ABSTRACT:
A cleaning apparatus for a rotary printing press includes a cleaning blade, a cleaning cloth, and a cleaning unit and air cylinders, or an air cylinder, a guide shift mechanism, and a cleaning cloth travel mechanism. The cleaning blade has a distal end portion which abuts against the circumferential surface of an oscillating roller during a cleaning operation to scrape a waste ink, and a rear surface continuous to the distal end portion to guide the scraped waste ink downward. The cleaning cloth travels during the cleaning operation done by the cleaning blade to collect the waste ink scraped by the cleaning blade. The cleaning unit and air cylinders, or the air cylinder, the guide shift mechanism, and the cleaning cloth travel mechanism bring the cleaning cloth into contact with the rear surface of the cleaning blade, when the distal end portion of the cleaning blade is in contact with the circumferential surface of the oscillating roller, to collect the waste ink on the cleaning blade.
