ABSTRACT:
Apparatus for fluidically attenuating streams of molten material into filaments is provided comprising; a base having a first chamber and a recess separated by a wall having a plurality of apertures therethrough, said first chamber being adapted to receive a fluid; a first member having a first arcuate surface and a distal end, the first member being adapted to be joined to said base such that first arcuate surface is adjacent said recess and said apertures of said base; a second member having a second arcuate surface, a head region, and a third arcuate surface, said head region being located intermediate and contiguous with said second and third arcuate surfaces, said second member being joined to said base such that said second arcuate surface is positioned adjacent said recess and said apertures of said base such that said first arcuate surface, said second arcuate surface and said head region form a smoothly converging passageway, the head region being positioned relative to the distal end to form an outlet through which said fluid is moved, said third arcuate surface being adapted to control the moving fluid issuing from said outlet, wherein the contraction ratio of the cross-sectional area of the inlet section to the cross-sectional area of the outlet section of the converging passageway is within the range of values from about 150 to about 750 to 1.
