    摘要: 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.

    摘要: A washing device for a cylinder in a printing press includes a washing cloth for removing contaminants and ink, etc. from the surface of the cylinder and an ultrasonic source directing sound energy onto the surface of the cylinder to assist a washing operation. A focusing device disposed in front of the ultrasonic source concentrates the sound energy on a substantially linear focus region on the surface of the cylinder, extending parallel to the axis of the cylinder.
