ABSTRACT:
A self-oscillating roller assembly (11, 13) and method of oscillating a roller in an offset printing press having an oscillating drive assembly (11) for oscillating a rotationally mounted roller (10, 12) with a source of pneumatic pressure (62) by alternatively applying pressure to pressure chambers (42A, 42B) on opposite sides of the roller (10, 12) to impart a longitudinal force on the oscillating roller (10, 12) from the source of pressure (62) in two opposite directions and a controller (47) for controlling the application of pressure (58, 62) to alternately move the rotationally mounted roller in two opposite directions.
