ABSTRACT:
A can body embossing apparatus has a first mandrel with a first tooling member adapted to receive thereon a can body and a second mandrel with a second tooling member reciprocally movable from a first position distal the first tooling member to a second position proximate the first tooling member. In the second position, the can body side wall is engaged between the first tooling member and the second tooling member. The first tooling member defines one or more recessed portions therein and the second tooling member defines one or more protuberances extending therefrom and adapted to correspond with the recessed portions. The first mandrel and second mandrel are in mechanical communication throughout the reciprocal movement of the second mandrel such that the first and second tooling members rotate continuously with respect to each other and maintain a substantially constant relative position with respect to each other. The continuous side wall of the can body is conveyed between the first and second tooling members to effect the embossing of the side wall resulting in the formation of decorative embossed features in the side wall.
