ABSTRACT:
A washing apparatus for a printing roll, particularly a flexographic printing roll having raised printing areas. The washing apparatus includes a troughlike housing provided with an open mouth positioned adjacent the peripheral surface of the printing roll. The housing, surrounding the open mouth, has sealing strips which engage the print roll surface. First and second nozzles are mounted in the housing for respectively discharging streams of cleaning liquid and rinsing liquid against the periphery of the roll as it moves past the mouth of the housing. A brush is positioned within the housing for contacting the print areas on the roll generally between the regions contacted by the nozzle streams. The liquid and debris collect within the housing, and are sucked therefrom for exterior discharge.
