Abstract

A method and apparatus for pressing glass articles. A single mold may be utilized for each article being pressed. The plunger has a ring-like member movably attached thereto. After pressing, when the plunger is retracted from the plunger, the plunger retains the glass article thereon. The ring-like member is then lowered relative to the plunger, thereby removing the pressed article therefrom.
