Abstract of the Disclosure A method and apparatus wherein there is provided a source of fiber forming material, with said fiber forming material being pumped into a die having a plurality of spinnerets about its periphery. The die is rotated at a predetermined adjustable speed, whereby the liquid is expelled from the die so as to form fibers. It is preferred that the fiber forming material be cooled as it is leaving the holes in the spinnnerets during drawdown. The fibers may be used to produce fabrics, fibrous tow and yarn through appropriate take-up systems. The pumping system provides a pumping action whereby a volumetric quantity of liquid is forced into the rotational system independent of viscosity or the back pressure generated by the spinnerets and the manifold system of the spinning head, thus creating positive displacement feeding. Positive displacement feeding may be accomplished by the extruder alone or with an additional pump of the type generally employed for this purpose. A rot?ry union is provided for positive sealing purposes during the pressure feeding of the fiber forming material into the rotating die.
