(54) Winding unit, automatic winder and aligning method of yarn supplying bobbin


(57) A winder unit (winding unit (4)) includes a bobbin holder (110) holding the yarn supplying bobbin (21), a length information acquiring section acquiring length information, which is information related to an axial length of the yarn supplying bobbin, a position detecting section (74) capable of detecting the position of the yarn supplying bobbin held by the bobbin holder, a storage section (52) storing information of an unwinding standard position and information of a position where the position detecting section is arranged, and a unit control section (50). The unit control section carries out control of moving the position detecting section so that the position detecting section can detect the yarn supplying bobbin held by the bobbin holder based on the length information, and control of moving the yarn supplying bobbin to align the yarn supplying bobbin with the unwinding standard position based on the length information and a storage content of the storage section.
