(54) YARN WINDER


(57) The efficiency in yarn threading is improved when yarn threading to yarn guides of a pair of winding units is performed. Each of paired winding units 5 of a spun yarn take-up machine 1 includes fulcrum guides 20 aligned in a front-rear direction. The spun yarn take-up machine 1 includes a yarn threading mechanism 30 configure to perform yarn threading to the fulcrum guides 20. The yarn threading mechanism 30 includes paired holding units 31 which are provided to correspond to the respective winding units 5 and are configured to hold respective groups of yarns Y and a drive mechanism 32 configured to the move the paired holding units 31. The drive mechanism 32 moves the paired holding units 31 from capturing positions where the yarns Y can be captured to yarn threading start positions that are rearward of the capturing position and further moves the paired holding units 31 to yarn threading completion positions that are forward of the yarn threading start positions, so as to thread all of the yarns Y to the fulcrum guides 20.
