Abstract

PURPOSE: To obtain the title spinneret having a high concentricity of orifices and water or gas outlets, by machining the periphery of the nozzle tip and the inner surface of the polymer outlet simultaneously to form an orifice, and by boring and communicating a blind hole for water or a gas.
CONSTITUTION: The nozzle 8 having the blind hole 6 for water or a gas at the center and a plurality of polymer ports 7 is fixed in the holder 10 with the central polymer outlet 9. The periphery of the nozzle tip and the inner surface of the polymer outlet 9 are finished simultaneously by spark erosion using the hollow electrode 14 in alignment with the spinneret tip to give the orifice 9'. The water or gas outlet 16 is bored at the center of tip by spark erosion using the cylindrical electrode 15, in alignment with the tip, to open and communicate the blind hole 6 for water or a gas.
