本発明は紡糸口金に於ける突起ノズルの成形方
法に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming a protruding nozzle in a spinneret.
紡糸口金に於ける突起ノズルは、第１図に示す
如く突起５の先端面積が極小で且つ先端の曲率が
極小であることが必要である。 As shown in FIG. 1, the protrusion nozzle in the spinneret requires that the tip area of the protrusion 5 is extremely small and the curvature of the tip is extremely small.
ところで従来、紡糸口金に於ける突起ノズルを
成形するには、先ず第２図ａに示す如く紡糸口金
１の紡糸面板２に多数のノズル孔３（図では２個
のみ示してある）を切削し、次に第２図ｂに示す

記紡糸孔４を開口して突起ノズル６を成形してい
た。 Conventionally, in order to form a protruding nozzle in a spinneret, first a large number of nozzle holes 3 (only two are shown in the figure) are cut in the spinning face plate 2 of the spinneret 1, as shown in FIG. 2a. Next, as shown in FIG. 2B, a thin spinning hole 4 is formed at the tip of the nozzle hole 3 using a punch, and a protrusion 5 is formed on the spinning surface 2a, and then the tip of the protrusion 5 is polished as shown in FIG. 2C. Then, the spinning hole 4 was opened to form a protruding nozzle 6.

糸孔４を開口した突起５の先端面の面積にもばら
つきがある。 For this reason, when cutting a large number of nozzle holes 3, the second
As shown in figure a, the spinning surface 2a is
Due to variations in the thickness of the fibers, the sizes of the protrusions 5 formed on the spinning surface 2a as shown in FIG. 2B are different, and for this reason, the spinning holes 4 are opened by polishing as shown in FIG. 2C. There are also variations in the area of the tip surfaces of the protrusions 5.
従つてこのような突起ノズル６を有する紡糸口

るものである。 Therefore, in a spinneret having such a protruding nozzle 6, the wettability of the periphery of the spinning hole 4 varies, and in the case of a protruding nozzle 6 in which the area of the tip surface of the protrusion 5 is large during spinning, the molten polymer does not coat the periphery of the spinning hole 4. It adheres to the thread and gradually accumulates, causing thread breakage.
本発明はかかる問題点を解決する為に、紡糸孔
を開口せる多数の突起の先端面の面積をそろえる
ことのできる突起ノズルの成形方法を提供せんと
するものである。 In order to solve this problem, the present invention aims to provide a method for forming a protrusion nozzle in which the areas of the tip surfaces of a large number of protrusions that open a spinning hole can be made uniform.
以下本発明による紡糸口金に於ける突起ノズル

多数の突起５の先端を研磨して前記各紡糸孔４を
開口して突起ノズル６を成形する。 A method of forming a protruding nozzle in a spinneret according to the present invention will be explained below with reference to FIGS. 3a to 3e.
First, as shown in FIG. 3a, the spinning face plate 2 of the spinneret 1 is
A large number of nozzle holes 3 (only two are shown in the figure) are cut. Next, as shown in FIG. 3b, each nozzle hole 3 is punched to eliminate variations in cutting. Next, the spinning surface 2a is polished and smoothed by punching as shown in FIG. 3C in order to eliminate the bulge 2b protruding from the spinning surface 2a. Next, using a punch, as shown in FIG. 3d, a narrow spinning hole 4 is formed at the end of each nozzle hole 3, and a protrusion 5 is formed on the spinning surface 2a. Thereafter, as shown in FIG. 3e, the tips of the numerous protrusions 5 on the spinning surface 2a are polished to open the respective spinning holes 4 and form protruding nozzles 6.

いう優れた効果がある。 In the method for forming a protruding nozzle of the present invention, by punching each nozzle hole 3 that was originally cut, variations in the thickness from the tip of each nozzle 3 to the spinning surface 2a as shown in FIG. 3b can be eliminated. A bulge 2 generated on the spinning surface 2a due to the punching
b is smoothed by polishing the spinning surface 2a as shown in FIG. When formed, the heights of the protrusions 5 are equal, so that the tips of the protrusions 5 are finally polished uniformly to open the spinning holes 4, as shown in Fig. 3e. This has the excellent effect that an ideal protruding nozzle 6 as shown in FIG. 1 can be formed, with the surface area being uniform and extremely small, and the curvature of the tip being extremely small.

ないものである。 Therefore, in a spinneret having such a protruding nozzle 6, the wettability of the periphery of each spinning hole 4 is uniform and good, so that molten polymer does not adhere or accumulate on the periphery of the spinning hole 4 during spinning, and yarn breakage is prevented. It is something that never occurs.
