APPARATUS AND METHOD FOR INVESTING A BUMPER EYELASH ON AN INVOLVABLE CLOSURE.

摘要

Apparatus for inverting a stop flange (64) in an inviolable closure (12), from an axially oriented outward position, as molded, to an inwardly oriented use position, which includes: a support base (20) to support the closure so that the abutment flange, as molded, is separated from said support base and oriented away from the latter, a pedestal (28) movably carried by said support base in a separate position of said support base, a locator ring (40) carried by said pedestal and which can be moved with said pedestal to engage the stop flange on a closure carried by said support base and to bend the stop flange radially towards the interior, and an inverter ring (64) intended to move through said locator ring to engage and invert the radially curved stop flange inwardly by said locator ring to the position for use oriented axially inwards.
