ABSTRACT:
The present invention embraces apparatus for the production of mineral fibers. A bushing for the manufacture of mineral fibers, such as glass fibers, comprises an orificed bottom wall for the passage of streams of molten mineral material therethrough for attenuation into fibers, upwardly extending sidewalls and an orificed member, positioned above the bottom wall and extending between the sidewells, for passage of the molten mineral material therethrough to the bottom wall. The ratio of the poiseuille resistance to flow of the orificed member to the poiseuille resistance to flow of the bottom wall is in the range of from about 0.5 to about 1.0.
