ABSTRACT:
In a printing cylinder with an adjustable side register and having internally conical ends by which the cylinder is clamped in position between external cones, the external cones are on the confronting ends of journals. One of the journals is axially immovable in a first sleeve which is axially displaceable but non-rotatable. The first sleeve is screw-connected to an axially immovable second sleeve provided with a rotary drive for adjusting the cylinder axially. The journals can be stressed towards each other by the piston rods of hydraulic piston-cylinder units of which the cylinders can be interconnected and have oppositely varying volumes when the side register is being adjusted.
