ABSTRACT:
A single mold and plunger set is programmed to form a parison within each of a plurality of neck rings which are continuously successively presented along a linear path. The mold, which is positioned below the linear path of said continuously successively presented neck rings, receives a charge of molten glass and accelerates in a direction parallel to said linear path to a speed commensurate with that of the continuously presented neck rings, and upon tracking with a particular neck ring, such mold moves vertically into engagement with a bottom portion thereof. Simultaneously, the plunger, which is positioned above said linear path, accelerates in a direction parallel with the movement of said continuously presented neck rings to a speed commensurate therewith, and upon tracking said particular neck ring moves vertically into engagement with an upper portion thereof so as to press form the charge of molten glass deposited within the mold into a shape determined by the shape of the parison mold and plunger. The mold and plunger then retract from said particular neck ring, which retains the parison therein, and return to the starting position to repeat the cycle so that a parison may be press formed in the next succeeding neck ring.
