ABSTRACT:
An apparatus for erasing a plate cylinder of an offset printing press includes a first guide unit which is mounted to the offset printing press apart from the plate cylinder and which extends in an axial direction of the plate cylinder. A mounting unit includes at least two spaced mounting members mounted on the first guide unit, an elongated base plate spanning and fixed to the mounting members, and a sliding-plate assembly mounted longitudinally and movably on a top surface of the base plate for holding an erasing member which is used for erasing impurities on the plate cylinder. A pair of second guide units are mounted respectively and securely to two opposite transverse ends of the elongated base plate for guiding movement of the sliding-plate assembly on the elongated base plate in a direction toward the plate cylinder. A pair of driving units are mounted respectively on the second guide units for moving the sliding-plate assembly relative to the elongated base plate so as to push the erasing member against the plate cylinder.
