Abstract
An improved can body maker apparatus has a redraw system of reduced mass. An air actuator is incorporated into the redraw motion assembly to maintain a cam actuated arm in contact with a cam surface during the reform cycle. A improved mechanical linkage eliminates the conventional redraw carriage. The redraw sleeve is supported within a fluid bearing mounted in a stationary housing.
