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.

Abstract: The present invention provides yarn winder that can provide a vibration suppressing function for the yarn winder over a long period despite minor differences in vibration characteristic among individual yarn winders. A vibration suppressing device is provided in a yarn winder comprising rotatable bobbin holders 105 and 106 supported on a body frame 102, the bobbin holders each having bobbins installed thereon and around which packages P are formed. The vibration suppressing device comprises an impact damper 10 comprising a mass body 11 and a regulation member 13 for holding the mass body 11 in such a manner as to have degrees of freedom. The impact damper 10 is provided in a site that vibrates as the bobbin holders 105 and 106 rotate, for example, at a tip of an elevating bracket 109.

Abstract: It is an object of the present invention to provide a take-up winder for filament yarn capable of relating the device for bobbin holder such as a compressed air supplying device or a rotating speed measuring device, to the change in the position of the bobbin holder.

Abstract: An elastic yarn winding method for winding an elastic yarn in succession by a plurality of bobbin holders, and for transferring a continuously running elastic yarn from a full bobbin to an empty bobbin. The method comprises steps of putting, along a surface of the empty bobbin in some area, the elastic yarn between the full bobbin and the empty bobbin, and of contacting the elastic yarn between the full bobbin and empty bobbin with the elastic yarn present at the upstream side of the empty bobbin. A winder for processing the method provides a yarn transfer device for winding the elastic yarn on the empty bobbin and for holding the elastic yarn in contact with the elastic yarn present at the upstream side of the empty bobbin.

Abstract: A yarn take-up machine capable of decreasing vibration at the time of elevating frame resonance and operating at a wide range of take-up speeds from low to high speeds. Bobbin holders for holding a bobbin to package winding are mounted on a machine frame and a frame member for holding a touch roller rotating in contact with the bobbin holders is supported on the machine frame. In this take-up machine, a dynamic vibration absorber is mounted in the vicinity of the forward end of the frame member.
