Abstract (en)

A yarn winding machine (1) winds yarn of a yarn feeding bobbin (B) transferred from a spinning frame (2) by a bobbin transfer device (3) to form a package (P), and includes a controller (17). When a partial defect has occurred in the yarn of the yarn feeding bobbin (B) in the spinning frame (2), the controller (17) acquires first yarn-defect information prepared by the spinning frame (2) about the occurrence of the partial defect. The controller (17) stops winding of the yarn from the yarn feeding bobbin (B) upon determining that the yarn has been unwound from the yarn feeding bobbin (B) up to a position corresponding to the partial defect of the first yarn-defect information, based on yarn information of the yarn wound from the yarn feeding bobbin (B) related to the first yarn-defect information acquired and the first yarn-defect information prepared by the spinning frame (2), when the first yarn-defect information of the yarn feeding bobbin (B) has been acquired.
