Abstract

A printing press includes an assembly and a cam mechanism for moving at least one part of the assembly. A cam of the cam mechanism has a curvature course with points, in particular bends or jumps, which are not constantly differentiable within a movement region of the cam. The cam mechanism can include an actuator for the temporal displacement of jolts which are induced by the points that are not constantly differentiable to the at least one part of the assembly. An adaptation of the movement which is produced to the operating state of the printing press is possible, with the result that a considerable reduction can be achieved in vibrations for all printing speeds.
