Abstract
A method and apparatus for automatically producing a frozen parison sample in an automatic glassware forming machine which includes a blank mold station for receiving a gob of molten glass for forming a parison in a first portion of a predetermined sequence of steps and a blow mold station for receiving the parison and completing the formation of the glassware in a second portion of the predetermined sequence of steps. When an operator requests a frozen parison sample, a control means automatically alters the first portion of the predetermined sequence of steps by extending the time the parison typically remains in the blank mold such that the parison freezes. The frozen parison sample is then transferred to the previously disabled blow mold station where it can be subsequently removed for inspection.
