(54) Spinning winder


(57) 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.
