ABSTRACT:
Glassware forming apparatus includes a turret mounted for rotation about, and projection along, a vertical axis. First, second, third and fourth arms are rigidly mounted on said turret to extend horizontally and radially outwardly. The first arm supports a first neck ring. The second arm supports a second neck ring. The third arm supports a first blow head. The fourth arm supports a second blow head. The apparatus further includes a parison mold and first and second blow molds. Each of the blow molds is divided into two mold portions joined along a vertical hinge. The axes of the blow mold hinges extend generally parallel to the turret axis. Apparatus is provided for opening and closing the molds, for pivoting the turret about its axis and for projecting the turret along its axis to position the first and second neck rings alternately in engagement with the parison mold, to convey blanks supported from the first and second neck rings to the first and second blow molds, respectively, and to position the first and second blow heads in engagement with blanks conveyed to the first and second blow molds, respectively. The method of the present invention involves moving the arms to form blanks on the neck rings in the parison mold, to deposit the blanks in the blow molds, to engage the blanks in the blow molds with the blow heads and to remove the finished glassware to a removal station.
