関する。DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a spinning cooling cylinder used when melt spinning a fiber-forming polymer. More specifically, the present invention relates to a cross-flow type cooling cylinder which is annular and in which the direction of airflow in the cooling cylinder is directed inward from the periphery of the yarn bundle.

するという欠点があった。However, conventionally, as disclosed in Japanese Patent Publication No. 53-22568, a type in which the air introduction pipe is directly connected to the opening of the cooling cylinder has been used, and in this method, the air introduction pipe side and the It is not possible to maintain a uniform cooling air velocity on both the inlet pipe side and the threads sway excessively.
This causes fusion and increases the rate of variation in fineness. In addition, the cooling spots cause a significant difference in the degree of orientation of the weaving yarns, resulting in large variations in the strength and elongation characteristics of the weaving yarns, resulting in a drastic increase in troubles in the drawing process and a significant drop in productivity. there were.

表わされる範囲内に設定することが好ましい。In the figure, 1 air introduced from the outside is air introduction pipe 1.
It passes through the inside and hits the outer wall 5 of the cooling cylinder. That is, the air from the outside uses the baffle plate effect of the outer wall 5 of the cooling cylinder to reduce unevenness in wind speed in the air introduction pipe as much as possible, and then the uniform air passes through the opening 6 of the cooling cylinder, and the air is evenly distributed in the cooling cylinder. It is configured so that it is guided to the pressure zone 4. 1 here. The distance between the lower end 3 of the air introduction pipe and the upper opening #2 of the cooling cylinder is preferably set within the range expressed by the following formula.
