Abstract (en)

An object of the present invention is to reduce production loss due to a failure in yarn threading in a spun yarn take-up winder configured to wind yarns.A spun yarn take-up winder 3 of a spun yarn winding system 1 includes a bobbin holder 24 supporting bobbins B to be rotatable, a yarn detection unit 26 which is provided between a spinning apparatus 2 and the bobbins B in a yarn running direction and which detects yarns Y, and a winding controller 15. When the yarn threading is being performed, the winding controller 15 determines whether a failure in the yarn threading occurs in each yarn Y on the basis of a detection result of the yarn detection unit 26 before the yarns Y are threaded onto the respective bobbins B supported by the bobbin holder 24.
