Abstract (en)

To provide a yarn winding machine 1 including a traverse device 21, a contact roller 31, a turret plate, a yarn removing device, and restriction guides 75. The turret plate changes positions of the first bobbin holder 41 and the second bobbin holder 42 during a bobbin switching time. During the bobbin switching time, the yarn removing device removes the yarn wound on a first bobbin 91 from the traverse device 21. The restriction guides 75 are each provided so as to correspond to both sides of a yarn layer region of the first bobbin 91, and before completing an operation of removing, by the yarn removing device, the yarn from the traverse device 21, restricts the yarn wound on the first bobbin 91 to within the yarn layer region of the first bobbin 91 in an axial direction of a package 94.
