ABSTRACT:
A method and apparatus are disclosed for forming a stream of cut filaments from a source of tangled, non-oriented filaments. A feeder ram is movable between a feed position and a load position for directing filaments from the source of non-oriented filaments into interfering relation with advancement of a cutter ram. The cutter ram is movable between a load position and a cut position for directing at least a portion of the filaments, which are in interfering relation with advancement of the cutter ram, against at least two blades. Fibers directed against the blades are cut to form, with remaining filaments which are not cut, a stream of cut filaments. The blades can be configured for continuous sharpening of blade edges during cutting.
