Abstract: A method and apparatus for forming a uniformly sized flange on one end of a can body. The apparatus comprises a plurality of vertically spaced assemblies operating relative to a vertical centerline. A bottom lifter plate serves to position a can body vertically with respect to an annular die assembly. The die assembly has radially slidable segments for abutting the can body and for providing a lip about which the body edge is bent to form the flange. Spaced above the die assembly and movable vertically is a punch assembly which serves to both bend the edge about the annular lip on the die assembly and to move the die segments radially inwardly toward the vertical centerline. After the flange is formed, the lifter plate raises the can body above the top edge of the annular lip after which the die segments are opened and the can body lowered to remove it from the flanging apparatus.
