Abstract
A method and apparatus for forming glass fibers is disclosed. The method of the present invention involves passing a narrow, high velocity air stream horizontally below the bushing to thereby induce and entrain additional air flow from the environment surrounding the bushing into this air stream to flow generally horizontally below the bushing. Suitable apparatus, such as an air amplifier, is employed to produce this desired result.
