C-14483 METHOD FOR FORMING GLASS CONTAINERS ABSTRACT OF THE DISCLOSURE Method for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities, The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container. A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is the opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape. During the transfer of the parisons from the parison mold to the blow mold, air under pressure is maintained within the hollow interior of the pari- son, The parison transfer is carried out by the neck molds with parison counterblow pressure delivering means as well as puff or low pressure means for either puffing the parison during its invert movement from the parison mold to the up- right position at the blow mold or to help sustain the parison against collapse during invert, The ability to apply puffing air to the parison during transfer is 2 significant step in the forming process.
