ABSTRACT:
Beading of containers such as two and three piece can bodies by rolling the can body between tools, typically a roll/roll or a roll/rail of a rotary turret system. During beading, a load is applied along the central axis of the can body, whereby axial and panel performance of the beaded can is improved. This load is applied for example by the use of miniature air bags which are fixed to the turret.
