ABSTRACT:
A method and apparatus are provided for controlling the delivery of multiple gobs to the blank molds of a glass forming machine having multiple cavities or sections, wherein multiple gobs are delivered from a glass feeder to plural scoops that are oscillated to deliver the gobs in multiples to aligned troughs and funnels in a timed sequence. An infrared gob sensor at each exit detects passage of a gob, and a computer controls application of air under pressure to control the velocity of delivery of each gob to the scoops in order to influence gob exit timing at the deflectors that are positioned adjacent the mold cavities.
