Abstract
A glassware production system includes an electropneumatic individual section glass forming machine having a multiplicity of operating mechanisms for converting a gob of molten glass into a hollow glass container. A glass forehearth feeds molten gobs at controlled temperature and weight to the forming machine. Electronic controllers individually and selectively control parameters of operation of the multiplicity of machine mechanisms and the forehearth. Glassware from the forming machine is inspected for manufacturing faults and for identifying each inspected container with its associated mold of origin. The glassware inspection devices provide fault signals indicative of a plurality of differing types of faults, which are thereafter associated not only with mold or section of origin but also with fault cause. The differing types of fault signals are thus coordinated with associated operating parameters of the forming machine and forehearth, and such operating parameters are automatically varied at the machine and forehearth controllers to correct detected faults.
