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.
