ABSTRACT:
Control device for the offset cylinder of an offset printing machine, said control device selectively governing the movement of the offset cylinder into printing engagement with the plate and impression cylinders of the printing machine and the movement of the offset cylinder away from said plate and impression cylinders to relieve them of printing pressure. The control device mounts the offset cylinder sufficiently stiffly in the frame of the printing machine so as to avoid faults in the printing as, for example, the formation of strips on the printed paper sheets. The offset cylinder is rotatably mounted on an eccentric shaft which is mounted in first adjustable bearings which are arranged in eccentric bushings. On said eccentric bushings there are mounted second adjustable bearings which are arranged in bearing flanges which are adjustably fastened in the side walls of the printing machine.
