Abstract

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.
