Abstract (en)

A device that achieves a reduction in the number of parts and reduces the space required by simplifying the arrangement of the rotating member that applies a twist to the yarn. A drive motor directly linked to a shaft is arranged on a pair of drive pulleys for applying a twist to a processing yarn. The drive motor is incorporated inside a holder that holds the drive pulley so that it may freely rotate.
