ABSTRACT:
A drive device for reciprocating and rotating a roller such as a dipping roller in a dampening unit in a printing press is disclosed. The drive device includes a first driven unit and a second driven unit. The first driven unit reciprocates the driven roller along its axis whereas the second driven unit rotates the driven roller about that same axis. A coupling is provided in either the first or the second driven unit, or both, to permit the selective deactivation of one or more of the driven units to permit the drive to either rotate the roller without reciprocation, to reciprocate the roller without rotation, or to simultaneously rotate and reciprocate the roller.
