Abstract

A device for clamping the trailing edge of a printing plate in a plate cylinder of a rotary printing machine includes a torsion bar disposed in a cylinder gap formed in the plate cylinder and extending in axial direction thereof, clamping elements affixed to the torsion bar and cooperating with holding elements for clamping the printing plate, and actuators provided on both sides of the plate cylinder for stretching the printing plate in axial direction. The torsion bar is of bipartite construction, and the actuators, respectively, are mounted so as to be displaceable axially independently of one another.
