ABSTRACT:
Method and apparatus for forming glass containers by the blow and blow process in which a parison mold and blow mold are positioned relative to each other, such that parisons can be transferred by an invert arm. The parisons are formed with their necks down in the parison mold from a charge of glass delivered thereto, and vacuum is applied to the neck mold to settle the molten glass in the neck mold about a special neck pin to thereby form the finish portion of the container. The neck pin is pulled and counterblow of the charge into parison form is accomplished and the parison is transferred from the parison mold to the blow mold where it is expanded into final shape. The parison mold is coated with a "solid film lubricant" which provides a surface that has an insulating effect and requires less "swabbing" over its useable life. A plunger that has a tip that produces less heat removal for the time it is in contact with the charge or gob of glass is used and purging of the vacuum passages in the plunger is carried out each cycle.
