Feeder.

摘要

A feeder for a glass container forming machine comprising a spout bowl (11) including a vertically extending neck portion (32) having a vertical discharge passage through which molten glass will continuously flow to leave the spout bowl. An orifice plate (36) forms the molten glass leaving the passage into a selected number of runners which are sheared into discrete gobs of molten glass. A heater (56) heats the neck portion to decrease the wall shear stress of the molten glass flowing along the passage to increase the weight of a formed gob, and a cooler (60) cools the neck portion to increase the wall shear stress of the molten glass flowing along the passage to decrease the weight of a formed gob. <IMAGE>
