Abstract: The present disclosure is directed to an improved method and apparatus for making glass containers. A gob of molten glass is introduced into a parison forming device at the parison forming position. A glass parison is formed, cooled and transferred to an intermediate position where it is allowed to reheat and mechanically stretched to a desired length, while at temperatures between 1200.degree. F. and 2000.degree. F. The elongated parison is transferred to the blow mold position, expanded and cooled to form a glass container.

Abstract: A method and apparatus for manufacturing glass bottles and more specifically an apparatus and a method for forming parisons is disclosed. At least one blank mold defines a mold cavity having an opening at its upper end for receiving a premeasured gob of molten glass from a loading cavity member. A plunger having a volume of at least 15% of the volume of the mold cavity is completely extended into the mold cavity prior to the reception of the molten glass. The molten glass is moved downwardly from said loading cavity member into the mold cavity. Fluid force presses the molten glass against the walls of the mold cavity and against the extended plunger. The opening in the mold is closed by a baffle and the plunger retracted. Compressed air is applied through the neck of the parison to expand the parison outwardly against the mold cavity and a mold surface defined by the baffle means. The parison is then separated for further processing in the bottle making operation.
