Abstract
A printing unit cylinder and a sleeve for a printing unit cylinder is disclosed. The printing unit cylinder has an axial end section on the operator's side and a lateral surface having a plurality of openings through which compressed air can be passed so that a sleeve thereby widened can be pulled onto the lateral surface and pulled off of it over the axial end section. A noise reduction structure is provided on the axial end section for reducing the noises generated by compressed air emerging between the sleeve and the lateral surface. The noise reduction structure is equipped to support an inside circumferential surface of the sleeve on the axial end section over at least a portion of its circumference, so that vibrational excitation of the sleeve based on the escaping compressed air is prevented.
