Abstract
A mechanically programmed indexing turret assembly configured to independently position each of a plurality of mandrels about a central axis of the turret for periodic interaction with a plurality of work stations. A central standard rotates at a substantially constant angular velocity. Each mandrel is mounted about the axis of the standard for rotation about a common axis therewith. The standard selectively transmits torque to the various mandrels in conjunction with cam and linkage elements. The respective periods of angular acceleration, deceleration, and absolute dwell of the respective mandrels are controlled in accordance with a predetermined cam contour associated with the cam track.
