  • Patent number: 4170176
    Abstract: A device for controlling the movement of hollow workpieces in, for example, a printing mechanism environment. Cam surfaces are locked to the interior of the hollow work performing member. A spindle is provided having secured thereto cam rollers operatively connected to the cam surfaces. The cam surfaces are identical in shape and are oriented so that a movement of the cam rollers relative thereto will effect an axial shifting of the hollow work member relative to the spindle. The spindle is driven for rotation by a first drive mechanism. The hollow work member is driven for rotation by a second drive mechanism which can be, in the printing machine environment, a frictional force applied by other driven rollers in the system. When the rotational speed of the spindle is in excess of the rotational speed of the hollow work member, the cam rollers wil move relative to the cam surfaces and effect the aforesaid axial shifting.
