た。(Prior Art) Conventionally, in order to manufacture a bushing plate, a bushing plate material 1 is first placed on a template 3 having a large number of holes 2 at regular intervals, as shown in FIGS. 4', push a part of the bushing plate material 1 into the hole 2 of the template 3 to form the protrusion 5,
5' and a conical recess 6 on the back side of the protrusion 5'. Next, as shown in FIG. 2c, a spinning hole 8 is formed at the bottom of the conical recess 6 formed on the back side of the protrusion 5' of the bushing plate material 1 by driving a punch 7 or by reaming. A nozzle 9 was formed and a bushing plate 10 was obtained.
（発明が解決しようとする問題点）
然し乍ら、斯かるブツシングプレートの製造方
法は、次のような問題点がある。(Problems to be Solved by the Invention) However, this method of manufacturing a bushing plate has the following problems.
(1) 第２図ａに示す如くポンチ４による塑性加工
で突起５を形成すると共に円錐状くぼみ６形成

さにばらつきが生じたりして品質を損なうもの
である。(1) As shown in FIG. 2a, when the protrusion 5 is formed by plastic working with the punch 4 and the conical depression 6 is formed, and then the punch 7 is punched in to form the spinning hole 8, the punch 7 may be slightly misaligned. The tip of the nozzle 9 is not driven straight, and the thickness of the nozzle 9 becomes uneven as shown in FIG. 2b. Therefore, when glass fiber is discharge-spun using the spinning hole 8 of such a nozzle 9, the fiber may break midway or the thickness of the thread may vary, which impairs quality.
(2) 小径の紡糸孔８（直径1.5mm以下）を穿設す

ので、次第に紡糸孔８に寸法誤差が生じるよう
になる。(2) Drilling a small-diameter spinning hole 8 (diameter 1.5 mm or less) wears out the punch 7 (or reamer), which gradually causes dimensional errors in the spinning hole 8.
そこで、本発明は、ノズルの肉厚を均一にで

ある。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a method for manufacturing a bushing plate in which the thickness of the nozzle can be made uniform and even small-diameter spinning holes can be easily formed.

糸孔が容易に得られる。(Function) As described above, in the method for producing a bushing plate of the present invention, a large number of spinning holes are arranged and bored in the bushing plate material, and the spinning holes are formed by penetrating hard balls having a diameter larger than the diameter of the holes. Therefore, if the thickness of the side wall of the spinning hole is uneven, the hard ball passes through the spinning hole while rotating. Therefore, uneven thickness of the side wall of the spinning hole is corrected, and a nozzle with a uniform wall thickness can be obtained. In addition, since hard balls are hard to wear and easy to replace, the dimensional error of the spinning hole is extremely small and a small diameter spinning hole can be easily obtained.
