ABSTRACT:
A device for stretching the rear edge of a printing plate in the plate cylinder of a rotary printing press. An extension shaft is provided in a channel which extends in the longitudinal direction of the plate cylinder, whereby fastened to the extension shaft are stretching elements which interact with retaining elements and make possible a stretching of the printing plate. Adjustment means are provided on both sides of the extension shaft, which adjustment means are supported on the cylinder cheeks and make possible an extension of the printing plate in the axial direction. The device makes possible, in addition to the extension of the rear edge of the printing plate, a lateral offset by a small amount.
