ABSTRACT:
A molten glass feeder system and method of controlling the flow of glass through the feeder to deliver a plurality of uniform, molten glass gobs. The feeder has a heavy-walled bowl structure and a heavy-walled bottom transitional member mounted within the lower region of the feeder bowl, the transitional member having substantial height with a circular passageway at its upper region and an elongated slot passageway at its lower region, and an elongated discharge orifice member having a plurality of three or more, and preferably three to six, discharge orifices in lineal alignment with the elongated slot passageway. The feeder permits the simultaneous formation and delivery, when coupled with suitable glass shearing mechanism, of more uniform plural glass gobs having similar weight, temperature and heat characteristics to multiple-cavity gob-fed glass forming machines.
