Therefore, the small protrusions do not extend to both sides beyond the range of the shape of the irregularly shaped spinning hole.Therefore, the opening edge of the irregularly shaped introduction hole does not sag, and then the small protrusion spreads to the bottom of the irregularly shaped introduction hole. Since the inside of the introduction hole is not deformed even if an irregularly shaped discharge hole is processed, there is no unevenness in the capillary length in the cross section of the spinning hole, and accuracy is improved.

た。(Example) An example of the method for processing a deformed spinneret of the present invention will be described with reference to the drawings.
Inner diameter 59.3mm, depth 10mm, flange outer diameter 70m
A dish-shaped spinneret material 1 of 50 mm is formed by concentrically multiplying rectangular recesses 2' in an annular manner as shown in FIG. Place the base material 1 at a predetermined position on the base 3', and use the forming punch 4 to sequentially form rectangular introduction holes 5 in the base material 1 at the positions of the rectangular recesses 2' to form a base material 1 as shown in FIGS. 2a and 2b. The small protrusions 6 formed on the lower surface of the material 1 are held in the rectangular recess 2' of the base 3', and then the base material 1 is removed from above the base 3' and the small protrusions 6 formed on the lower surface are removed by polishing. Then, as shown in FIGS. 3a and 3b, the base material 1 is again placed on the base 3' and set in a predetermined position, and the introduction hole 5 is opened with a reamer (not shown).
A rectangular discharge hole 7 is sequentially machined on the bottom of the base material 1, and the burr 8 generated at the opening edge of the discharge hole 7 on the lower surface of the base material 1 by machining the discharge hole 7 is removed by polishing as shown in FIGS. 4a and 4b. Thus, an irregularly shaped spinneret IO having a rectangular spinning hole 9 was manufactured.

精度が向上した。As described above, in the embodiment of the present invention, the rectangular introduction hole 5 in the base material 1 is processed by the forming punch 4 to form the base material l.
Since the small protrusions 6 formed on the lower surface of the rectangular spinning hole 9 are held in the recess 2' having the same shape as the rectangular spinning hole 9, the small protrusions 6 can extend to both sides beyond the range of the rectangular spinning hole 9. There is no Therefore, the middle part of the opening edge of the rectangular introduction hole 5 does not sag, and when the rectangular discharge hole 7 is subsequently machined at the bottom of the rectangular introduction hole 5, the inside of the introduction hole 5 does not deform.
There is no unevenness in the capillary length in the cross section of the spinning hole 9,
Improved accuracy.
