ABSTRACT:
A drive system between a master cylinder, a form roller and a distributor roller in a moisture system of a printing, duplicating or like machine. The surface of the master cylinder has a longitudinal gap within which master clamping hardware are disposed. The drive system includes a first gear train, including a lost motion mechanism, between the master cylinder and the form roller for rotating the form roller only during an interval of a revolution of the master cylinder when the surface of the form roller is juxtaposed in the gap of the master cylinder. A second gear train independent of the first gear train is disposed between the form roller and the distributor roller for rotating the distributor roller continuously at the same surface speed as the form roller.
