ABSTRACT:
An air bag actuator is incorporated into the redraw motion assembly of a can body maker apparatus to maintain a cam actuated arm in compression during the reform cycle. Additionally, a housing is provided to enclose an air bag actuator, preventing axial displacement of the air bag and inadvertent damage to it during operations. The air bag actuator also functions as a pivotal link in the redraw system and eliminates the need for a complex pneumatic systems that include surge tanks, air supply tanks, and housing.
