Abstract (en)

A yarn is successfully threaded into a slit when a bobbin to which the yarn is wound is switched to a new bobbin, even if the length of the bobbin has a dimensional error from a predetermined standard size. A yarn threading mechanism 30, which is configured to thread a yarn into a slit S formed in the outer circumferential surface of each of new bobbins B when bobbins B on each of which a yarn is wound are switched to the new bobbins B, includes guides 31 which are provided to correspond to the respective bobbins B, are movable in an axial direction, and each threads a yarn into the slit S, a driving unit 32 configured to move the guides 31 in the axial direction, and a bobbin position sensor 22 configured to detect the position in the axial direction of a predetermined part of the bobbins B. Based on a detection result of the bobbin position sensor 22, the driving unit 32 is controlled so that the positions of the guides 31 are adjusted in the axial direction.
