Abstract

Die Erfindung betrifft ein Verfahren zur Reinigung von Zylindern und Walzen in einer Druckmaschine Aufgabe der Erfindung ist es ein Verfahren zu entwickeln, daß insbesondere in der Betriebsart

Figure 80000001
Reinigen von Walzen" die äußere Reibung an den Walzenoberflächen aufrecht erhält, so daß kein Abfall der übertragbaren Umfangskraft zu verzeichnen ist. Gelöst wird es dadurch, daß bei aktivierter Sprüheinrichtung eine mit einem separaten Antrieb gekoppelte Duktorwalze, bezogen auf einen im Druckbetrieb oder Lackierbetrieb üblichen maximalen Produktionswert zeitlich begrenzt überhöht angetrieben wird und die zugeordnete Auftragwalze mit synchroner Umfangsgeschwindigkeit zur Umfangsgeschwindigkeit der Duktorwalze vom Plattenzylinder her angetrieben wird.
Figure 00000001
The invention relates to a method for cleaning cylinders and rollers in a printing press. The object of the invention is to develop a method that in particular in the operating mode
Figure 80000001
Cleaning rollers "maintains the external friction on the roller surfaces, so that there is no drop in the transmissible circumferential force. It is solved in that, when the spraying device is activated, a ductor roller coupled to a separate drive, based on a maximum that is usual in printing or painting operations Production value is temporarily exaggerated and the assigned application roller is driven from the plate cylinder at a synchronous peripheral speed to the peripheral speed of the duct roller.
