A method of producing glass fibers is disclosed in which two streams of air are introduced into contact with the newly formed strands, one stream being introduced between the bushing and the size applicator and a second stream being introduced between the applicator and the gathering shoe.

Method for forming glass fibers

Two horizontally spaced parallel shafts (27,28) are rotatably mounted on a base plate (24) having an aperture (27a) therethrough. Each shaft has a plurality of rows of radially extending fingers (36). A casing (38,40) around the fingered portions of the shafts has an inlet throat (44) for receiving shopped strands (16). The shafts are operatively connected by a pair of gears (32,34), and a motor (30) connected to one of the shafts drives the shafts to move the fingers upwardly between the shafts for breaking up clumps of strands and carrying strands of a desired chopped length around the outer sides of the shafts for exit through the aperture. Excessively long strands become wrapped around one or the other of the shafts.
