Abstract
Device for cleaning a rotating outer cylindrical surface, such as the surface of a printing-form cylinder, for example, in a printing press, with a cleaning-cloth web having edges oriented perpendicularly to the direction of generatrices of the outer cylindrical surface, including a cleaning-cloth web supply coil and a winding coil, the cleaning-cloth web being transportable from the supply coil to the winding coil, and a pressure element for pressing a section of the cleaning-cloth web against the outer cylindrical surface to be cleaned, further includes a holder extending in axial direction of the outer cylindrical surface and embracing the pressure element, the pressure element being disposed parallel to the rotational axis of the outer cylindrical surface, and a profile extending in the axial direction and covering the pressure element, the profile being provided with press-on material acting on the cleaning-cloth web from a side thereof opposite to the outer cylindrical surface.
