ABSTRACT:
Process and apparatus are provided for producing filaments comprising: supplying a plurality of streams of molten material; attenuating said streams of material into continuous filaments through the action of a stream of fluid moving from an attenuation means; said filaments being entrained in said fluid moving from said attenuation means, moving said stream of fluid and filaments along a first surface positioned intermediate said attenuation means and a foraminous surface; establishing a vacuum at said foraminous surface; directing said stream of fluid and filaments into said foraminous surface obliquely oriented with respect to said first surface such that a first portion of said fluid separates from the filaments and passes through said foraminous surface and a second portion of said fluid moves said filaments along the foraminous surface; collecting said filaments.
