Abstract
The present invention embraces a method of, and apparatus for, forming mineral fibers, such as glass, comprising flowing stream of molten mineral material from a stream feeder through a plurality of orificed projections depending from the feeder floor, attenuating fibers from the streams of molten mineral material, and directing gas upwardly into contact with the streams of molten mineral material at a velocity and in an amount effective to convey away from the streams sufficient heat to render the material of the streams attenuable to fibers without appreciably disturbing the ambient gas above the streams in the region of the orificed projections, the improvement comprising restricting the flow of gas adjacent the plate in the region of the perimeter of the plurality of orificed projections while leaving the directed gas free to flow in the region of the perimeter of the streams of material.
