Abstract
A retainer for firmly holding a printing plate on a plate-carrying cylinder by a hook that engages in an elongated gap formed in the cylinder and is fixedly connected to a tension rod guidable rotatably by drive mechanisms so that it is alignable relatively to two limiting directions in accordance with two limit positions. The drive mechanisms include a piston rod that is supported in a longitudinal bore formed in the cylinder, the piston rod carrying a plurality of pistons distributed over the entire length thereof and including a longitudinal conduit selectively suited for supplying pressure medium for positioning the pistons selectively in two extreme positions.
