ABSTRACT:
Gear wheel play between cooperating gears of two cylinders whose axial spacing can be varied, in a rotary printing press can be eliminated by use of a free wheeling gear supported on the journal of the first of the two cylinders and engaging the gear wheel on the second cylinder. A circumferential shifting of the free wheeling gear will eliminate gear wheel play. A phase adjusting gear assembly is used to accomplish the circumferential phase shifting of this gear.
