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.).
Claims12
A cutting cylinder for transversely cutting or perforating a material web running in a rotary press, comprising:
- a displacing surface forming a part of the cutting cylinder;
- a cutter bar pressing against said displacing surface, said cutter bar having a contact surface and a first longitudinal side with a first wedge surface and a second longitudinal side with a second wedge surface;
- a first adjusting means for displacing said cutter bar in a circumferential direction, said first adjusting means being connected to said cutter bar in a frictionally engaged manner pressing said cutter bar via said first wedge surface, said first wedge surface being directed toward said displacing surface to form an acute angle with said displacing surface;
- and
- a second adjusting means for displacing said cutter bar in another circumferential direction, said second adjusting means being connected to said cutter bar in a frictionally engaged manner pressing said cutter bar via said second wedge surface, said second wedge surface being directed toward said displacing surface to form an acute angle with said displacing surface.
