ABSTRACT:
To clean dusts from a printing cylinder of a blanket, an impression drum or the like can be simply discharged with no adhesion in a casing of a cleaning machine. A cleaning device incorporates a rotary brush in the casing which is disposed opposite to the printing cylinder. An opening is formed in a cylinder confronting portion of the casing, and the cylinder surface can be cleaned by the brush, with some portion of the brush fronting. Provided in the casing is a scraper for eliminating the adhered substances while contacting the brush. A dust discharge port is formed in the wall surface of the casing, and an air blowout means for forming an air layer is provided in the bottom portion of the casing. The dusts taken in by the brush are carried through the air layer to the discharge port while floating the dusts and can be discharged from the discharge port.
