ABSTRACT:
A device for perforating, die-cutting, cutting or creasing in printing machines comprises a supporting foil which at two of its opposite sides is provided with strips for mounting onto a rubber blanket cylinder of a printing unit, whereby a component for perforating, die-cutting, cutting or creasing is affixed to the supporting foil. An impression cylinder covered with a protection foil co-operates with the rubber blanket cylinder. The use of a relatively hard supporting foil instead of a rubber blanket allows for much cleaner and quicker perforation and punching, and the affixing of the perforating, die-cutting, cutting or creasing component to the supporting foil on the rubber blanket cylinder allows a much easier and more precise positioning of that component. As a result, the device can also be used in endless printing machines. Moreover, the use of an independent inner underlying blanket allows an exact calibration of the total thickness of the supporting foil comprising the working tools. The device can also be used for envelope printing or spot varnishing.
