ABSTRACT:
An apparatus for automatically washing printing units of printing machines with finely perforated rollers, which includes: a hollow body that constitutes the washing water chamber and is anchored laterally and parallel to the color feed tube and has, at its base, a series of nozzles, which are directed towards the inside of the wedge-shaped suction chamber, and a series of similar nozzles which are directed towards the rear part of the suction chamber. A series of nozzles is associated with the color feed tube to direct the color towards the secondary rotating roller and to feed the washing water into the finely perforated roller when printing ends. The apparatus is also provided with wear-preventing pads between the rotating secondary roller and the suction chamber, with pads for axially retaining the secondary roller, and with a device for washing under pressure the opposite ends of the color feed tube, the tubular ends of the washing chamber, and the rings of the finely perforated roller.
