ABSTRACT:
A printing cylinder cleaning apparatus includes a brush roller having brush fibers planted on its outer surface and opposed to a printing cylinder for movements to and away from a position where the brush fibers contact a surface of the printing cylinder, and includes a rotational driver for rotating the brush roll. The brush roller is contained in a casing which also contains a scraper for biting contact with the brush roll and a dust collector for receiving dust removed by the scraper. The scraper is rotationally supported to casing to follow and rotate with rotation of the brush roll or to be rotationally driven by a motor. The scraper may be an elongated polygonal bar twisted in an intermediate portion, or having a splined or knurled outer circumferential configuration.
