ABSTRACT:
Neck ring apparatus is disclosed for retaining and conveying glass along a predetermined path as the glass is transformed from an initially formed parison to a final blown glass article having a desired finish. A pair of sprockets, forming a part of the neck ring mechanism, selectively engage roller tracks as the mechanism proceeds along its predetermined path to (1) open segments of the neck ring so as to permit the delivery of a charge of molten glass to a mold position therebelow, (2) to close the neck ring segments so as to form a finish on an initially formed parison and retain such parison by said finish, (3) rotate the neck ring and accordingly said parison for uniformly cooling the parison and for removing blow mold seams during the blowing of the final article, and (4) to open the neck ring segments to remove the finished article therefrom.
