  • a jig (not shown) that grips the upper part of the ring 3 is rotated in one direction, while both holders 711, 712 are rotated in the other direction. Then, the welded portion 30a and the cut portion 30b of the base portion 30 of the ring 3 are brought into close contact with the welded portion 31c and the cut portion 31d of the ring body 31. Subsequent processing is the same as in the first embodiment.
  • each of the multiple ring bodies 31 can be positioned and inserted into the binding hole 21a while maintaining that position. Therefore, each ring body 31 can be accurately inserted into and passed through the binding hole 21a.
  • both holders 711, 712 pass through the binding hole 21a together with the ring body 31 while gripping the ring body 31. This allows the ring body 31 to pass through the binding hole 21a with high precision and reliability.

  • This ring threading device 14 uses a ring 8 as shown in FIG. 13. That is, the ring 8 has a base portion 80 and a ring body 81. A protrusion 81a that protrudes from the surface by a predetermined thickness is integrally formed at the tip of the ring body 81. The lower end of the protrusion 81a has a tapered shape like the tip of the ring body 81. In addition, the upper end of the protrusion 81a has a tapered shape that tapers upward.
  • the positioning jig 76 is disposed above the mounting table 75, i.e., on the same side of the mounting table 75 as the side on which the ring 8 is disposed, and can be raised and lowered freely.

Both longitudinal ends of the connecting portion 762 are supported by the support member 763 so that it cannot move up and down, but can move freely in the horizontal direction.
  • the backplate 77 is positioned opposite the positioning jig 76. In other words, the backplate 77 is positioned so that it comes into contact with the surface of the ring body 81 opposite the surface that comes into contact with the positioning jig 86. This backplate 77 stabilizes the position of the ring 8 as it descends.
  • the jig moving mechanism 78 has a hydraulic cylinder or the like. This jig moving mechanism 78 makes it possible to move the positioning jig 76 closer to and away from the back plate 77.

  • the positioning jig 76 is moved close to the back plate 77 by the jig moving mechanism 78. As a result, the ring body 81 of the ring 8 is sandwiched between the back plate 77 and the positioning jig 76. Next, the positioning jig 76 is lowered by the ring moving mechanism 79. As a result, the recess 761a of the positioning portion 761 engages with the protrusion 81a of the ring body 81. In this state, the positional relationship between the two is fixed by the recess 761a of the positioning portion 761 and the protrusion 81a of the ring body 81, and the adjacent ring bodies 81 are positioned while maintaining the interval between them. Then, when the positioning jig 76 and the ring 8 are lowered from this state, the positioning portion 761 of the positioning jig 76 and the ring body 81 pass through the binding hole 21a.
