Abstract
A double action press for forming a beverage can lid has a longitudinal axis, an inner tooling, and an outer tooling. The inner tooling is positioned about the longitudinal axis and has a downwardly extending stem. The stem has an upper segment having a free end and a separate lower segment having a proximal end. The proximal end is in communication with, but is not joined to, the lower free end of the upper segment. An opposing distal end is joined to a punch core. The outer tooling is positioned about the longitudinal axis and has a passageway through which a portion of the stem passes, a chamber in which the proximal end of the lower segment of the stem resides and traverses upwardly and downwardly therein, a biasing means within the chamber for biasing the lower segment of the stem in an upward position, and a circumferential tooling assembly.
