Abstract

PURPOSE: To obtain protruded orifices of equal height free from breaking fibers, by punching orifices to equalize the depth, and by forming the protruded ones at the tips of the orifices.
CONSTITUTION: A plurality of orifiecs 3 are bored through the spinneret plate 2, and then punched to eliminate the variation in the depth. The surface 2a is ground to remove the protuberances 2b from the surface 2a. The fine orifieds 4 are provided at the tips of the orifices 3 to form the protrusions 5 on the surface 2a. The tips of the protrusions are ground to give the protruded orifices 6.
EFFECT: Free from adhesion or deposition of molten polymers around the orifices.
