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.
Glassware forming apparatus comprising at least first and second neck rings for supporting glassware, at least first and second blow heads, first and second arms for supporting the first and second neck rings, respectively, third and fourth arms for supporting the first and second blow heads, respectively, a turret for rigidly supporting the first, second, third and fourth arms for pivotal movement about a common vertical axis, a parison mold and first and second blow molds, means for opening and closing the molds, means providing a rest position, and means for pivoting the turret about its axis first in one direction and then in the opposite direction to position the first and second neck rings alternately in engagement with the parison mold, to convey all blanks supported from the first neck ring to the first blow mold, to convey all blanks supported from the second neck ring to the second blow mold, to move the first blow head between a position in engagement with blanks conveyed to the first blow mold to blow them into glassware, and the rest position, and to move the second blow head between a position in engagement with blanks conveyed to the second blow mold to blow them into glassware, and the rest position.
Glassware forming apparatus comprising first and second neck rings, first and second blow heads, a parison mold, first and second blow molds, means defining a finished glassware location, means for opening and closing the parison mold and the blow molds, a turret, means for supporting the first and second neck rings and first and second blow heads from the turret, and means for movably supporting the turret, the parison mold, the first and second blow molds and the finished glassware location being disposed at approximately 90.degree. intervals about the periphery of a circle with the parison mold substantially diametrically opposite the finished glassware location and the blow molds being substantially diametrically opposite one another, the turret being substantially vertically above the center of the circle, the first and second neck rings being supported from the turret with substantially 90.degree. separation in a plane parallel to the plane of the circle and the first and second blow heads being supported from the turret with substantially 90.degree. separation in a plane parallel to the plane of the circle, and each of the first and second neck rings being disposed substantially diametrically opposite one of the first and second blow heads on the turret.
