ABSTRACT:
An H-28 machine has a plurality of identical sections each processing a gob of molten glass into a parison and then into a piece of ware each complete revolution of the section. Each section includes a blank mold displaceable between a parison forming position and a retracted position by blank mold down air.
Each section also includes a plunger which is displaceable from an elevated position down to the parison forming position and a neck ring assembly which includes an air motor. Finally the section also includes a blow mold displaceable from a remote position to a closed position. The air motor is operated from the time that the blank mold begins its displacement from the parison forming position to the retracted position by a valve which connects blank mold down air to the air motor.
