ABSTRACT:
Methods of necking-in and flanging tubular can bodies having body walls of constant thickness. A pilot die initially inserted into the tubular can body reverses its direction during the necking-in operation with respect to the motion of a ring die member that contacts the exterior surface of the tubular can body member. This concurrent reverse movement of the two forming dies eliminates wrinkles in the necked-in region and produces a container body with increased columnar strength. Repetitive use of the method produces containers with two or three necked-in portions. A method is also disclosed for relubricating the necked-in area of the tubular can body between the successive necking stations.
