  • each traverse guide 14 attached to the slider 22 of the linear motor 20A turns around at one of the end portions of the traverse area in the traverse direction
  • each traverse guide 14 attached to the slider 22 of the linear motor 20B turns around at an opposite end portion of the traverse area in the traverse direction (for example, when each traverse guide 14 on the linear motor 20A turns around at a front end portion, each traverse guides 14 on the linear motor 20B turns around at a rear end portion). That is, the slider 22 of the linear motor 20A and the slider 22 of the linear motor 20B turn around at the same time to move in opposite directions with respect to the traverse direction.

  • the plurality of drivers 20 are aligned in a line in the traverse direction. In the above arrangement, it is possible to prevent a moment from being applied to the traverse unit 12 when the movable portions 22 turn around to move in opposite directions. Due to this, vibration occurring at the time of turnaround of the yarns Y is reduced more effectively.
  • each of the drivers is the linear motor 20, and the movable portion is the slider 22 of the linear motor 20.
  • a traverse unit in which traverse guides are attached to a belt, which is an elastic member.

  • the traversal speed at which the yarns Y are traversed is 8 m/min or higher.
  • vibration at the time of turnaround of the movable portions 22 tends to be large, and therefore the present invention is particularly effective.
