Description
Die Erfindung betrifft eine Vorrichtung zum Querperforieren nach dem Oberbegriff von einem der Ansprüche 1 bis 3.The invention relates to a device for transverse perforation according to the preamble of one of claims 1 to 3.
Um das Querfalzen von Bogen und deren Weiterverarbeitung nach dem Falzvorgang zu erleichtern, ist es bekannt, die Bogen deckungsgleich zum nachfolgenden Querfalzen mit einer Querperforation zu versehen. Damit ist zwangsläufig eine exakte Einstellung der Querperforation zum Querfalz unter Einbeziehung erforderlicher Korrekturen von Falzdifferenzen oder der Verstellung des Vorfalzes bzw. Überfalzes verbunden.In order to facilitate the transverse folding of sheets and their further processing after the folding process, it is known to provide the sheets congruent with the subsequent transverse folding with a transverse perforation. This inevitably involves an exact setting of the transverse perforation to the transverse fold, including the necessary corrections of fold differences or the adjustment of the pre-fold or over-fold.
Bei mit zwei Querfalzvorrichtungen ausgestatteten Falzapparaten erfolgt die Korrektur der dem ersten Querfalz zugeordneten Querperforation durch eine entsprechende Verdrehung eines mit Perforiermessern und -leisten ausgerüsteten Perforierzylinderpaares gegenüber dem den ersten Querfalz ausführenden, aus einem Falzmesser- und einem Falzklappenzylinder bestehenden Falzzylinderpaar. Die Verstellung kann während des Maschinenlaufes, beispielsweise mit Hilfe eines entgegengesetzt schrägverzahnten, in den Zahnradantrieb zwischen beiden Vorrichtungen eingefügten Zweifachstirnzahnradschiebeblockes, erfolgen.In the case of folding apparatuses equipped with two transverse folding devices, the correction of the transverse perforation associated with the first transverse fold is carried out by correspondingly rotating a pair of perforating cylinders equipped with perforating knives and strips relative to the pair of folding cylinders comprising a folding knife and a folding jaw cylinder. The adjustment can be made while the machine is running, for example with the aid of an oppositely helical toothed double sliding gear block inserted into the gear drive between the two devices.
Die Einstellung der dem zweiten, von einer weiteren Falzzylindergruppe ausgeführten Querfalz zugeordneten Querperforationen wird hingegen im Maschinenstillstand durch eine Einzelverstellung der betreffenden Perforiermesser und Perforierleisten mit beispielsweise an deren Halterungen angreifenden, anderseitig mit dem Perforierzylinderkörper verbundenen Justierschrauben vorgenommen.The setting of the transverse perforations assigned to the second transverse fold performed by a further folding cylinder group, on the other hand, is carried out when the machine is at a standstill by individually adjusting the relevant perforating knives and perforating strips with, for example, adjusting screws which engage their holders and are otherwise connected to the perforating cylinder body.
Dadurch wird die Effektivleistung der Rotationsdruckmaschine verringert und die Entstehung von Makulatur begünstigt. Außerdem sind die im Falzapparat an den Perforierzylindern vorzunehmenden Einstellungen hinsichtlich des Bedienkomfortes negativ zu bewerten.This reduces the effective output of the rotary printing press and promotes the creation of waste. In addition, the settings to be made in the folder on the perforating cylinders with regard to ease of use are to be assessed negatively.
Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zum Querperforieren gemäß dem Oberbegriff von einem der Ansprüche 1 bis 3 zu schaffen, die eine den Anforderungen des ersten und zweiten Querfalzes gerecht werdende Verstellung der den Querfalzen jeweils zugeordneten Querperforationen während des Maschinenlaufes ermöglicht.The invention has for its object to provide a device for transverse perforation according to the preamble of one of claims 1 to 3, which enables the cross-perforations associated with the cross-folds to be adjusted while the machine is running, which meets the requirements of the first and second transverse folds.
Diese Aufgabe wird durch die kennzeichnenden Merkmale für Anspruch 1 bis 3 gelöst, wobei bei der Lösung gemäß Anspruch 1 alle Perforiermesser sowohl zum ersten als auch zweiten Querfalz, bei der Lösung gemäß Anspruch 2 zusätzlich die Perforationsleiste für den ersten Querfalz und bei der Lösung gemäß Anspruch 3 zusätzlich alle Perforationsleisten für den ersten und zweiten Querfalz jeweils lagegerecht eingestellt werden.This task is characterized by the characteristics of Solved claims 1 to 3, wherein in the solution according to claim 1 all perforating knives both for the first and second transverse fold, in the solution according to claim 2 additionally the perforation bar for the first transverse fold and in the solution according to claim 3 additionally all perforation bars for the first and second cross fold can be adjusted according to position.
