Abstract
An assembly for preventing a flanged finish on the neck portion of a glass container by permitting continuous engagement between the neck ring and the guide ring even though the guide ring is subject to wear and by forcefully maintaining this continuous engagement with a spring urged centering sleeve which extends through a bore in the neck ring to engage the bottom of the guide ring. The neck ring includes a stepped interior annular groove into which a guide ring having an outer stepped annular portion is received. While the total height of the guide ring corresponds to the total height of the groove of the neck ring, the upper surface (70) of the bottom step (72) of the guide ring establishes a selected clearance (Z) with the upper surface (74) of the bottom portion (66) of the neck ring groove so that the continuous engagement can be maintained as the top surface of the guide ring wears.
