The third Knife holder 6 "is also offset in the direction of movement A of the material web 1 with respect to the other knife holders 6 and 6 'The third knife holder 6" is rotatably mounted in its own, second bearing unit 13, in a direction C perpendicular to the direction of movement A of the web 1 and parallel to the direction B of the first bearing unit 11 extends, is displaced back and forth. The second bearing unit 13 is guided together with the first bearing unit 11 in the stationary guide unit 12 'and can be moved in this independently of the first bearing unit 11.

Wie die Fig. 7 zeigt, dient der Messerhalter 6" zum Querperforieren des Materialbahnabschnitts 1a, während die andern Messerhalter 6 und 6' dazu bestimmt sind, in den Materialbahnabschnitten 1b bzw. 1c Querperforationslinien anzubringen.As the Fig. 7 shows the knife holder 6 "for transverse perforation of the web portion 1a, while the other knife holders 6 and 6 'are intended to attach in the web portions 1b and 1c transverse perforation lines.

An Hand der Fig. 8 - 13 wird nun erläutert, wie die in diesen Fig. 8 - 13 nicht dargestellte erste Lagereinheit 11 und mit dieser die Messerhalter 6, 6' in Verschieberichtung B dieser ersten Lagereinheit 11 in Abhängigkeit von der Breite der zu bearbeitenden Materialbahn 1 und deren seitlichen Ausrichtung (siehe Fig. 1) verstellt werden müssen, damit die Querperforationen in den Materialbahnabschnitten 1a, 1b immer lagerichtig erzeugt werden. In den Fig. 8 - 13 sind die Messerhalter 6, 6' in der jeweiligen Arbeitsposition gezeigt, in der sie auf die Trennlinie 5 zwischen den beiden Materialbahnabschnitten 1a, 1b ausgerichtet sind.Based on Fig. 8 - 13 will now explain how in this Fig. 8 - 13 not shown first bearing unit 11 and with this the knife holder 6, 6 'in the direction B of this first bearing unit 11 in response to the width of the material to be processed web 1 and the lateral orientation (see Fig. 1 ) must be adjusted so that the transverse perforations in the material web sections 1a, 1b are always generated in the correct position. In the Fig. 8 - 13 the knife holders 6, 6 'are shown in the respective working position, in which they are aligned with the dividing line 5 between the two material web sections 1a, 1b.

In den Fig. 8 und 9 ist die Situation gezeigt, in der die Materialbahn 1 auf die linke Referenz- oder Fixkante 4 ausgerichtet durch die Querperforationseinrichtung läuft.In the 8 and 9 the situation is shown in which the web 1 runs on the left reference or fixed edge 4 aligned by the Querperforationseinrichtung.

In Fig. 8 ist eine Materialbahn 1 von minimaler Breite, in Fig. 9 eine Materialbahn 1 von maximaler Breite gezeigt. In beiden Situationen sind die Messerhalter 6, 6' in ihrer Arbeitsposition wie bereits erwähnt auf die Trennlinie 5 ausgerichtet. Es ist ohne Weiteres ersichtlich, dass bei einer Umstellung von der in Fig. 8 gezeigten Betriebsweise auf die Betriebsweise nach Fig. 9 die Messerhalter 6, 6' mittels der Lagereinheit 11 in Richtung des Pfeiles B verschoben werden müssen; im gezeigten Beispiel so, dass das dem Lager 8 zugeordnete Ende des linken Messerhalters 6 zur linken Fixkante 4 hin und der andere Messerhalter 6' von der linken Fixkante 4 weiter weg bewegt wird.In Fig. 8 is a material web 1 of minimum width, in Fig. 9 shown a material web 1 of maximum width. In both situations, the knife holder 6, 6 'in its working position as already mentioned aligned on the dividing line 5. It is readily apparent that when switching from the in Fig. 8 shown operation on the operation after Fig. 9 the knife holder 6, 6 'must be moved by means of the bearing unit 11 in the direction of arrow B; in the example shown so that the bearing 8 associated end of the left knife holder 6 to the left fixed edge 4 and the other blade holder 6 'from the left fixed edge 4 is moved further away.

In den Fig. 10 und 11 ist in einer den Fig. 8 und 9 entsprechenden Weise die Situation gezeigt, in der die Materialbahn 1 auf die rechte Referenz- oder Fixkante 3 ausgerichtet durch die Querperforationseinrichtung läuft. Aus diesen Fig. 10 und 11 geht hervor, dass bei einer Umstellung von der in Fig. 10 gezeigten Betriebsweise (minimale Materialbahnbreite) auf die Betriebsweise nach Fig. 11 (maximale Materialbahnbreite) die Messerhalter 6, 6' mittels der Lagereinheit 11 in Richtung des Pfeiles B (entgegengesetzt zur Richtung des Pfeiles B der Fig. 9) verschoben werden müssen; im gezeigten Beispiel so, dass das dem Lager 8 zugeordnete Ende des rechten Messerhalters 6' zur rechten Fixkante 3 hin und der andere Messerhalter 6 von der rechten Fixkante 3 weiter weg bewegt wird.In the 10 and 11 is in a 8 and 9 corresponding manner shown the situation in which the web 1 runs on the right reference or fixed edge 3 aligned by the Querperforationseinrichtung. From these 10 and 11 shows that when switching from the in Fig. 10 shown operation (minimum web width) on the operation after Fig. 11 (maximum web width) the knife holder 6, 6 'by means of the bearing unit 11 in the direction of arrow B (opposite to the direction of the arrow B of Fig. 9 ) must be moved; in the example shown so that the bearing 8 associated end of the right knife holder 6 'to the right fixed edge 3 and the other blade holder 6 is moved from the right fixed edge 3 farther away.

In den Fig. 12 und 13 ist in einer den Fig. 8 und 9 entsprechenden Weise die Situation gezeigt, in der die Materialbahn 1 mittig zentriert durch die Querperforationseinrichtung läuft. In diesem Fall ist es nicht erforderlich, die Messerhalter 6, 6' zu verstellen.In the FIGS. 12 and 13 is in a 8 and 9 corresponding manner shown the situation in which the web 1 centered centered by the Querperforationseinrichtung runs. In this case it is not necessary to adjust the knife holders 6, 6 '.

An Hand der Fig. 14 - 19 wird nun erläutert, wie die in diesen Fig. 14 - 19 nicht dargestellten Lagereinheiten 11 und 13 mit den Messerhaltern 6, 6' und 6" in Verschieberichtung B der ersten Lagereinheit 11 bzw. in Verschieberichtung C der zweiten Lagereinheit 13 in Abhängigkeit von der Breite der zu bearbeitenden Materialbahn 1 und deren seitlichen Ausrichtung (siehe Fig. 1) verstellt werden müssen, damit die Querperforationen in den drei Materialbahnabschnitten 1a, 1b, 1c immer lagerichtig erzeugt werden. In den Fig. 14 -19 sind die Messerhalter 6, 6', 6" in der jeweiligen Arbeitsposition gezeigt, in der sie auf die Trennlinie 14 bzw. 15 zwischen den drei Materialbahnabschnitten 1a, 1b, 1c ausgerichtet sind.Based on Fig. 14 - 19 will now explain how in this Fig. 14 - 19 Not shown bearing units 11 and 13 with the knife holders 6, 6 'and 6 "in the direction B of the first bearing unit 11 and in the direction of displacement C of the second bearing unit 13 in dependence on the width of the material web to be processed 1 and the lateral alignment (see Fig. 1 ) must be adjusted so that the transverse perforations in the three material web sections 1a, 1b, 1c are always generated in the correct position. In the Fig. 14 -19 the knife holders 6, 6 ', 6 "are shown in the respective working position, in which they are aligned with the dividing line 14 or 15 between the three material web sections 1a, 1b, 1c.

In den Fig. 14 und 15 ist die Situation gezeigt, in der die Materialbahn 1 auf die linke Referenz- oder Fixkante 4 ausgerichtet durch die Querperforationseinrichtung läuft. In Fig. 14 ist eine Materialbahn 1 von minimaler Breite, in Fig. 15 eine Materialbahn 1 von maximaler Breite gezeigt. In beiden Situationen sind die Messerhalter 6, 6', 6" in ihrer Arbeitsposition wie bereits erwähnt auf die Trennlinie 14 bzw. 15 ausgerichtet. Bei einer Umstellung von der in Fig. 14 gezeigten Betriebsweise auf die Betriebsweise nach Fig. 15 müssen die Messerhalter 6, 6' und 6" mittels der Lagereinheiten 11, 13 in Richtung des Pfeiles B bzw. C verschoben werden; im gezeigten Beispiel so, dass das dem Lager 8 zugeordnete Ende des linken Messerhalters 6' zur linken Fixkante 4 hin und die beiden andern Messerhalter 6, 6" von der linken Fixkante 4 weiter weg bewegt werden.In the FIGS. 14 and 15 the situation is shown in which the web 1 runs on the left reference or fixed edge 4 aligned by the Querperforationseinrichtung. In Fig. 14 is a material web 1 of minimum width, in Fig. 15 shown a material web 1 of maximum width. In both situations, the knife holders 6, 6 ', 6 "in their working position, as already mentioned, are aligned with the dividing line 14 or 15. In the case of a changeover from the in Fig. 14 shown operation on the operation after Fig. 15 the knife holders 6, 6 'and 6 "must be displaced in the direction of arrow B or C by means of the bearing units 11, 13, in the example shown so that the end of the left knife holder 6' assigned to the bearing 8 moves towards the left fixed edge 4 and the two other knife holders 6, 6 "are moved further away from the left fixed edge 4.

In den Fig. 16 und 17 ist in einer den Fig. 14 und 15 entsprechenden Weise die Situation gezeigt, in der die Materialbahn 1 auf die rechte Referenz- oder Fixkante 3 ausgerichtet durch die Querperforationseinrichtung läuft. Aus diesen Fig. 16 und 17 geht hervor, dass bei einer Umstellung von der in Fig. 16 gezeigten Betriebsweise (minimale Materialbahnbreite) auf die Betriebsweise nach Fig. 17 (maximale Materialbahnbreite) die Messerhalter 6, 6', 6" mittels der Lagereinheiten 11, 13 in Richtung des Pfeiles B bzw. C (bezüglich des Pfeiles B bzw. C der Fig. 15 in entgegengesetzter Richtung) verschoben werden müssen; im gezeigten Beispiel so, dass das dem Lager 8 zugeordnete Ende des rechten Messerhalters 6' zur rechten Fixkante 3 hin und die beiden andern Messerhalter 6, 6' von der rechten Fixkante 3 weiter weg bewegt werden.In the FIGS. 16 and 17 is in a FIGS. 14 and 15 appropriate way the situation shown in the Material web 1 on the right reference or fixed edge 3 aligned by the Querperforationseinrichtung runs. From these FIGS. 16 and 17 shows that when switching from the in Fig. 16 shown operation (minimum web width) on the operation after Fig. 17 (maximum web width) the knife holder 6, 6 ', 6 "by means of the bearing units 11, 13 in the direction of arrow B and C (with respect to the arrow B and C of the Fig. 15 in the opposite direction); in the example shown so that the bearing 8 associated end of the right knife holder 6 'to the right fixed edge 3 and the other two knife holder 6, 6' are moved away from the right fixed edge 3 further away.

In den Fig. 18 und 19 ist in einer den Fig. 14 und 15 entsprechenden Weise die Situation gezeigt, in der die Materialbahn 1 mittig zentriert durch die Querperforationseinrichtung läuft. In diesem Fall müssen die Messerhalter 6 und 6' mittels der Lagereinheit 11 in Richtung des Pfeiles B zur linken Fixkante 4 hin und muss der Messerhalter 6" mittels der Lagereinheit 13 in Pfeilrichtung C zur rechten Fixkante 3 hin verschoben werden.In the FIGS. 18 and 19 is in a FIGS. 14 and 15 corresponding manner shown the situation in which the web 1 centered centered by the Querperforationseinrichtung runs. In this case, the knife holder 6 and 6 'by means of the bearing unit 11 in the direction of arrow B to the left fixed edge 4 and the knife holder 6 "must be moved by means of the bearing unit 13 in the direction of arrow C to the right fixed edge 3 out.

Aus den Fig. 14 - 19 ist weiter ersichtlich, dass für das Querperforieren des mittleren Materialbahnabschnitts 1b das Perforiermesser 7 desjenigen Messerhalters 6, der zum Querperforieren dieses mittleren Materialbahnabschnittes 1b dient, in seiner Länge der Breite des mittleren Materialbahnabschnitts 1b der jeweiligen Materialbahn 1 angepasst werden muss. So ist die Länge des Perforiermessers 7 des Messerhalters 6 bei den in den Fig. 15, 17 und 19 gezeigten Betriebszuständen länger als bei den Betriebszuständen nach den Fig. 14, 16 bzw. 18.From the Fig. 14 - 19 It can also be seen that, for the transverse perforation of the middle material web section 1b, the perforating blade 7 of that knife holder 6 which serves for transverse perforation of this middle material web section 1b must be adapted in its length to the width of the middle material web section 1b of the respective material web 1. Thus, the length of the Perforiermessers 7 of the knife holder 6 in the in the FIGS. 15, 17 and 19 shown operating conditions longer than in the operating conditions after the Fig. 14, 16 or 18.

Da wie beschrieben die Lagereinheit 11 bzw. die Lagereinheit 13 mit den Messerhaltern 6, 6' bzw. 6" mit verhältnismässig einfachen Mitteln quer zur Materialbahn 1 verstellt werden können, lassen sich die Umrüstzeiten verkürzen. Unter Umständen kann es zweckmässig sein, den dritten Messerhalter 6" zusammen mit den beiden andern Messerhaltern 6 und 6' in der ersten Lagereinheit 11 zu lagern. In diesem Fall entfällt die zweite Lagereinheit 13.Since, as described, the bearing unit 11 or the bearing unit 13 with the knife holders 6, 6 'or 6 "can be adjusted transversely to the material web 1 with relatively simple means, the changeover times can be shortened 6 "together with the other two knife holders 6 and 6 'in the first storage unit 11 to store. In this case, the second storage unit 13 is eliminated.

Bei den beschriebenen Konstruktionen können kleine, individuell angetriebene Messerhalter 6 eingesetzt werden, wodurch die anzutreibenden Massen klein gehalten werden können. Dies erlaubt im Betrieb eine grössere Dynamik.In the described constructions small, individually driven knife holder 6 can be used, whereby the masses to be driven can be kept small. This allows greater dynamics during operation.

Da die Messerhalter 6 in Bewegungsrichtung A der Materialbahn 1 gegeneinander versetzt in der Lagereinheit 11 gelagert sind, können die Messerhalter 6 so in einer sich quer zur Bewegungsrichtung A der Materialbahn 1 erstreckenden Richtung angeordnet werden, dass sie sich wie in den Figuren dargestellt in Bewegungsrichtung A der Materialbahn 1 gesehen überlappen Das erlaubt die Bearbeitung der Materialbahn 1 über deren ganze Breite. Somit bleiben keine unbearbeiteten Materialbahnabschnitte übrig.Since the knife holders 6 are mounted offset in the direction of movement A of the material web 1 in the storage unit 11, the knife holder 6 can be arranged in a direction transverse to the direction of movement A of the web 1 extending direction that they are as shown in the figures in the direction of movement A. overlapping the material web 1. This allows the processing of the material web 1 over its entire width. Thus, no unprocessed material web sections remain.

Auch bei einer Materialbahn, die nicht wie gezeigt in Materialbahnabschnitte unterteilt ist, ist es sinnvoll, den einzigen Messerhalter, der zur Querperforation benötigt wird, wie beschrieben seitlich verstellbar zu lagern. Auf diese Weise ist auch bei nur einem Messerhalter eine Anpassung dessen Arbeitsposition an verschiedene Breiten und verschiedene seitliche Ausrichtungen der zu bearbeitenden Materialbahnen möglich.Even with a material web, which is not divided into material web sections as shown, it makes sense to store the single knife holder, which is needed for transverse perforation, as described laterally adjustable. In this way, an adaptation of its working position to different widths and different lateral orientations of the material webs to be processed is possible even with only one knife holder.

Das vorstehend anhand von Messerhaltern 6, die mit Perforiermessern 7 versehenen sind, beschriebene Prinzip der seitlichen Verstellbarkeit der Messerhalter 6 eignet sich auch für Messerhalter, die mit Schneidmessern bestückt sind und zum Querschneiden von bewegten Materialbahnen eingesetzt werden.The principle of the lateral adjustability of the knife holder 6 described above with reference to knife holders 6 which are provided with perforating knives 7 is also suitable for knife holders which are equipped with cutting knives and are used for the transverse cutting of moving material webs.
