Attached. The distal end of the first arm 14 has a guide hole 16 through which the linear body 2 is inserted.
Is provided.

As shown in FIG. 1, the position of the guide hole 16 from the center of rotation of the spin body 6 is the same as the surface of the winding layer of the linear body 2 wound on the carrier 1, or the diameter is larger than that. It is desirable to be arranged at a position outside the direction. Guide hole 16
In order to prevent the linear body 2 from being worn, a material having high wear resistance or a material having low contact resistance, such as a ceramic die, a cemented carbide tip, or a diamond die, may be provided on the inner peripheral surface.

A second arm 17 is provided on the spin body 6 at a position 90 degrees upstream of the first arm 14 in the winding direction of the linear body 2. The second arm 17 includes a radial portion 18 extending radially outward from the spin body 6, and an axial direction bent 90 degrees from the tip of the radial portion toward the linear body 2 wound around the carrier 1. It comprises a portion 19 and a fall-off prevention portion 20 which is bent 90 degrees outward from the lower end of the axial portion 19.

As shown in FIG. 2, the axial section 19 is separated from the winding layer 2a of the linear body 2 wound around the carrier 1 by a predetermined distance. The falling-off preventing portion 20 prevents the linear body 2 passed outside the axial portion 19 from falling off. In the present embodiment, the mounting angle of the second arm 17 is set to 90 degrees on the upstream side in the winding direction of the linear body 2 with respect to the first arm 14, but is not limited thereto. However, about 30 to 120 degrees is preferable.

The spin body 6 is provided with a similar sub second arm 17a located on the opposite side of the second arm 17. The sub second arm 17a includes a radial portion 18a, an axial portion 19a, and a fall prevention portion 20a. When the winding direction of the linear body 2 wound around the carrier 1 is opposite to that of the present embodiment. Is used instead of the second arm 17 and serves as a balance weight for the second arm 17 to realize stable rotation of the spin body.

The spin body 6 is provided with a third arm 21 extending upward. The third arm 21
The tip is bent toward the rotation center of the spin body 6,
A guide hole 22 through which the linear body 2 is inserted is provided at the tip. The guide hole 22 is located substantially on the center axis of rotation of the spin body 6.

The third arm 21 may be attached to the spin body 6 so as to be rotatable about its axis, similarly to the first arm 14. In order to prevent the linear body from being worn, a material having high wear resistance or a material having low contact resistance, such as a ceramic die, a cemented carbide tip, or a diamond die, may be provided on the inner peripheral surface of the guide hole 22.

The operation of the present embodiment having the above configuration will be described.

As shown in FIGS. 1 and 2, the end of the linear body 2 wound around the carrier 1 is passed through the outside of the axial portion 19 of the second arm 17 to guide the first arm 14. After being inserted into the hole 16 and inserted into the guide hole 22 of the third arm 21, it is drawn upward in the axial direction. As a result, the linear body 2 wound around the carrier 1 is released from the winding layer 2a and drawn upward.

At this time, the linear body 2 is formed by the winding layer 2 of the carrier 1.
