Abstract (en)

Formation of straight winding on a bobbin is prevented when yarn threading onto the bobbin is performed. A yarn threading apparatus 60 includes: a yarn threading arm 62 having a yarn engagement portion 62a; and a bunch guide 65. A yarn Y is disengaged from the yarn engagement portion 62a on account of yarn threading to a hook 41a, when the yarn threading arm 62 is at a yarn threading position. The bunch guide 65 holds the yarn Y disengaged from the yarn engagement portion 62a to maintain the yarn Y at a bunch winding position x which is outside a traversal range of a bobbin Bw. A control unit 64 causes a traverse guide 72 to move between a predetermined position which and the traversal range r. The bunch guide 65 is structured to cause the yarn Y held thereby to be caught by the traverse guide 72 moving from the predetermined position into the traversal range r and to be detached from the bunch guide 65.
