Abstract
A self-lubricating ring assembly (10) for use in forming a finish portion (F) of a hollow formable glass parison (P), the neck ring assembly (10) having an opposed pair of part cylindrical metallic neck ring sections (22a, 22b) that can be opened and closed with respect to one another. The opening and closing of the neck ring sections is guided by a guide ring assembly (24) that is made up of a larger diameter flange member (26) and a smaller diameter hub member (28) that is coaxially and removably joined to the flange member (26). A peripheral portion of the flange member (26) is slidably received in a slot that is defined by opposed slot portions (30, 30b) of the neck ring sections (22a, 22b). The flange member (26) of the guide ring assembly (24) is formed of graphite, to eliminate the need for external lubrication of the neck ring assembly (10), and the hub member (28) is formed of a hardened metal alloy.
