ABSTRACT:
An I.S. machine has a plurality of individual sections arranged in side by side relation. Each section has a blank station for forming a parison from a gob of molten glass, and a blow station for forming a parison into a bottle. An invert and neck ring holder mechanism is located between these stations for transferring a parison between from one station to the other. Each station has a mold opening and closing mechanism which has a pair of opposed mold support mechanisms supported for linear displacement between a retracted position and an advanced position. Each mold support mechanism is supported by a first shaft on one side of the center of the mold opening and closing mechanism, proximate the invert and neck ring holder mechanism, extending perpendicularly to the engagement plane, and by a second shaft on the other side of the center of the mold opening and closing mechanism, remote from the invert and neck ring holder mechanism, extending perpendicularly to the engagement plane. The second shaft is second interconnected with the mold support mechanism enabling relative motion between the mold support mechanism and the second shaft in the parison transfer direction so that expansion of the mold support mechanism will take place in the transfer direction away from the invert and neck ring holder mechanism.
