Abstract

It is an object of the present invention to provide a spinning machine that enables the elimination of slack that may occur between a spinning device that spins a yarn and a winding device that winds a yarn. A yarn slack eliminating device for a spinning machine comprises a slack eliminating roller 23 arranged so as to engage with a yarn spun by a spinning device of the spinning machine and winding a yarn Y around its outer peripheral surface 23a, driving means 24 for rotatively driving the slack eliminating roller 23, and a downstream guide 26 arranged downstream of the slack eliminating roller 23 to guide the yarn Y on a centerline of rotation A of the slack eliminating roller 23. The yarn slack eliminating device supplies the yarn to a proximal end B of the outer peripheral surface 23a of the slack eliminating roller 23 and then winds the yarn Y around the proximal end B, and unwinds the wound yarn Y from the slack eliminating roller so that the unwinding starts with a leading end D of the slack eliminating roller and moves toward the downstream guide 26. An upstream guide 25 is arranged upstream of the slack eliminating roller 23 and close to the proximal end B of the outer peripheral surface 23a of the slack eliminating roller 23 (Fig.4).
