A method and apparatus for automatically stopping an automatic glassware forming machine in an orderly sequence of steps. When it is desired to start the machine, a start routine is initiated to move the various glassware forming mechanisms into the appropriate starting positions such that the glassware forming cycle can begin. A stop routine is provided to cycle the glass from the machine and to move the various glassware forming mechanisms into a stationary position where they can be easily accessed. In accordance with the present invention, if the stop routine is intiated before at least one predetermined exit point in the start routine, the stop routine will be entered at an intermediate step such that only those steps concerned with moving the forming mechanisms into the final stationary position will be performed.

Automatic stop routine for a glassware forming machine

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.
