Abstract
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.
