ABSTRACT:
Foreign particles are removed from the plate cylinder of an offset press by interconnecting two ink form rollers friction driven by the plate roller and/or a vibrating roller to rotate in unison at different surface velocities. The connection between the form rollers maintains a fixed ratio between the surface velocities of the rollers which is other than 1:1 and causes the surface of at least one of the form rollers to wipe the surface of the plate.
