Abstract
A washing apparatus for cleaning the surface of cylinders in a printing machine includes a fresh-cloth roller, a washing roller and a dirty-cloth roller. A washing cloth is transported from the fresh-cloth roller via the washing roller to the dirty-cloth roller. A spring-band freewheel in the form of a helical coil spring is wound non-positively on the shaft of the fresh-cloth roller. The spring-band freewheel free-wheels during the rotation of the shaft in the direction of tension applied to the washing cloth and blocks the shaft from rotating in the opposite direction. The necessary cloth tension is guaranteed, at the same time, by means of the resilient effect of the spring-band freewheel.
