ABSTRACT:
Glassware forming apparatus includes a parison mold, a blow mold, a pair of neck rings for supporting glassware blanks, first and second invert arms for supporting the neck rings and first and second arbors for supporting the first and second invert arms, respectively. The invert arms support their respective neck rings for movement in a common vertical plane. The axes of the arbors extend generally parallel to one another and generally perpendicular to the common plane. The molds have parallel vertical axes lying in said common vertical plane. Apparatus is provided for shifting the arbors such that their axes move toward and away from one another during an operating cycle. Apparatus is provided for pivoting the arbors about their axes to move the neck rings in invert and revert arcs between the parison mold and the blow mold. The method comprises the steps of moving the neck rings into registry with the parison molds to receive a gob of molten glass to form a blank, inverting the neck rings to support the blanks at a reheat station and then shifting the neck rings to present the blanks for engagement by a blow mold.
