Abstract:
A cleaning apparatus for a backing of a printing machine comprising:at least one rotor having a circumferential outer surface;wherein said at least one rotor is mounted by at least one axle adjacent to a backing path so that at least one central axis of said at least one rotor is oriented perpendicularly to a backing path direction in a plane which is approximately parallel to a plane of said backing path;wherein said at least one rotor is mounted at a mounting distance which is the orthogonal distance between a closest tangent line of said circumferential outer surface and said backing path;a plurality of rotor bristles each having a fixed end and a free end and a bristle length;wherein said fixed end of each of said rotor bristles is attached to said circumferential outer surface of said at least one rotor such that said free end is capable of extending radially from said at least one rotor in response to any centrifugal force caused by a rotation of said rotor;and wherein each of said rotor bristles comprises a limp flexible strip;wherein said mounting distance is about substantially less than said bristle length;and further comprising means to provide a rotational force to said rotor to operate said apparatus so that a segment of each of said bristles lengths strikes and wipes along the backing.
