ABSTRACT:
A method for cleaning a rotating cylinder in a printing machine, such as the rubber-blanket or impression cylinder, is disclosed. In accordance with the present invention, the printing machine includes a washing roller for engaging and cleaning the rotating cylinder. The washing roller is rotated in the same direction as the direction of rotation of the rotating cylinder during at least part of the period in which the washing surface of the washing roller engages the rotating cylinder. Preferably, the washing roller is first rotated in a direction opposite to the direction of rotation of the rotating cylinder, then reversed to rotate in the same direction as the direction of rotation of the rotating cylinder.
