Abstract

A cutting cylinder for transversely cutting or perforating a material web running in a rotary press, preferably a printed web in a rotary printing press, has at least one displaceable cutter bar. The cutter bar, pressing a displacing surface provided at the cutting cylinder with a contact surface, is displaceable in the circumferential direction of the cutting cylinder by an adjusting device connected to the cutter bar in a frictionally engaged manner pressing the cutter bar via at least one wedge surface. The wedge surface points toward the displacing surface at an acute angle (.alpha.).
