforierzylinder 4 gleichsinnig zu diesem rotiert, so daß sich ein kontinuierlicher Bahnvorschub durch den Perforierspalt 26 einstellt. Die Perforierbrücke 28 ist bezogen auf die Umfangsfläche 34 des Perforierzylinders 4 entgegen der Drehrichtung des Perforierzylinders 4 in Drehrichtung 30 verstellbar.On the circumference 33, 34 of the two perforating cylinders 3, 4 are the stationary Perforating tools 35.1 and the cooperating perforating bar 35.2 for the Formation of a perforation in the area of a first transverse fold on the copy. Stationary on the fixed perforating cylinder 3 is the perforating bar 37.2, which in turn with the of the further perforating bridge 28 incorporated perforating strip 37.1 for the second Cross fold works together. The perforating cylinder 3 rotates in the direction of rotation 29 in relation to the perforating gap 26, while the adjustable perforating cylinder 4 rotates in the same direction, so that there is a continuous path feed through the perforation gap 26. The Perforating bridge 28 is opposed to the circumferential surface 34 of the perforating cylinder 4 the direction of rotation of the perforating cylinder 4 is adjustable in the direction of rotation 30.

Die hier stationär angeordnet wiedergegebenen Perforierleisten 36.2, 37.2 sowie 38.2 könnten (vgl. Fig. 2) auch am weiteren die Umfangsflächen 33, 34 der Perforierzylinder 3, 4 schalenartig umgreifenden Perforierbrücken 27.1, 28.1 (Fig. 4) aufgenommen werden und damit ebenfalls relativ verstellbar sein oder alternativ verstellbar sein, simultan mit Perforierwerkzeugen 36.1, 37.1, 38.1, die an den Perforierbrücken 27, 28 aufgenommen sind.The perforating strips 36.2, 37.2 and 38.2 shown here arranged in a stationary manner could (see FIG. 2) also the peripheral surfaces 33, 34 of the perforating cylinders 3, 4 perforating bridges 27.1, 28.1 (FIG. 4) encompassing the shell and thus also be relatively adjustable or alternatively be adjustable simultaneously with Perforating tools 36.1, 37.1, 38.1, which are added to the perforating bridges 27, 28 are.

Fig. 3 zeigt stark schematisiert eine Antriebskonfiguration für die die Perforierzylinder 3, 4 schalenartig umgreifenden Perforierbrücken 27, 28.3 shows a highly schematic drive configuration for the perforating cylinders 3, 4 perforated bridges 27, 28 encompassing the shell.

In der Ausführungsvariante gemäß Fig. 3 ist ein Perforierzylinder 3, 4 jeweils mit einer Perforierbrücke 27, 28 versehen. Die Perforierbrücken 27, 28 sind in Lagerungen 43, 44 auf Zylinderzapfen der Zylinderachsen 31, 32 aufgenommen und mit einer eine Verstellung in Umfangsrichtung der Perforierzylinder 3 und 4 ermöglichenden Verzahnung 47 versehen. Diese kämmt mit einer Außenverzahnung 46 eines Übertragungselements 45, welches als ein auf der Zylinderachse 31 bzw. 32 verschiebbare oder verdrehbare Kulissenführung ausgebildet werden kann.3 is a perforating cylinder 3, 4 each with a Perforating bridge 27, 28 provided. The perforating bridges 27, 28 are in bearings 43, 44 recorded on cylinder pins of the cylinder axes 31, 32 and with a Enabling adjustment in the circumferential direction of the perforating cylinders 3 and 4 Tooth 47 provided. This meshes with an external toothing 46 one Transmission element 45, which as a displaceable on the cylinder axis 31 or 32 or rotatable link guide can be formed.

Beide Kulissenführungen 45 auf den Zylinderachsen 31, 32 sind mit einer Verstelleinheit 48 verbunden, mit der eine Relativverstellung der Perforierbrücken 27, 28 zu den Umfangsflächen 33, 34 der Perforierzylinder 3, 4 erfolgen kann. Durch die Integration einer Ausgleichseinheit 49 in die Gleitführung 50 zwischen den Übertragungselementen 45 auf den Zylinderachsen 31, 32 läßt sich eine Veränderung des Perforierspaltes 26 unabhängig von der Phasenlagenverstellung der Perforierbrücken 27, 28 an den Perforierzylindern 3 und 4 zueinander erzielen. Dies wird dadurch unterstützt, daß der verstellbare Perforierzylinder 4 über eine Gelenkwelle 42 mit seinem Antriebszahnrad 41 verbunden ist, welches seinerseits über das Antriebszahnrad 40 des Perforierzylinders 3 angetrieben wird. Angesichts der Gelenkwelle 42 kann eine Relativverstellung des verstellbaren Zylinders 4 in Bezug auf den Perforierspalt 26 problemlos erfolgen. Die miteinander via Gleitführung 50 und Ausgleichseinheit 49 verbundenen Kulissenführungen 45 sind gemeinsam zueinander positionierbar, da eine korrekte Einstellung von Perforierwerkzeugen 36.1, 38.1 zu den Perforierleisten 36.2, 38.2 je nach Falzmodus gewährleistet sein muß. Erfolgt eine Verstellung der Drehlage einer Perforierbrücke, wird die dazu korrespondierende Perforierleisten aufnehmende Perforierbrücke falzmodusabhängig automatisch mitverstellt.Both link guides 45 on the cylinder axes 31, 32 are with an adjustment unit 48 connected with which a relative adjustment of the perforating bridges 27, 28 to the Circumferential surfaces 33, 34 of the perforating cylinders 3, 4 can take place. Through integration a compensation unit 49 in the sliding guide 50 between the transmission elements 45 A change in the perforation gap 26 can be made on the cylinder axes 31, 32 regardless of the phasing of the perforating bridges 27, 28 on the Achieve perforating cylinders 3 and 4 to each other. This is supported by the fact that the adjustable perforating cylinder 4 via a drive shaft 42 with its drive gear 41 which is in turn connected via the drive gear 40 of the perforating cylinder 3 is driven. In view of the propeller shaft 42, a relative adjustment of the adjustable cylinder 4 with respect to the perforating gap 26 can be done easily. The Link guides connected to one another via slide guide 50 and compensation unit 49 45 can be positioned together in relation to each other, since a correct setting of Perforating tools 36.1, 38.1 to the perforating strips 36.2, 38.2 depending on the folding mode must be guaranteed. If the rotational position of a perforating bridge is adjusted, the perforating bridge corresponding to the perforating bars automatically adjusted depending on the folding mode.

Fig. 4 zeigt die Kinematik eines Perforierzylinderpaares, wobei an jedem der Zylinder 3, 4 zwei Perforierbrücken 27, 27.1 bzw. 28, 28.1 ausgebildet sind. Die Perforierbrücken 27, 27.1, 28 und 28.1 sind allesamt in Lagerungen 43, 44 bzw. 54, 55 an den Zylinderachsen 31, 32 aufgenommen. Im Unterschied zum Ausführungsbeispiel gemäß Fig. 3 befinden sich an den hier dargestellten Übertragungselementen 51 zwei Außenverzahnungen 46, 52, die mit jeweils korrespondierenden Verzahnungen 47, 53 der Perforierbrücken 27, 27.1 sowie 28 und 28.1 zusammenarbeiten.4 shows the kinematics of a pair of perforating cylinders, with each of the cylinders 3, 4 two perforating bridges 27, 27.1 and 28, 28.1 are formed. The perforating bridges 27, 27.1, 28 and 28.1 are all in bearings 43, 44 and 54, 55 on the cylinder axes 31, 32 added. In contrast to the embodiment shown in FIG. 3 two external gears 46, 52, the respective toothings 47, 53 of the perforating bridges 27, 27.1 as well as 28 and 28.1 work together.

Es ist eine beiden Kulissenführungen zugeordnete Verstelleinheit 48 analog zur Ausführungsform gemäß Fig. 3 vorgesehen, die auf die Übertragungselemente 51 einwirkt, die sie gemeinsam verstellt, wobei ein oben bereits im Zusammenhang mit Fig. 3 beschriebene Ausgleichseinheit 49 in die Gleitführung 50 integriert ist.It is an adjustment unit 48 assigned to both link guides analogous to 3 provided, which acts on the transmission elements 51, which it adjusts together, one already above in connection with FIG. 3 Compensation unit 49 described is integrated into the slide guide 50.

Beim Ausführungsbeispiel gemäß Fig. 4 sind die in Fig. 2 stationär am Umfang 33, 34 der Perforierzylinder 3, 4 aufgenommenen Perforierleisten 36.2, 37.2 und 38.2 ebenfalls auf Perforierbrücken 27.1, 28.1 gelagert, so daß diese ebenfalls relativ zu den Umfangsflächen der Perforierzylinder 3, 4 in Umfangsrichtung verstellbar sind, so daß eine gleichzeitige Bewegung der Perforierleisten 36.2, 37.2, 38.2 und der Perforierwerkzeuge 36.1, 37.1 und 38.1 möglich ist. In the exemplary embodiment according to FIG. 4, those in FIG. 2 are stationary on the circumference 33, 34 of the Perforating cylinders 3, 4 also include perforated strips 36.2, 37.2 and 38.2 Perforating bridges 27.1, 28.1 are mounted so that they are also relative to the peripheral surfaces the perforating cylinder 3, 4 are adjustable in the circumferential direction, so that a simultaneous Movement of the perforating strips 36.2, 37.2, 38.2 and the perforating tools 36.1, 37.1 and 38.1 is possible.
