ールむら等が発生することがあった。(Problem to be Solved by the Invention) By the way, in the above polishing method, since the spinning surface 2 of the donut-shaped spinning nozzle 1 has an arc shape in the width direction (the radial direction of the donut), the sand vapor 3 , and the position of the donut-shaped spinning nozzle 1 must be moved, resulting in poor workability. Furthermore, in order to perform rough polishing, medium polishing, and final polishing, the required sand vapor 3 must be attached to the rotating jig 4 each time, and the sand vapor 3 must be replaced frequently, resulting in poor polishing efficiency. Furthermore, the spinning surface 2 may be scratched due to clogging of the sand vapor 3 or discolored due to burning. Furthermore, since polishing work requires skill, inexperienced workers may end up polishing insufficiently or overpolishing, making it difficult to maintain consistent quality. In particular, the straight lengths of the spinning holes may become uneven, resulting in uneven spinning during use, resulting in yarn breakage, uneven denier, etc.

It is an object of the present invention to provide a method for polishing a spinning surface.

とするものである。(Means for Solving the Problems) A method for polishing the spinning surface of a donut-shaped spinning nozzle according to the present invention for solving the above-mentioned problems includes rotating a donut-shaped spinning nozzle and applying a roll-type polishing sheet to the spinning surface of the donut-shaped spinning nozzle. The method is characterized in that the spinning surface is polished with a roll-type polishing sheet by continuously feeding out the spinning material and pressing it with a hard rubber backup roll, and swinging the backup roll in both directions.

生も無い。(Function) As described above, the method of polishing the spinning surface of the donut-shaped spinning nozzle of the present invention has good workability because the spinning surface is polished by continuously feeding out a roll-type polishing sheet, and it does not require the conventional method. Since there is no need to replace the sandpaper every now and then, the polishing efficiency is high, and the spinning surface is always polished with new abrasive grains, resulting in stable polishing. In addition, since the rolled abrasive sheet is held down by a hard rubber backup roll, it conforms well to the curvature of the spinning surface in the width direction, and also has a buffering effect. Furthermore, since the backup roll is swung to both sides and the spinning surface is polished with a roll-type polishing sheet, the spinning surface becomes a crosshatch-like uniform surface with no directionality, eliminating uneven polishing and causing scratches. There is no.

前記紡糸面２を研摩シート３′にて研摩した。(Example) An example of the method for polishing the spinning surface of the donut-shaped spinning nozzle of the present invention will be described. As shown in Figure 1, it is donut-shaped with an outer diameter of 240 mm and an inner diameter of 169 mm, with a hat-shaped cross section and a depth of 1.
0mm, wall thickness 1.01111111 flange width 12mm
A spinning nozzle 1 made of stainless steel is rotated at 1100 rp, and a spinneret with a width of 60 mm and a thickness of 1.25 mm is placed on the spinning surface 2.
Al1203 abrasive grains (9μ
A roll-type abrasive sheet 3' coated with hard rubber (rubber hardness 40) is continuously rolled out.
Backup roll 5 with a diameter of 60 mm and a width of 60 mm
At the same time, the backup roll 5 is assisted by 3 mm on both sides at a rate of 100 times per minute.
The spinning surface 2 was polished with a polishing sheet 3'.

There wasn't. When this doughnut-shaped spinning nozzle was used, since the straight length of the spinning hole was constant, uneven spinning did not occur, and yarn breakage, uneven denier, etc. did not occur.
