Abstract
A blanket cleaning apparatus is provided for cleaning ink from a blanket cylinder of a rotary offset duplicating machine. The apparatus comprises a cleaning roller for contact with the blanket cylinder, a wiper roller and a metering roller in contact with each other and with the cleaning roller, and a wringer roller in interfering relation with the wiper roller at the zone of contact to effect deformation of the peripheral surface of the wiper roller. A cleaning fluid is supplied to the wringer roller which transfers the fluid to the wiper roller and meters the amount of fluid carried by the wiper roller to the cleaning roller for cleaning the blanket cylinder. The cleaning and the wiper rollers are driven at surface speeds differing from the surface speeds of the blanket cylinder and the cleaning roller respectively, such that the cleaning roller cleans the blanket cylinder with a scrubbing action in a minimum number of revolutions of the blanket cylinder, and the wringer roller maintains the wiper roller clean of ink and contaminated cleaning fluid for long periods without requiring cleaning maintenance of the apparatus.
