ABSTRACT:
A can body suitable for inward necking of the flange region is disclosed in which the flange region thereof includes a plurality of corrugations to increase the effective thickness and thus the stiffness of the metal in this flange region. A method and apparatus for producing these can bodies are also disclosed. The apparatus employed includes a pair of generally circular matched die members which are positioned on either side of the flange region of the can body to be corrugated and a means for rotating the can body, and thus the die members, when contacting the flange region of the can body.
