ABSTRACT:
A bushing assembly is provided which is adapted to be positioned beneath a forehearth (30) to receive a stream of molten glass flowing from the forehearth (30). The assembly comprises a glass receiving block (76), a bushing (50) and at least one cooling element (82). The receiving block (76) is positioned adjacent to the forehearth (30) to receive the stream of molten glass flowing from the forehearth (30). The receiving block (76) has an orifice (72) through which the molten glass passes. The bushing (50) receives the stream of molten glass from the glass receiving block and supplies a plurality streams of molten glass to be drawn into continuous glass fibers. The at least one cooling element (82) extends into the stream of molten glass and transfers energy in the form of heat away from the molten glass.
