Patent ID: 7024900

Claim:
A method of beading a container comprising the steps of: mounting a can body ( 1 ) on a first tool ( 11 ) such that the can body ( 1 ) is freely rotatable; moving the can body ( 1 ) and the first tool ( 11 ) into contact with a second tool ( 13 ) such that the can body ( 1 ) is clamped between the first and second tools ( 11 , 13 ) and at least one of the tools includes a beading profile; applying an axial load along a central axis of the can body; forming circumferential beads in a side wall of the can body by rolling the can body between the first and second tools ( 11 , 13 ); the can body having a diameter of from substantially 60 to 250 mm, a can wall thickness of from substantially 40T (0.102 mm) to 60T (0.152 mm) and the applied axial load ranging between substantially 300 N to 600 N; and applying the axial load as a positive axial, net compressive load on the can body and maintaining the positive axial, net compressive load on the can body during bead formation.
