Abstract

A roller for a printing unit of a printing press, has a roller outer body, which is mounted on a roller inner body, so as to be movable axially in a reciprocating manner. For the axial movement of the roller outer body, in at least a first direction, a pneumatic drive is provided. The pneumatic drive has at least one first chamber, which is mounted in the interior of the roller in the manner of a cylinder/piston system between one or more structural elements, that are fixed to the roller outer body, and one or more structural elements that are fixed to the roller inner body. The chamber can be pressurized with compressed air. The parts of the structural elements adjoining the chamber, and that are movable axially relative to one another, form a non-contact seal between themselves on their mutually facing sides.
