Abstract
A system for the beading and flanging of opposed ends of a cylindrical can body wherein the opposed beading and flanging chucks are sequentially withdrawn. Stop means is mounted on the can carrying wheel adjacent the flanging chuck and cooperates with the flanging chuck for a retention of the flanged end of the can therein during the initial removal of the beading chuck which inherently effects a greater frictional engagement with the beaded end of the can. The stop allows a free subsequent withdrawal of the flanging chuck. The invention herein is generally concerned with the forming of can bodies for peel-top containers, and more particularly relates to a system for substantially simultaneously beading one end of a cylindrical can body and flanging the second end thereof. Apparatus for the simultaneous or substantially simultaneous flanging or beading of opposed ends of cylindrical cans are evidenced by the following U.S. Pat Nos: PA1 2,424,581 Peters PA1 2,741,292 Butters PA1 2,956,610 Diezel PA1 3,062,263 Austing et al.
