Abstract

The invention relates to a device for the transverse folding of webs from a rotary printing press to a third of the format length. A device is to be produced which yields products with external point spurs, but which does not have cylinders equipped with grippers and does not draw off long curved pieces from cylinders against the direction of rotation of the latter. To this end, a web (17) is cut by means of a cutting cylinder (1) correspondingly provided with two cutting blades (2; 3) and a point spur cylinder provided with pairs of point spur arrangements (5; 6) into sections (A; B) representing one third and two thirds of the format length. The said sections (A; B) are placed one on top of the other by means of a point spur cylinder (9) and are then provided with an initial transverse fold by means of a point spur and folding blade cylinder (10) and a folding jaw cylinder (14). The device permits a high operating speed. In addition, the point spurs of both sections (A; B) are on the outside, so that losses due to cutting are low. …<IMAGE>…

Description

Die Erfindung betrifft eine Vorrichtung zum Querfalzen von Bahnen einer Rotationsdruckmaschine nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for cross-folding webs of a rotary printing press according to the preamble of claim 1.

Auf ein Drittel der Formatlänge der Druckmaschine gefalzte Produkte werden vor allem in der Bücherproduktion weiterverarbeitet. Ein Falzapparat für derartige Produkte ist in EP-B1-19 202, Fig. 5, gezeigt. Danach wird die Bahn zwischen einem Messerzylinder und einem Punktur- und Falzmesserzylinder in Formatlänge geschnitten. Bei der anschließenden Übergabe in die Falzklappe eines Falzklappenzylinders wird der Bogen im Verhältnis 2/3 zu 1/3 gefalzt. Bei der danach erfolgenden Weitergabe in die Falzklappe eines weiteren Falzklappenzylinders erfolgt eine zweite Querfalzung auf ein Drittel der Formatlänge.Products folded to a third of the format length of the printing press are mainly processed in book production. A folder for such products is shown in EP-B1-19 202, Fig. 5. Then the web is cut between a knife cylinder and a puncture and folding knife cylinder in format length. During the subsequent transfer into the jaw of a jaw cylinder, the sheet is folded in a 2/3 to 1/3 ratio. When it is then passed on to the folding jaw of another folding jaw cylinder, a second transverse fold is made to a third of the format length.

Diese Vorrichtung zwar hat den Vorteil, daß die Punkturen außen liegen, somit mit Vorfalz gearbeitet werden und die bei Bücherproduktion geforderte Entfernung der Punkturen mit geringem Schnittverlust erfolgen kann. Die Vorrichtung ist aber mit dem Nachteil behaftet, daß bei der Bildung des ersten Querfalzes zwei Drittel des Bogens vom Punktur- und Falzmesserzylinder entgegen dessen Drehrichtung abgezogen werden müssen und dadurch die Arbeitsgeschwindigkeit der Falzvorrichtung begrenzt ist.This device has the advantage that the punctures are on the outside, so that a pre-fold is used and the removal of the punctures required in book production can be done with little loss of cut. The device has the disadvantage, however, that when the first transverse fold is formed, two thirds of the sheet must be drawn off from the puncturing and folding knife cylinder against the direction of rotation thereof, and the working speed of the folding device is thereby limited.

Es ist weiterhin eine Falzvorrichtung bekannt (Braun, Atlas des Zeitungs- und Illustrationsdruckes, Polygraph Verlag GmbH, Frankfurt am Main, 1960, S. 95), bei der Zwischen einem Messerzylinder und einem Punktur- und Falzmesserzylinder zunächst die Bahn in Formatlänge geschnitten wird. Bei entsprechender Anordnung der Arbeitselemente kann anschließend der Bogen bei der Übergabe in die Falzklappe eines Falzklappenzylinders auf zwei Drittel der Formatlänge gefalzt werden. Danach wird der Falzbogen in die Greifer eines Greifer- und Falzmesserzylinders übergeben. Bei der anschließenden Übergabe in eine Falzklappe des Falzklappenzylinders wird der Bogen auf ein Drittel der Formatlänge gefalzt.A folding device is also known (Braun, Atlas of Newspaper and Illustration Printing, Polygraph Verlag GmbH, Frankfurt am Main, 1960, p. 95), in which the web is first cut in format length between a knife cylinder and a puncturing and folding knife cylinder. If the working elements are arranged accordingly, the sheet can then be folded to two thirds of the format length when it is transferred to the folding jaw of a folding jaw cylinder. The folded sheet is then transferred to the grippers of a gripper and folding knife cylinder. In the Subsequent transfer into a folding jaw of the folding jaw cylinder, the sheet is folded to a third of the format length.

Die Vorrichtung vermeidet zwar das Abziehen von zwei Dritteln der Bogenlänge entgegen der Drehrichtung eines Zylinders, ist aber dennoch infolge Greifereinsatzes in der Arbeitsgeschwindigkeit begrenzt. Weiterhin liegen bei dem Falzprodukt die Punkturen innen, wodurch für deren Entfernung der Schnittverlust hoch ist.Although the device avoids pulling off two thirds of the arc length counter to the direction of rotation of a cylinder, it is nevertheless limited in working speed due to the use of the gripper. Furthermore, the punctures are on the inside of the folded product, which means that the cut loss is high for their removal.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Querfalzen von Bahnen einer Rotationsdruckmaschine auf ein Drittel der Formatlänge mit einem Messerzylinder, einem Punktur- und Falzmesserzylinder und einem Falzklappenzylinder zu schaffen, die Produkte mit außen liegenden Punkturen erstellt, dabei auf greiferbestückte Zylinder verzichtet und keine langen Bogenstücke von Zylindern entgegen deren Drehrichtung abzieht. Diese Aufgabe wird bei einer gattungsgemäßen Einrichtung durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst. Dadurch wird die Bahn im Verhältnis 1/3 zu 2/3 geschnitten, und anschließend werden die beiden Abschnitte aufeinandergelegt und mit einem Querfalz versehen. Dabei wird nur ein Drittel des Formatbogens entgegen der Drehbewegung von einem Zylinder abgezogen und somit eine hohe Arbeitsgeschwindigkeit der Falzvorrichtung ermöglicht. Weiterhin liegen die Punkturen beider Abschnitte außen und erlauben so deren verlustarmen Abschnitt.The invention has for its object to provide a device for cross-folding webs of a rotary printing press to a third of the format length with a knife cylinder, a puncturing and folding knife cylinder and a folding jaw cylinder, which creates products with external punctures, doing without gripper-equipped cylinders and none pulls long bends from cylinders against their direction of rotation. This object is achieved in a generic device by the characterizing features of claim 1. This cuts the web in a 1/3 to 2/3 ratio, and then the two sections are placed on top of one another and provided with a cross fold. In this case, only a third of the format sheet is pulled off a cylinder counter to the rotary movement, thus allowing the folding device to work at high speed. Furthermore, the punctures of both sections are on the outside and thus allow their low-loss section.

Die Aufgabe wird ebenfalls durch die kennzeichnenden Merkmale des Anspruchs 4 gelöst. Hierbei wird die Bahn zunächst in Formatbogen geschnitten. Diese werden anschließend im Verhältnis 1/3 zu 2/3 geteilt. Danach werden die beiden Abschnitte aufeinandergelegt und mit einem Querfalz versehen. Dabei werden auch hier alle bereits weiter oben genannten Vorteile erzielt.The object is also achieved by the characterizing features of claim 4. The web is first cut into format sheets. These are then divided in a 1/3 to 2/3 ratio. Then the two sections are placed on top of each other and provided with a cross fold. Here, too, all the advantages already mentioned above are achieved.

Der Vorfalz ist vorteilhaft einstellbar bei Anwendung der kennzeichnenden Merkmale der Ansprüche 2 und 3 bzw. 5.The pre-fold is advantageously adjustable when using the characterizing features of claims 2 and 3 or 5.

Ihnen sind Schneidnuten 7; 8 zugeordnet. Am Punkturzylinder 4 sind in dessen Drehrichtung nach dein Messerzylinder 1 nacheinander ein weiterer Punkturzylinder 9 und ein Punktur- und Falzmesserzylinder 10 angeordnet. Der Punkturzylinder 9 trägt vier Punktursysteme 11 mit jeweils einem Abstand von einem Drittel der Formatlänge zueinander. Der Punktur- und Falzmesserzylinder 10 hat den doppelten Umfang des Messerzylinders 1 und ist mit je zwei Punktursystemen 12 und Falzmessern 13 besetzt, wobei letztere zum jeweils in Drehrichtung benachbarten Punktursystem einen Umfangsabstand von einem Drittel der Formatlänge haben. Dem Punktur- und Falzmesserzylinder 10 schließt sich ein Falzklappenzylinder 14 mit zwei Falzklappen 15 auf einem zwei Formatlängen umfassenden Umfang an.The transverse folding device shown in Fig. 1 contains a knife cylinder 1 with a circumference in the size of the format length. It is equipped with two cutting blades 2; 3 with a circumferential distance of one third of the format length. The knife cylinder 1 works together with a puncture cylinder 4, which has three times the circumference of the knife cylinder 1 and three pairs of puncture systems 5; 6 contains, the latter each having a circumferential distance of one third of the format length. You are cutting grooves 7; 8 assigned. A further puncture cylinder 9 and a puncture and folding knife cylinder 10 are arranged one after the other on the puncture cylinder 4 in the direction of rotation thereof according to the knife cylinder 1. The puncture cylinder 9 carries four puncture systems 11, each at a distance of one third of the format length from one another. The puncture and folding knife cylinder 10 has twice the circumference of the knife cylinder 1 and is equipped with two puncture systems 12 and folding knives 13, the latter having a circumferential distance of one third of the format length from the puncture system adjacent in the direction of rotation. The puncture and folding knife cylinder 10 is followed by a folding jaw cylinder 14 with two folding jaws 15 on a circumference comprising two format lengths.

Die mittels eines Falztrichters 16 z.B. einmal längsgefalzte Bahn 17 wird über Zugwalzen 18 der Querfalzvorrichtung zugeführt. Dabei wird die Bahn 17 in der Zentralen des Messerzylinders 1 und des Punkturzylinders 4 von den Schneidmessern 2 und 3 in Verbindung mit den Schneidnuten 7 und 8 in die Abschnitte A und B mit Längen von einem Drittel und zwei Dritteln der Formatlänge geschnitten. Diese werden von den Punktursystemen 5 und 6 des Punkturzylinders 4 aufgenadelt. Bei dessen Weiterdrehung werden in der Zentralen zum Punkturzylinder 9 die Abschnitte A von den Punktursystemen 11 des Punkturzylinders 9 übernommen. Letzterer gibt bei seiner nächsten Umdrehung die Abschnitte A wieder an den Punkturzylinder 4 ab, wobei diese von den Punktursystemen 6 übernommen werden und auf den Abschnitten B zu liegen kommen. In der Zentralen des Punkturzylinders 4 und des Punktur- und Falzmesserzylinders 10 werden die Abschnitte A und B von den Punktursystemen 12 übernommen. Nach Drehung des Punktur- und Falzmesserzylinders 10 werden in der Zentralen zum Falzklappenzylinder 14 die Abschnitte A und B mittels der Falzmesser 13 in die Falzklappen 15 gedrückt und dabei mit einem ersten Querfalz versehen. Der Abschnitt A ist jetzt in den Abschnitt B eingewickelt, und die Punkturen 19 des fertigen Produktes 20 (Fig. 2) liegen außen. Der Vorfalz 21 kann durch Verstellen der Schneidmesser 2; 3, Punktursysteme 5; 6 und Falzmesser 13 und Punktursysteme 12 zueinander eingestellt werden.

The web 17 is cut in the center of the knife cylinder 1 and the puncture cylinder 4 by the cutting knives 2 and 3 in conjunction with the cutting grooves 7 and 8 in the sections A and B with lengths of one third and two thirds of the format length. These are needled by the puncture systems 5 and 6 of the puncture cylinder 4. As it continues to rotate, sections A are taken over by the puncture systems 11 of the puncture cylinder 9 in the center of the puncture cylinder 9. The latter delivers the sections A again to the puncture cylinder 4 during its next rotation, these being taken over by the puncture systems 6 and coming to rest on the sections B. In the center of the puncture cylinder 4 and the puncture and folding knife cylinder 10, the sections A and B are taken over by the puncture systems 12. After rotation of the puncture and folding knife cylinder 10, sections A and B in the center of the folding jaw cylinder 14 are pressed into the folding jaws 15 by means of the folding knife 13 and thereby provided with a first transverse fold. Section A is now wrapped in section B and the punctures 19 of the finished product 20 (FIG. 2) are on the outside. The pre-fold 21 can be adjusted by adjusting the cutting knife 2; 3, point systems 5; 6 and folding knife 13 and puncture systems 12 can be adjusted to each other. The folded product 20 can be fed to a bucket wheel boom 23 via a control system 22 or to a second longitudinal folding device 25 by means of a belt line system 24.

Fig. 3 zeigt eine Querfalzvorrichtung mit einem Messerzylinder 26 mit einem Umfang in der Größe der Formatlänge. Er ist mit einem Schneidmesser 27 ausgestattet und arbeitet mit einem Punktur- und Messerzylinder 28 zusammen. Dieser weist den dreifachen Umfang des Messerzylinders 26 auf und enthält je drei Schneidmesser 29 und Punktursysteme 30, wobei letztere zum jeweils in Drehrichtung benachbarten Schneidmesser 29 einen Umfangsabstand von einem Drittel der Formatlänge haben. Den Punktursystemen 30 sind Schneidnuten 31 zugeordnet. Am Punktur- und Messerzylinder 28 sind in dessen Drehrichtung nach dem Messerzylinder 26 nacheinander ein Punkturzylinder 32 und ein Punktur- und Falzmesserzylinder 33 angeordnet. Der Punkturzylinder 32 trägt vier Punktursysteme 34 mit jeweils einem Abstand von einem Drittel der Formatlänge zueinander. Ihnen sind Schneidnuten 35 zugeordnet. Der Punktur- und Falzmesserzylinder 33 hat den doppelten Umfang des Messerzylinders 26 und ist mit je zwei Punktursystemen 36 und Falzmessern 37 besetzt, wobei letztere zum jeweils in Drehrichtung benachbarten Punktursystem 36 einen Umfangsabstand von einem Drittel der Formatlänge haben. Dem Punktur- und Falzmesserzylinder 33 schließt sich ein Falzklappenzylinder 38 an, der einen Umfang von zwei Formatlängen aufweist und zwei Falzklappen 39 trägt.Fig. 3 shows a transverse folding device with a knife cylinder 26 with a circumference in the size of the format length. It is equipped with a cutting knife 27 and works with a puncture and knife cylinder 28. This has three times the circumference of the knife cylinder 26 and contains three cutting knives 29 and puncture systems 30, the latter having a circumferential distance of one third of the format length from the cutting knife 29 which is adjacent in the direction of rotation. Cutting grooves 31 are assigned to the puncture systems 30. On the puncture and knife cylinder 28 are in it Direction of rotation after the knife cylinder 26 a puncture cylinder 32 and a puncture and folding knife cylinder 33 are arranged in succession. The puncture cylinder 32 carries four puncture systems 34, each at a distance of one third of the format length from one another. They are assigned cutting grooves 35. The puncturing and folding knife cylinder 33 has twice the circumference of the knife cylinder 26 and is equipped with two puncture systems 36 and folding knives 37, the latter having a circumferential distance of one third of the format length from the puncturing system 36 which is adjacent in the direction of rotation. The puncture and folding knife cylinder 33 is followed by a folding jaw cylinder 38, which has a circumference of two format lengths and carries two folding jaws 39.

Die mittels eines Falztrichters 40 z.B. einmal längsgefalzte Bahn 41 wird über die Zugwalzen 42 der Querfalzvorrichtung zugeführt. Dabei wird die Bahn 41 in der Zentralen des Messerzylinders 26 und des Punktur- und Messerzylinders 28 in Bogen mit der Formatlänge geschnitten. Die Bogen werden auf die Punktursysteme 30 genadelt und bei der weiteren Drehung des Punktur- und Messerzylinders 28 in der Zentralen mit dem Punkturzylinder 32 mittels der Schneidmesser 29 und der Schneidnuten 35 in Abschnitte A und B mit Längen von einem Drittel und zwei Dritteln der Formatlänge geschnitten. Während die Abschnitte A mittels der Punktursysteme 34 vom Punkturzylinder 32 übernommen werden, verbleiben die Abschnitte B auf dem Punktur- und Messerzylinder 28. Der Punkturzylinder 32 gibt bei seiner nächsten Umdrehung die Abschnitte A wieder an den Punktur- und Messerzylinder 28 ab, wobei diese von den Punktursystemen 30 übernommen werden und auf den Abschnitten B zu liegen kommen. In der Zentralen des Punktur- und Messerzylinders 28 und des Punktur- und Falzmesserzylinders 33 werden die Abschnitte A und B von den Punktursystemen 36 übernommen. Nach Drehung des Punktur- und Falzmesserzylinders 33 werden in der Zentralen zum Falzklappenzylinder 38 die Abschnitte A und B mittels der Falzmesser 37 in die Falzklappen 39 gedrückt und so mit einem ersten Querfalz versehen. Es entsteht somit das in Fig. 2 gezeigte Produkt 20. Der Vorfalz 21 kann durch Verstellen der Schneidmesser 29 und der Punktursysteme 30 bzw. der Falzmesser 37 und der Punktursysteme 36 zueinander eingestellt werden. Das gefalzte Produkt 20 kann wiederum über ein Leitsystem 43 einem Schaufelradausleger 44 oder mittels eines Bandleitungssystemes 45 einer zweiten Längsfalzeinrichtung 46 zugeführt werden.The web 41, which has been folded longitudinally once by means of a folding former 40, is fed to the transverse folding device via the pull rollers 42. The web 41 is cut in the center of the knife cylinder 26 and the puncturing and knife cylinder 28 into sheets with the format length. The sheets are needled onto the puncture systems 30 and, during further rotation of the puncture and knife cylinder 28 in the center with the puncture cylinder 32 by means of the cutting knives 29 and the cutting grooves 35, cut into sections A and B with lengths of one third and two thirds of the format length . While the sections A are taken over by the puncture systems 34 by means of the puncture systems 34, the sections B remain on the puncture and knife cylinder 28. The puncture cylinder 32 delivers the sections A again to the puncture and knife cylinder 28 during its next rotation, whereby these pass from the point systems 30 are taken over and come to rest on the sections B. In the center of the puncture and knife cylinder 28 and the puncture and folding knife cylinder 33, sections A and B are taken over by the puncture systems 36. After rotation of the puncture and folding knife cylinder 33, sections A and B in the center of the folding jaw cylinder 38 are pressed into the folding jaws 39 by means of the folding knife 37 and thus provided with a first transverse fold. The result is the product 20 shown in FIG. 2. The pre-fold 21 can be adjusted by adjusting the cutting knives 29 and the puncture systems 30 or the folding knife 37 and the puncture systems 36 can be adjusted to one another. The folded product 20 can in turn be fed to a bucket wheel boom 44 via a control system 43 or to a second longitudinal folding device 46 by means of a belt line system 45.
