Method of and apparatus for shaping neck and providing terminal curl on can end.

摘要

This relates to the forming of a flared neck terminating in an outwardly turned curl on a metal can end. The metal can end (10) is formed with a terminal tubular portion (20) which is cylindrical. Suitable punch and die tooling (30) is provided for backing up the partially formed can end surrounding the tubular portion (20) and forcing the same into cooperating relation with a curl insert (52), simultaneously to flare the tubular portion (20) and to form on the end of the tubular portion an out-turned curl (28). The relationship of the tooling is such that the extent of the flared neck thus formed is accurately controlled.
