Abstract
A continuous motion decorator of the type in which cans are supported on freely rotatable mandrels during decorating is provided with a plurality of equally spaced mandrel actuator subassemblies mounted along the periphery of a rotating carrier. Each subassembly is mounted for radial movement toward and away from the carrier's rotational axis with the radial position of the subassembly being controlled by a stationary closed loop cam track on which a follower roller of the subassembly is disposed. The subassembly also includes a rotary operator having a rotor that supports the mandrel and is on a pivot axis that is parallel to the axis of the carrier as well as being parallel to and laterally offset from the rotational axis of the mandrel. Sensors detect unloaded and misloaded mandrels, and upon doing so cause the rotary operator that is unloaded or misloaded to be actuated to withdraw the rotor from its normal decorating path so that it will not engage the printing blanket of a decorating unit.
