Abstract
In an intaglio printing press, apparatus for applying and withdrawing a pressure cylinder to the plate cylinder during replacement of the latter comprises displaceable journals for the pressure cylinder operatively connected to a piston-cylinder unit. To control the withdrawing motion of the pressure cylinder, a pressure medium is fed beneath the piston by way of a pressure regulating valve which is open during printing and which is moved to a closed position by a cam carried along by the piston rod.
