Abstract
A spun yarn winding device includes a machine body; a turret; a feeding roller that is fixed to the machine body, is not in contact with winding bobbins, and feeds yarns to the winding bobbins at a speed equal to or faster than a winding speed; a traverse device fixed at an upstream side of an advance direction of the yarns relative to the feeding roller and which traverses the yarns; a peripheral speed detection unit that detects a peripheral speed of the winding bobbins; and a control unit that is arranged and programmed to perform a basic operation to maintain a free length of the yarns at a standard length by controlling a rotational angle of a turret during a yarn winding period, the free length of the yarns being located between the feeding roller and the winding bobbins.
