Method for producing rotary textile fibers

A method of making glass fibers in a rotary centrifuge having a peripheral wall, a plurality of orifices in such wall and an axis of rotation, comprising the steps of discharging and attenuating streams of molten glass fibers from the rotary centrifuge along paths generally perpendicular to such axis of rotation, turning the glass fibers down in a direction generally parallel to such axis of rotation and prior to such turning down quenching said fibers at a location exterior of the centrifuge, at a position to temper the fibers into high strength textile fibers, by the application of a quenching liquid while such fibers are in paths generally perpendicular to such axis of rotation, wherein such quenching liquid is applied in the range of 0.2 lb. to 1.2 lb. (0.09 kg. to 0.54 kg. of liquid) to 1 lb. of glass (0.45 kg of glass).
