Apparatus for forming filaments

摘要

Method and apparatus are provided for forming filaments comprising: means for supplying a plurality of streams of molten material; attenuation means for supplying of moving fluid to attenuate said streams into said filaments; said filaments being entrained in said fluid moving from said attenuation means; and means for separating said filaments entrained in said moving air comprising a foraminous surface having; (a) an intercept region oriented to form an acute angle between a path defined by the entrained filaments approaching said intercept region; and (b) a concave region contiguous with said intercept region oriented such that at least a portion of said concave region is positioned substantially transverse to said path such that a portion of said air passes through said foraminous surface and a portion of said air moves along said foraminous surface to move said filaments therealong.
