Abstract

An apparatus (10) is provided for producing continuous glass filaments (30). The apparatus (10) comprises a bushing (20) for supplying streams of molten glass and a drawing device (40) adapted to draw the streams into continuous glass filaments (30). A cooling device (50) is also provided and is located adjacent to the bushing (20) for drawing in heated air from a filament forming area beneath the bushing such that heat is convectively transferred away from the filament forming area.
