A device for automatically changing printing plates is provided in a printing machine having a plate cylinder to which a printing plate is to be fed and on which the printing plate is to be fixed detachably. The device includes a transport system for conveying the printing plate while permitting axial compensating movements thereof. The transport system has at least one driven transport roller and an air cushion for holding the conveyed printing plate in contact with the transport roller. The plate-holding air cushion is formed between a counterpressure element, on one side, and the printing plate, on the other side.

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.
