Abstract (en)

A traverse mechanism 4 of a yarn winding machine 1 includes a drive motor 53 which generates a rotation of a drive shaft 531, a crank disc 52 which converts the rotation of the drive shaft 531 of the drive motor 53 into a rotation of a circular orbit, and a reciprocating double slider crank portion 51 which converts the rotation of the circular orbit of the crank disc 52 into a reciprocating motion, the crank disc 52 includes a disc portion 521 which rotates while being connected to the drive shaft 531 and transmits power of the drive motor 53 and a crank pin 523 which transmits power to the reciprocating double slider crank portion 51, a distance between the disc portion 521 and the crank pin 523 is changeable, and the reciprocating double slider crank portion 51 includes a traverse guide 516 locking a yarn Y.
