ABSTRACT:
A system and apparatus for roll forming to neck-in D&I can ends and replace double necks and triple necks is disclosed. An externally disposed free roll having independently rotatable sections is moved inward and axially against the outside wall of the open end of a rotating trimmed can to form a conical neck at the open end of the cap, the two sections of the roller having different speeds depending upon neck diameters respectively engaged thereby. A spring loaded interior support roller moves under the forming force of the free roll. This is a single operation where the can rotates and the free roll rotates such that a smooth conical necked end and flange are produced.
