Both ends are stretched by hanging weights 12 in the state of being inserted into
Further, the vertical yarn Z ₁ and the vertical yarn Z ₂ are pulled out from the beam 11 and passed through the moving plates 17 and locked to the warp yarn Y.

The warp yarn Y ₁ , the warp yarn Y ₂ , the warp yarn Y ₃ , the warp yarn Y ₄ , the vertical yarn Z ₁ , and the vertical yarn Z ₂ are arranged side by side in the heddle frame 9 as shown in FIG. A set of six yarns are arranged side by side to form a yarn of a portion related to one heald device 2a.

The warp yarns Y ₁ , warp yarns Y ₂ , warp yarns Y ₃ , and warp yarns Y ₄ of each set are inserted through the insertion holes 21 of each moving plate 17, and each set of moving plates 17 is provided between the moving plates 17. It means that the vertical thread Z ₁ and the vertical thread Z ₂ of FIG.

Several sets of such six yarns are arranged for one heald device 2a. Therefore, as shown in FIG. 1, after all, several sets of six yarns are arranged in six parts so as to correspond to the respective heald devices 2b to 2f.

In the heddle device 2a, six heald frames 9 are arranged so that they can be moved up and down by a cylinder device 10, and the yarns arranged in the heald device 2a are a set of six as described above.
Several sets of (warp yarn Y ₁ , warp yarn Y ₂ , warp yarn Y ₃ , warp yarn Y ₄ , vertical yarn Z ₁ , vertical yarn Z ₂ ) are arranged. Therefore, 6
The innermost heald frame 9 among the heald frames 9 is locked with the vertical threads Z _{1 of} each set, and the second heald frame 9 is locked with the vertical threads Z _{2 of} each set. The heddle frame 9 is a warp thread Y _{1 for} each set.

Is drawn upward by the heddle frame 9 and the remaining thread is drawn downward to form the thread opening 3 (the number of thread openings 3 corresponds to the number of sets) (FIG. 2 shows vertical thread Z _1). Is pulled to the upper limit position and the other yarns are pulled to the lower limit position, that is,
During the process (1)), the shuttle 4 or the weft thread X passes through the plurality of thread openings 3 by being attracted by the magnetic force of the magnet 19 by the rotation of the rotary rod 13.

When the weft thread X passes through the thread opening 3, the reed 18
(In FIG. 8, warp yarn Y ₁ , warp yarn Y ₂ , warp yarn Y ₃ , warp yarn Y ₄ are located in the insertion hole 21 of each moving plate 17 in this order from the top, and the gap between the respective moving plates 17 is The vertical thread Z ₁ and the vertical thread Z ₂ are located in this order from the top.) The weft thread X that has moved through the center of the thread opening 3 and has passed through the thread opening 3 is pressed toward the center. This means that one organization has been woven. Subsequently, even in the heald device 2b located at the next position, the heald frame 9 operates in the same manner, and the shuttle 4 is guided by the rotation of the rotating rod 13, and similarly, in the heald devices 2c to 2f as well, the heald frames respectively. 9 works. Therefore, when all the heald frames 9 (for example, the first heald frame 9 in FIG. 6) at the same position of each heald device are activated, the weft yarn X has made one round.

Subsequently, the heald frame 9 at the same position (for example, the second heald frame 9 in FIG. 6) similarly operates from the heald device 2a to the heald device 2f, and when the shuttle 4 makes five turns, the shuttle 4 in FIG. (The vertical layer in FIG. 2) is woven, and by repeating this, the disk-shaped three-dimensional woven fabric 1 is woven while growing from the center to the outside.

FIG. 4 is an explanatory view of the weaving structure. For example, the movement of the heddle frame 9 of the heald device 2a when the # portion of FIG. 4 is woven is as follows.

The heddle frame 9 is moved to move the vertical thread Z ₁ from the fixed position to the upper limit position.

In this case, the other threads are pulled and moved from the fixed position to the lower limit position. The shed 3 formed by the rise of the vertical yarns Z ₁ and vertical yarns Z ₁ other than yarn drop inserting the weft X (X ₁ completed).

The disk is woven by repeating the above steps. The beating operation is performed after the disposition of each weft thread X is completed.

As described above, the yarns are woven by the raising and lowering of each heddle frame 9 and the movement of each reed 18.

The thickness of the disk to be woven is set depending on the number of warp threads Y in the vertical direction (the number of steps) (the outer diameter depends on the position where the weaving process is stopped). It will be fixed.).

When the shuttle 4 is mechanically moved around,
Although the device becomes complicated and the movement of the shuttle 4 is not smooth, the shuttle 4 according to the present embodiment moves circularly due to the magnetic force, so that the shuttle 4 can be moved very smoothly. As in the present embodiment, the shuttle guide plates 14 are arranged in parallel at intervals less than the length of the shuttle 4, and the shuttle 4 is moved by magnetic force. Since it does not come into contact with Y, it is possible to prevent the vertical yarn Z and the warp yarn Y from being damaged.

Further, the heald device according to the present embodiment is illustrated in a case where six heald devices are annularly arranged with a space L, but the number of heald devices is not limited to six. . Reed
The shuttle 4 must not be in the shuttle orbit when the reed 18 is operated in order to enable the movement of the shuttle 18. In order to secure an escape place for the shuttle 4, the shuttle track is not a continuous circular track, but at least two semicircular divided shuttle tracks are essential. Therefore, at least two heald devices are required.
