Beating is performed by the
Is released. The pressing device 8 is returned in the direction opposite to the winding direction of the woven fabric W by one pitch (2 mm in this embodiment) with this opening operation.

After beating, the pressing device 8 clamps the woven fabric W at the returned position, lowers the upper vertical thread insertion member 10a slightly, and lowers the lower vertical thread insertion member 10b.
Rises slightly. At this time, the woven fabric W is
, The vertical thread Z is tightened. After that, the press device 8 is fed in the winding direction of the fabric W by one pitch in a state where the fabric W is sandwiched, whereby the fabric W is conveyed. The woven fabric W is wound up by the woven fabric winding device 5 in accordance with this transport operation.

Next, as shown in FIG. 8, the upper vertical thread insertion member 10a and the lower vertical thread insertion member 10b are retracted from the cloth fell position 6. One weft Y is inserted between the layers of the warp X, two wefts Y are respectively inserted outside the outermost layer of the bias yarn B1, and these three wefts Y
Is inserted between the layer of the vertical thread Z from the upper vertical thread insertion member 10a and the layer of the vertical thread Z from the lower vertical thread insertion member 10b. In this case, the weft Y inserted outside the outermost bias yarn B1 layer forms a surface yarn. At this time, the press device 8 is holding the woven fabric W at the above-mentioned sent position.

Thereafter, as shown in FIG. 9, the upper vertical thread insertion member 10a and the lower vertical thread insertion member 10b advance toward the cloth fell position 6, and these members 10a, 10b
The beating is performed, and at the same time, the press device 8 is opened. The pressing device 8 is returned in the direction opposite to the winding direction of the woven fabric W by one pitch with this opening operation.

After the beating, the pressing device 8 clamps the fabric W at the returned position, the upper vertical thread insertion member 10a is slightly raised, and the lower vertical thread insertion member 10b
Falls slightly. At this time, the woven fabric W is
, The vertical thread Z is tightened. Thereafter, the pressing device 8 is fed in the winding direction of the fabric W by one pitch in a state where the fabric W is sandwiched, whereby the fabric W is conveyed. The woven fabric W is taken up by the woven fabric take-up device 5 in response to this transport operation.

Thereafter, the upper vertical thread insertion member 10a is raised to the initial position (the position shown in FIG. 5), and the lower vertical thread insertion member 10b is also lowered to the initial position. Then, the weft Y is inserted between the layers of the warp X, and the above-described series of operations is repeated.

As described above, immediately after weaving, the vertical yarn Z is tightened after beating in a state where the woven fabric W is held by the press device 8, so that a three-dimensional woven fabric having a tight structure is woven. .

The three-dimensional loom according to the present invention further moves in the horizontal and vertical directions in conjunction with the operation of inserting the weft Y and the operation of the weaving shape holding device 7, and moves the weft Y to the front position toward the cloth fell position 6. An engaging rod is provided for engaging the weft engaging pin 19 at the position. 10 to 13 are plan views illustrating the operation of the engagement rod, the operation of inserting the weft Y, and the operation of the woven shape holding device 7. For clarity, the press device 8 and the vertical thread insertion members 10a and 10b are omitted in the figure.

10 to 13, the weft yarn Y is inserted by the weft rapier 25. First, as shown in FIG. 10, after the winding of the woven fabric W is performed, the weft Y is inserted by the weft rapier 25. At this time, the weft Y coming out of the pair of rollers 25a at the tip of the weft rapier 25 is
The weft rapier 25 is hung on the weft locking pin 19b at the forefront position toward the cloth fell position 6 on the insertion port side.

After the insertion of the weft Y, the first engagement rod 26 protrudes above the plane where the weft Y is located in a region between the weft rapier 25 and the weft Y emerging from the weft rapier 25. Then, as the weft rapier 25 retreats to the insertion opening, the first engagement rod 26 moves to the outside of the fabric W on the side opposite to the insertion opening, whereby the weft Y is moved to the first engagement rod. Multiplied by 26.

Thereafter, as shown in FIG. 11, the first engaging rod 26 is wound parallel to the fabric W outside the fabric W in the winding direction of the fabric W in a state where the weft Y is hung. It moves beyond the cloth fell position 6 and stops at a position substantially adjacent to the weft locking pin 19a at the foremost position toward the cloth fell position 6. As a result, the weft Y coming out of the first engagement rod 26 toward the fabric W comes into contact with the weft locking pin 19a. On the other hand, in the vicinity of the insertion opening of the weft rapier 25,
In a region adjacent to the weft Y extending from the weft rapier 25 to the first engagement rod 26, the second engagement rod 27
Project above the plane on which the weft Y is located.

At the same time, in the vicinity of the cloth fell position 6 on the first engagement rod 26 side, the next weft locking pin 1
9c protrudes above the transport surface. In this case, the weft locking pin 1
9c protrudes from the first engaging rod 26 between the weft Y extending toward the weft rapier 25 and the weft Y extending toward the woven fabric W. In this embodiment, the interval between the adjacent weft locking pins 19 in the winding direction of the woven fabric W is set to 2 mm.

Then, after the second engagement rod 27 moves to the outside of the woven fabric W on the side of the insertion opening of the weft rapier, as shown in FIG. It moves outside the cloth fell position 6 in the winding direction of the cloth W in parallel with the cloth W on the outside, and stops at a position almost adjacent to the weft locking pin 19b located at the foremost position toward the cloth fell position 6. I do. Thereby, the second engagement rod 2
The weft Y coming out of the fabric side from 7 comes into contact with the weft locking pin 19b. In parallel with the movement of the second engagement rod 27,
The beating by the vertical thread insertion members 10a and 10b is performed.

Next, in the vicinity of the cloth fell position 6 on the side of the second engagement rod 27, the next weft locking pin 19d protrudes above the transport surface. Thereafter, as shown in FIG. 13, the first and second engagement rods 26 and 27 are retracted downward from the transport surface and return to the initial position, and the weft Y is hooked on the weft locking pins 19c and 19d. . Then, the fabric W is 1
It is transported and wound up by the pitch (2 mm), the weft rapier 25 inserts the weft Y again, and the above-described series of operations is repeated.

As described above, since the weft Y is locked on the weft locking pins 19 arranged at equal intervals in the longitudinal direction at both side ear portions of the woven fabric W, the vertical yarn using the pressing device 8 is used. When the Z is tightened, the woven shape is kept constant without the fabric W shrinking in the width direction and the longitudinal direction.

That is, when viewed at the position of a certain weft Y, the folded back of the vertical yarn Z appears alternately up and down, so that the strength of the woven fabric is made uniform.

The weft Y serving as the surface yarn is a vertical yarn Z
Is arranged at a position where the intersection C of the bias yarns B1 and B2 does not exist at the position in the width direction where the insertion is performed, and the intersection C of the bias yarns B1 and B2 and the surface yarn Y alternate along the winding direction. Placed in The vertical yarn Z is a weft Y which is a surface yarn.
At the portion where the surface yarn Y does not exist, it is hooked and folded at the intersection C of the bias yarns B1 and B2.

FIG. 16 is a perspective view of a five-axis three-dimensional fabric woven by the three-dimensional loom according to the present invention.
