Abstract

An auxiliary drive for the ductor roller of a sheet-fed offset press continues to advance the ductor roller in small angular steps during press stoppages. The damping unit drive which continues to run during press stoppages drives the ductor roller stepwise by way of an eccentric drive linkage and a ratchet wheel disposed on the ductor roller journal. When the press is running, a rocker lever in the drive linkage can be pivoted away from the throw zone of the eccentric for example, by a piston actuated by oil pressure of the press's oil supply system. In alternative embodiments, the lever arm can be pivoted away by a compressed air cylinder or a suction cylinder which become operative when the press is running.
