ABSTRACT:
This invention relates to a method and apparatus for forming glass fibers. The invention comprises flowing streams of molten glass from a stream feeder through orificed projections depending from the feeder floor, directing gas upwardly into contact with the streams of molten glass at a velocity and in an amount effective to convey away from the streams sufficient heat to render the glass of the streams attenuable to fibers without appreciably disturbing the ambient gas above the streams in the region between the orificed projections and attenuating fibers from the streams of molten glass.
