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.
Claims9
A method of manufacturing glass containers on a stationary, individual section bottle machine having a parison forming position and a blow mold position including, in combination, introducing a gob of molten glass into a parison forming device, forming a glass parison, cooling the glass parison, transferring the parison to a station intermediate to the parison forming position and the blow mold position the intermediate station being spaced from and exterior to both the parison forming station and the blow mold station, mechanically stretching the parison to a desired length while it is at the intermediate station, transferring the elongated parison to a blow mold, having a blow mold cavity, and expanding and cooling the parison to form a glass container.
