[Problem to be Solved] An object is to provide a yarn winding apparatus in which a contact roller is supported so as to be swingable about a body, wherein vibration of a swing arm is suppressed without spoiling function of the contact roller to add contact pressure. [Solution] A swing arm 31 supported on a body 10 by a swing shaft 32 and swingable around the swing shaft 32, a contact roller 33 supported by the swing arm 31 and contacting a package P formed on winding bobbins B with which a bobbin holder 21 is equipped, and a vibration suppression device 60 which has a mass object 61 and a restriction member 63 supporting the mass object 61 with flexibility and is provided in the swing arm 31 so that the mass object 61 and the restriction member 63 collides each other by vibration of the swing arm 31 are provided. A component of the flexibility of the mass object 61 is provided at least within a plane perpendicular to the swing shaft 32 of the swing arm 31 and in circular direction centering on the swing shaft 31.

Damage on yarns is restrained while allowing the bending angles of the yarns at distribution guides by which the yarns spun out from a spinning unit are distributed to be large. Yarns 10 serially spun out and supplied from a spinning machine are conveyed to a winding unit below by two godet rollers, and in a winding unit the yarns 10 are distributed by fulcrum guides 13 and then wound onto bobbins attached to a bobbin holder. Each fulcrum guide 13 is a column having a radius of not shorter than 3mm and not longer than 8mm, and the yarn 10 is threaded on the outer circumference of the fulcrum guide 13. By rotating the fulcrum guide 13, the sliding position between the fulcrum guide 13 and the yarn 10 is changed. Furthermore, the movement of the yarn 10 threaded on the fulcrum guide 13 is restrained in the axial directions of the fulcrum guide 13, because the yarn 10 is arranged to pass through a slit 25a made through a restraining guide 25 which is provided above the fulcrum guide 13.

All yarns are surely cut and sucked irrespective of the number of the yarns. A yarn cutting-sucking device 40 includes a cutter 43 arranged to be movable in the alignment directions of yarns Y, a sucking unit 41 which is provided in proximity to the cutter 43 and includes a sucking pipe 45 which is movable in the alignment directions in the same manner as the cutter 43, and a cylinder 46 which is arranged to move the sucking pipe 45 along the alignment directions. As the cylinder 46 is driven, the cutter 43 and the sucking pipe 45 move in an alignment direction in a synchronous manner.

[Object] Object of the invention is providing yarn threading method of take-up winding apparatus, the take-up winding apparatus, and suction gun which make decrease entanglement between yarns and vibration and make good for take-up yarns. [Solution means Purpose] A method for threading to a take-up winding apparatus using a suction gun includes regulating yarn paths for a plurality of yarns using a first roller 21 or a first yarn path guide 22 of the take-up winding apparatus. Between the suction gun 61 and a second roller or a second yarn path guide 23 of the take-up winding apparatus, a third roller 24 is brought into contact with the yarns Y. The second roller and the second yarn path guide 23 are on a downstream side relative to the first roller 21 and the first yarn path guide 22. With the third roller 24 in contact with the yarns Y, the yarns Y are fed onto the second roller or the second yarn path guide 23. After the yarns are fed onto the second roller or the second yarn path guide 23, the third roller 24 is brought out of contact with the yarns Y.

Yarns threaded on a godet roller are fed to corresponding distribution guides by a simple structure. A spinning winder includes components such as two godet rollers 11 and 12 receiving yarns 10 supplied from a spinning machine, fulcrum guides 13a to 13d which are aligned in crosswise directions along a bobbin holder and distribute the yarns 10 wound onto the downstream-side godet roller 12 to bobbins attached to the bobbin holder, respectively, and a yarn threading guide 20 which is arranged to be movable in the alignment directions of the fulcrum guides 13a to 13d between the fulcrum guides 13a to 13d and the bobbin holder, while holding the yarns 10.
