ABSTRACT:
A method and apparatus for necking and flanging container bodies are disclosed. One or more free-wheeling dies are rotated within a stationary outer die and are journeled for radial movement within the outer die. The open edge portion of a metallic can body is positioned between the dies, with the action of the dies forming a neck on the can body. Subsequently, the necked end of the can body may be contacted with a flanging surface of the free-wheeling die or dies, forming a flange on the outer edge of the container body.
