Abstract: An apparatus for producing curly fibers from a molten stream which is pulled from a melt by high velocity attenuating fluid. The device includes a fiber forming feeder having orifices extending between a pair of elongate blowers which direct intersecting streams of high pressure fluid below the orifices to attenuate and cool the molten streams into fibers. Positioned below the orifices is a single skirt extending generally parallel to the direction of movement of the fibers and having a plurality of sinuous convolutions. High velocity air streams pulling the plastic fibers across the convolutions cause them to impinge against one or more skirt convolutions and to assume a curvilinear configuration prior to losing plasticity and leaving the skirt area. The skirt may be surrounded by a peripheral housing having air vents which permit the lateral entry of outside air pressure to further assure contact between the skirt and descending fibers.
