The cross section of the groove 1 is shown in FIG. 3, and the surface roughness of the groove surface is 5S, β is 25 °, γ is 20
2, the total length of the guide 3 in the direction perpendicular to the yarn in FIG. 2 is 26 mm, the apex 5 is 0.6 mmr, dH is 3.5 mm, and dL is 3.0 mm. The minimum width of the groove in the narrowest portion 8 is 2.5 mm, and the maximum diameter of the opening 5 is 2.8 mm in the width direction of the groove. Using the oil application device having this guide, polyurethane elastic yarn was spun at a predetermined spinning speed so as to have 40 denier and 5 filaments. Example [2]: All steps were performed in the same manner as in [1] except that the surface roughness of the groove was 25S. As a comparison, a roller type and a guide type disclosed in US Pat. No. 4,329,750 were used, and all other conditions were the same. All the oil adhesion amounts were 6% by weight (relative to the yarn). The uniformity of the elastic yarn obtained at this time was measured with an EVENESTESTER KET80C manufactured by Keisoku Kogyo Co., Ltd.
Was evaluated. The spinning operability was evaluated based on the number of yarn breaks per 120 hours.

This means that fluctuations in the position of the yarn are suppressed and the finish (oil) is applied before the yarn comes into contact with the solid surface to control the position fluctuations and to apply the finish. Thus, the friction of the yarn is reduced and uniform, so that the yarn has extremely uniform properties.
