A yarn slack eliminating device includes a roller 42. A winding range 60 of the roller 42 around which a yarn is wound is formed in a taper shape in which a diameter decreases from an upstream side where the yarn starts to be wound around towards a downstream side. The winding range 60 includes a first taper section 62 and a second taper section 63, and a taper angle becomes moderate towards the downstream side in two stages at the first taper section 62 and the second taper section 63. An area of the first taper section 62 having a large taper angle is smaller than an area of the second taper section 63 having a small taper angle ( Fig. 4 ). |
