Abstract

A device to clean an outer cylindrical surface of a cylinder in a rotary printing press includes a cleaning cloth. The cleaning cloth can be pressed against the cylinder surface and is wound off a supply roller. To increase the effectiveness of the cleaning action, the cleaning cloth is wetted with a cleaning fluid upstream of the cylinder. The cleaning fluid can be fed via a feed tube to an absorbent wetting pad to uniformly distribute the cleaning fluid over the width of the cleaning cloth.
