ABSTRACT:
A bushing environment control assembly for use with a glass fiber filament forming device is disclosed. The assembly controls the environment in the attenuation zone immediately below the glass fiber forming bushing's tip plate, the area in which the molten glass is attenuated and formed into filaments. A fin cooler assembly is secured beneath the tip plate and is provided with both liquid and gaseous coolant mediums. The coolant gas is directed into the zone adjacent the fiber forming tips from a plenum chamber in the fin cooler assembly. Additional coolant gas is directed downwardly parallel to the attenuated strands. The fins of the fin cooler are also adjustable with respect to the tip plate.
