ABSTRACT:
An apparatus for detecting the presence of a gob of molten glass as it enters a cavity in the mold of an automatic glassware forming machine. The detector includes a phototransistor sensor and circuitry for generating a gob detection signal. Two or more detectors can be combined to generate a signal indicating that the last gob has entered a multi-cavity mold so that the forming process can begin. The gob detection signal can also be utilized to adjust the timing of the glassware forming process for differences in the travel time between the gob forming apparatus and the mold.
