ABSTRACT:
In an apparatus for producing glass fibers wherein an orifice plate formed with a greater number of orifice holes in high density is provided to draw glass fibers therethrough and air nozzle means is provided for impinging air flow against the undersurface of the orifice plate so that the adjacent cones of molten glass formed on the undersurface of the orifice plate may be prevented from coalescing to each other, an air nozzle assembly is provided which includes a plurality of tubular nozzles arranged in such a way that their discharge ports may be arranged in line and in parallel with the longitudinal direction of the array of orifice holes in the orifice plate and spaced apart from each other by a predetermined distance. High cooling efficiency may be attained with a less consumption of cooling air; the undersurface of the orifice plate may be uniformly cooled; the operation for separating a bead of molten glass formed on the undersurface of the orifice plate into individual cones may be facilitated; and the filament or fiber breakage due to the impingement of the air jets may be avoided.
