ABSTRACT:
An ink cleaning apparatus for a rotary printing press includes a blade shaft, a rewind roller, a take-up roller, a hygroscopic band member, and a doctor blade. The blade shaft is pivotally supported to be parallel to an ink roller near the ink roller. The rewind roller and the take-up roller are respectively supported in parallel to the blade shaft. The hygroscopic band member is rewound from the rewind roller and taken up by the take-up roller after being brought into contact with the blade shaft. The doctor blade is fixed on the blade shaft. The distal end portion of the doctor blade is brought into contact with an outer surface of the ink roller upon pivotal movement of the blade shaft in one direction. The flat surface of the doctor blade which is attached with a waste liquid is brought into tight contact with the band member upon pivotal movement of the blade shaft on the other direction.
