Abstract

Zur Erzeugung einer Querfalzperforierung am Falzrücken des zweiten Querfalzes sind die Falzmesser (13) eines Greifer- und Falzmesserzylinders (11) als Perforiermesser ausgebildet und gegen eine Perforiernut (10) am Falzklappenzylinder (8) steuerbar. Die so perforierten Falzprodukte werden anschließend durch die Falzmesser (13) in Falzklappen (16) eines nachgeordneten Greifer- und Falzklappenzylinders (14) gestoßen, wodurch der zweite Querfalz erzeugt wird. Sollen die Produkte ohne zweiten Querfalz ausgelegt werden, so erfolgt deren Obernahme von dem Greifer- und Falzmesserzylinder (11) auf dem Greifer- und Falzklappenzylinder (14) durch an letzterem angeordnete Greifer (15). Bei dieser Betriebsweise sind die Falzklappen (14) und die Perforiermesser (13) außer Funktion. Durch entsprechende Ausbildung des Punktur- und Falzmesserzylinders (5) ist auch ein Sammeln der Exemplare vor der Erzeugung des ersten Querfalzes möglich.

To produce a transverse fold perforation on the fold back of the second transverse fold, the folding knives (13) of a gripper and folding knife cylinder (11) are designed as perforating knives and can be controlled against a perforating groove (10) on the folding jaw cylinder (8). The folding products perforated in this way are then pushed through the folding blades (13) into folding jaws (16) of a downstream gripper and folding jaw cylinder (14), whereby the second transverse fold is produced. If the products are to be designed without a second transverse fold, they are taken over by the gripper and folding knife cylinder (11) on the gripper and folding jaw cylinder (14) by grippers (15) arranged on the latter. In this mode of operation, the jaws (14) and the perforating knives (13) are out of function. By appropriately designing the puncture and folding knife cylinder (5), it is also possible to collect the copies before the first transverse fold is produced.

Description

Die Erfindung betrifft einen Falzapparat mit einer Vorrichtung zum Querperforieren am Falzrücken von Falzexemplaren, bei denen die Perforation vor dem Falzen an dem Falzprodukt angebracht wird.The invention relates to a folding device with a device for transverse perforation on the fold back of fold copies, in which the perforation is applied to the fold product before folding.

Aus der DE-AS 1 932 241 ist ein Falzwerk mit einer Vorrichtung zum Querfalzperforieren am Falzrücken von Falzexemplaren bekannt, bei denen die Perforation vor dem Falzen an den Bogen angebracht wird. Die Falzmesser sind mit Perforationszähnen ausgestattet und an dem Sammelzylinder ist eine Gegenwalze 2 mit einer Perforiernut angestellt. Abgesehen davon, daß die zusätzliche Verwendung der Gegenwalze mit Kosten verbunden ist und für diese zusätzlicher Raum beansprucht wird, was dem Wunsch nach kompakt bauenden Falzapparaten entgegensteht, ist mit diesem bekannten Falzwerk nur die Erzeugung einer Querperforierung am Falzrücken des ersten Querfalzes möglich.From DE-AS 1 932 241 a folding mechanism with a device for transverse fold perforation on the fold back of fold copies is known, in which the perforation is applied to the sheet before folding. The folding knives are equipped with perforation teeth and a counter roller 2 with a perforation groove is attached to the collecting cylinder. Apart from the fact that the additional use of the counter roller is associated with costs and additional space is required for this, which is contrary to the desire for compact folding devices, with this known folding unit it is only possible to produce a transverse perforation on the fold back of the first transverse fold.

Hiervon ausgehend ist es die Aufgabe der Erfindung einen Falzapparat zu schaffen, der die einzelnen Lagen der Falzexemplare im zweiten Querfalz miteinander verbindet, wobei hierfür keine separaten Walzen bzw. Zylinder benötigt werden sollen. Diese Aufgabe wird durch die Anwendung der Merkmale des kennzeichnenden Teils des Anspruch 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen sowie aus der Beschreibung und der beiliegenden Zeichnung.Proceeding from this, it is the object of the invention to create a folding apparatus which connects the individual layers of the folding copies in the second transverse fold, with no separate rollers or cylinders being required for this. This object is achieved by applying the features of the characterizing part of claim 1. Advantageous developments of the invention result from the subclaims and from the description and the accompanying drawing.

Durch die Erfindung wird es in einfacher Weise möglich, die Lagen der Produkte im zweiten Querfalz miteinander zu verzahnen. Dies ist besonders von Vorteil, wenn die Falzexemplare als Buchsektionen hergestellt werden, die später einer Klebeverbindung zugeführt werden. Ebenso ist diese Art der Querperforationseinbringung vorteilhaft, wenn die in den Falzapparat einlaufenden Stränge nicht durch einen sogenannten Trichterfalz verbunden werden können. Bei allgemein bekannten Falzapparaten wurden sowohl die Querfalzperforierungen für den ersten als auch für den zweiten Falz am Strang, d.h. an der einlaufenden Bahn erzeugt, was verschiedene Nachteile u.a. bezüglich der Verarbeitungsgenauigkeiten mit sich brachte.The invention makes it possible in a simple manner to interlock the layers of the products in the second transverse fold. This is particularly advantageous if the folded copies are produced as book sections that are later fed to an adhesive connection. This type of cross perforation is likewise advantageous if the strands entering the folder cannot be connected by a so-called funnel fold. In the case of generally known folding apparatuses, both the transverse fold perforations for the first and for the second fold were produced on the strand, that is to say on the incoming web, which entailed various disadvantages, inter alia with regard to the processing accuracy.

Im folgenden wird die Erfindung unter Bezugnahme auf die beiliegende Zeichnung im einzelnen beschrieben. Eine oder mehrere übereinander liegende Bedruckstoffbahnen 1 werden über ein Zugwalzenpaar 2 einem Punktur- und Falzmesserzylinder 5 zugeführt, der mit Punkturen 6 und Falzmessern 7 ausgestattet ist. Die Bedruckstoffbahn 1 wird am Punktur- und Falzmesserzylinder 5 durch einen an diesen angestellten mit Messern 4 versehenen Messerzylinder 3 auf die gewünschte Produkt- bzw. Exemplarlänge zugeschnitten. Die Produktabschnitte werden mittels der Punkturen 6 des Punktur- und Falzmesserzylinders 5 teilweise um letzteren geführt. Durch die Falzmesser 7 werden die Falzexemplare in Falzklappen 9 eines an dem Punktur- und Falzklappenzylinder 5 angestellten Falzklappenzylinder 8 eingebracht, wodurch der erste Querfalz erzeugt wird. Der Falzklappenzylinder 8 ist sehr einfach aufgebaut und weist außer den erwähnten Falzklappen 9 lediglich noch eine Perforiernut 10 auf.In the following the invention is described in detail with reference to the accompanying drawing. One or more printing material webs 1 lying one above the other are fed via a pair of pull rollers 2 to a puncturing and folding knife cylinder 5 which is equipped with punctures 6 and folding knives 7. The printing material web 1 is cut to the desired product or specimen length on the puncturing and folding knife cylinder 5 by a knife cylinder 3 provided with knives 4 thereon. The product sections are partially guided around the latter by means of the punctures 6 of the puncturing and folding knife cylinder 5. The folding copies 7 insert the folding copies into folding jaws 9 of a folding jaw cylinder 8 positioned on the puncture and folding jaw cylinder 5, whereby the first transverse fold is produced. The folding jaw cylinder 8 is of a very simple construction and, in addition to the mentioned folding jaws 9, only has one perforating groove 10.

Hinter dem Falzklappenzylinder 8 ist ein Greifer- und Falzmesserzylinder 11 angeordnet, der Greifer 12 und Falzmesser 13 aufweist. Mit Hilfe der Greifer werden die auf dem Falzklappenzylinder 8 aufliegenden bereits einmal quergefalzten Exemplare auf den Greifer- und Falzmesserzylinder 11 übernommen. Nun erfolgt in erfindungsgemäßer Weise die Erzeugung einer Querperforation am Falzrücken vor dem anschließend zu erzeugenden zweiten Querfalz. Dies geschieht dadurch, daß die als Perforiermesser ausgebildeten Falzmesser 13 des Greifer- und Falzmesserzylinders 11 gegen die Perforiernut 10 des Falzklappenzylinders 8 gesteuert werden, wodurch die Perforation an dem auf dem Greifer- und Falzklappenzylinder aufliegenden Exemplar erzeugt wird. Anschließend wird der zweite Querfalz erzeugt, in dem die Falzmesser 13 die auf dem Greifer- und Falzmesserzylinder 11 aufliegenden Exemplare in Falzklappen 16 eines hinter dem Greifer- und Falzmesserzylinder 11 angeordneten Greifer- und Falzklappenzylinders 14 stoßen. Nach der Erzeugung des zweiten Querfalzes erfolgt die Abgabe der Exemplare, beispielsweise an eine Bandleitung 17.A gripper and folding knife cylinder 11 is arranged behind the folding jaw cylinder 8 and has the gripper 12 and folding knife 13. With the help of the grippers, the copies which have already been folded once on the folding jaw cylinder 8 are transferred to the gripper and folding knife cylinder 11. Now, in the manner according to the invention, a transverse perforation is produced on the fold back before the second transverse fold to be subsequently produced. This is done in that the folding knives 13 of the gripper and folding knife cylinders 11, which are designed as perforating knives, are controlled against the perforating groove 10 of the folding jaw cylinder 8, as a result of which the perforation rests on the gripper and folding jaw cylinder Copy is generated. The second transverse fold is then produced, in which the folding knives 13 push the specimens lying on the gripper and folding knife cylinder 11 into folding jaws 16 of a gripper and folding jaw cylinder 14 arranged behind the gripper and folding knife cylinder 11. After the second transverse fold has been produced, the copies are delivered, for example to a ribbon line 17.

Eine weitere Produktionsmöglichkeit besteht darin, daß die mittels der Zylinder 5 und 8 einmal quergefalzten Produkte direkt von den Greifern 15 des Greifer- und Falzklappenzylinders 14 von dem Greifer- und Falzklappenzylinder 11 übernommen werden. Bei dieser Produktionsart sind die Falzmesser 13 und die Falzklappen 16 außer Funktion. In vorteilhafter Weise kann der Punktur- und Falzmesserzylinder 5 auch als Sammelzylinder ausgebildet sein, um vor der Erzeugung des ersten Querfalz auf diesem zugeschnittene Exemplare zu sammeln und gemeinsam zu falzen. Wenn kein zweiter Querfalz erforderlich ist, wird auch zwischen den Zylindern 11 und 8 keine Perforierung erzeugt, d.h. die als Perforiermesser ausgebildeten Falzmesser 13 werden nicht gegen die Perforiernut 10 gesteuert.Another production possibility is that the products which are once folded crosswise by means of the cylinders 5 and 8 are taken over directly by the grippers 15 of the gripper and jaw cylinder 14 from the gripper and jaw cylinder 11. In this type of production, the folding knives 13 and the folding jaws 16 are inoperative. Advantageously, the puncturing and folding knife cylinder 5 can also be designed as a collecting cylinder in order to collect and fold copies of specimens cut onto the first transverse fold before it is produced. If no second transverse fold is required, no perforation is produced between the cylinders 11 and 8, i.e. the folding knives 13 designed as perforating knives are not controlled against the perforating groove 10.
