As described above, the yarns are woven by raising and lowering each heddle frame 33 and moving each reed 48.

The thickness of the disk to be woven is set according to the number of vertical warp threads Y (the number of steps) (the outer diameter depends on the position where the weaving process is stopped). It will be fixed.). Next, a method for weaving a second doughnut-shaped three-dimensional fabric will be described (see FIGS. 12 to 17). This method is disclosed in Japanese Patent Application No. 5-43039 of the present inventor.

As shown in FIG. 13, the plate-shaped opening member 60 superposed in five steps is arranged in a regular octagonal shape.

This opening member 60, as shown in FIG.
The three-dimensional woven fabric 61 to be woven (hereinafter, this position is referred to as a reference position L) is composed of a lower support member 62 and an upper support member 63 that are moved up and down by appropriate means.
The opening member 60 is mounted on the mounting rod 62b of the vertical rod 62a of 62.

A through hole 64 is formed at a predetermined position of the opening member 60, and a through hole 65 is also formed at a position corresponding to the through hole 64 of the vertical rod 62a. Is the connecting pin 66
Has been penetrated.

The upper support member 63 is also the lower support member 62.
In the same structure as above, the vertical rod 63a of the upper support member 63 is located outside the vertical rod 62a. Reference numerals 67 and 68 are through holes, and 69 is a connecting pin.

Therefore, for example, when the uppermost one opening member 60 is raised and the remaining opening member 60 is lowered to form the opening 70 between them as shown in FIG. The connecting pin 66 is removed from the through hole 64 of the opening member 60 and the connecting pin 69 is removed from the through hole 67 of the opening member 60, and the through hole 68 of the vertical rod 63a of the upper support member 63 and the through hole 67 of the opening member 60 are removed.
When the connecting pin 69 is inserted into the uppermost opening member 60 and the uppermost opening member 60 is fixed to the vertical rod 63a, the upper support member 63 is raised and the lower support member 62 is lowered. An opening 70 will be formed between the opening member 60 and the remaining opening member 60.

Therefore, by inserting / removing the connecting pins 66, 69 and ascending / descending the lower support member 62 and the upper support member 63, an opening 70 can be formed between an arbitrary number of opening members 60 and the remaining opening members 60. It will be possible.

A pillar 71 is erected at the center of the opening member 60, and the warp yarn Y whose tip is fixed to the inner surface of the opening member 60 penetrates the pillar 71 and is opposed to the inner surface of the opening member 60. Is fastened to. Therefore, the warp yarns Y are arranged radially around the pillar 71. Reference numeral 72 is a spring as a tension device for applying an appropriate tension to the warp yarn Y.

An upper bar 74 and a lower bar 75, which serve as a vertical thread driving device 73, are provided above and below one side of the warp thread Y. The vertical thread Z is lifted and lowered by an appropriate means. In the figure, ◯ indicates the upper bar 74, and ● indicates the lower bar 75.), the vertical thread Z is derived from a bobbin (not shown), and the tip of the vertical thread Z is a warp thread near the support post 71. It is attached to Y.

Reference numeral 76 is a shuttle fixed to the tip of the weft thread X, and the base end of the weft thread X is fixed to the top of the support column 71.

Next, the operation of this apparatus, that is, the weaving process of the three-dimensional fabric 61 by this apparatus will be described with reference to FIG.

FIG. 12 shows that the warp yarn Y is made up of the warp yarns Y ₁ , Y ₂ ,
Y _3, Y _4, and 5 stages pair of Y _5, this 5-step set of warp yarns Y group is arranged radially Te strut 71 pungency and vertical yarns Z perpendicular yarns Z _1, 2 pieces of Z ₂ This is the case where one weft thread X is used.

The five opening members 60 are mounted on the mounting rod 62b of the lower support member 62, the lower support member 62 is lowered from the reference position L, and the upper rod body 74 and the lower rod body 75 are fixed at fixed positions. Leave.

In this state, when the shuttle 76 is manually moved around, the weft thread X comes to a predetermined position (X _{1 is} completed).

In the above state, the uppermost opening member 60 is raised from the reference position L, and the opening 70 formed by this is opened.
Then, the weft thread X that has made one round is passed (X _{2 is} completed). This state is the state shown in FIG. In the above state, the second opening member 60 is also lifted from the reference position L, and the weft thread X which has made one round is passed through the opening 70 thus formed (X ₃ completion). In the above state, the third opening member 60 is also raised from the reference position L, and the weft thread X which has made one round is passed through the opening 70 thus formed (X ₄ completion). In the above state, the fourth opening member 60 is also raised from the reference position L, and the weft thread X which has made one round is passed through the opening 70 formed thereby (X ₅ completion). In the above state, the fifth opening member 60 is also raised from the reference position L, and the weft yarn X which has made one round is passed through the opening 70 formed thereby (X _{6 is} completed). In the above condition, lower the upper rod 74 and lower the rod 75.
Raise.

This process is repeated, that is, the opening members 60 fixed to the vertical rods 63a of the upper support member 63 are sequentially lowered one by one, and the disc-shaped three-dimensional fabric 61 is supported by the columns 71 by repeating this process. It will be woven from the outside in order. Therefore, the disk-shaped three-dimensional woven fabric 61 can be woven very easily by using the device according to the present embodiment.
If the weft thread X is passed through the predetermined opening 70,
For example, it is good to beat using a board.

Three-dimensional fabric depending on the number of warp threads Y
The thickness of 61 is determined, and the outer diameter of the three-dimensional fabric 61 is determined by the position where the weaving process is stopped.

Although the opening member 60 is arranged in a regular octagonal shape in the drawing, the opening member 60 may be arranged in any shape such as a regular hexagonal shape, or may be arranged in an undivided annular shape.

The above weaving method of the three-dimensional woven fabric 61 is a type in which two vertical yarns Z are arranged for one warp yarn Y, but as shown in FIG. Against 1
A type of arranging two vertical threads Z (provided that adjacent vertical threads Z
The direction is opposite. ) Is also acceptable (FIG. 17 is a drawing corresponding to FIG. 13 in the case of one vertical thread Z).

When weaving the doughnut-shaped three-dimensional fabrics 31, 61 by the above two methods, the jig 3 shown in FIG. 18 is used.
To use.

This jig 3 is provided with a collar plate 4 having a diameter of acm on the upper and lower sides of the cylindrical body, and partition plates 5 are provided at equal intervals between the upper and lower collar plates 4 in the radial direction. The holes 6 are provided in a multi-stage manner, and the piano wire 7 is inserted through the holes 6 at the same position of each collar plate 4,
An annular piano wire 7 is arranged in multiple stages. The jig 3 can be disassembled and assembled by appropriate means.

The jig 3 is used as follows.

First, the case of using the first weaving method will be described (see FIG. 19). The jig 3 is fixed to an upper position (see FIG. 3) of the rotating shaft 40 by an appropriate means,
The piano wire 7 of the jig 3 is inserted through the ring portion formed at the tip of each warp yarn Y, and each warp yarn Y is stretched in the radial direction around the jig 3. In this state, weaving of the three-dimensional woven fabric A is started. The starting end of the vertical thread Z is simply hung downward, and when weaving proceeds, the starting end of the vertical thread Z is folded back in a state in which the weft thread X is wound, and the vertical thread is fixed with an appropriate adhesive or the like. An annular end portion 2 is formed at the starting end portion of Z (the weft yarn X passes through the annular end portion 2). Finally, when each piano wire 7 is cut and the jig 3 is disassembled and removed, the warp yarn Y and the starting end portion of the vertical yarn Z in the hole portion 1 formed in the central portion of the three-dimensional fabric A as shown in FIG. The doughnut-shaped three-dimensional fabric A having uniform strength is formed on the annular end portion 2 which is not the free end. Incidentally, it goes without saying that a ring portion may be formed at the tip of the vertical yarn Z in advance and the weft yarn X may be inserted through this ring portion. Next, the case of using the second weaving method will be described (see FIGS. 20, 21, and 22).

The jig 3 is fitted on the column 71 of FIG. 12, and each warp yarn Y is wound around the piano wire 7 of the jig 3 as shown in FIGS. Fasten to the rubber of.

[0076] Incidentally, FIG. 20 to 22 differs from the case described in the second weaving process, the warp yarns Y is 4 Y ₁ to Y ₄
The case of a book is illustrated.

Specific description will be made.

The warp yarns Y _{1 to} Y ₄ are loop yarns.

Two rubbers are arranged side by side in each opening member 60, and the warp yarn Y ₁ connected to the rubber on the front side in FIG. 20 of the uppermost opening member 60 is attached to the uppermost piano wire 7. To wind. Further, the warp thread Y ₁ continuously provided on the rubber on the back side in FIG. 20 is wound around the piano wire 7 which is the second from the top, and the opening member 60 which is the second from the top.
20 is continuous with the rubber on the back side in FIG. 20 and becomes warp yarn Y ₂ .

Hereinafter, as shown in FIGS. 20 to 22, each warp thread is stretched between each opening member 60 and each piano wire 7. In this state, the three-dimensional woven fabric A is woven by raising and lowering each opening member 60 as described above.

An annular end 2 is also formed at the starting end of the vertical yarn Z in the same manner as in the first weaving method.

When the three-dimensional woven fabric A is woven, the piano wires 7 are finally cut, and the jig 3 is disassembled and removed to form the central portion of the three-dimensional woven fabric as shown in FIG. The warp yarn Y and the vertical yarn Z in the hole portion 1 having a diameter of a cm are uniform doughnut-shaped three-dimensional fabrics A in which the starting ends of the warp yarn Y and the vertical yarn Z are formed in the annular end portion 2 which is not a free end.

FIG. 24 shows additional yarns Y _A1 , Y _A2 , Y _A3 , Y
Three-dimensional fabric B having an additional structure including _A4 , Z _A1 and Z _A2
(In either case of the first and second weaving methods, it is possible to weave by appropriately adding additional yarns Y _A and Z _A. This point is also disclosed in the prior application of the present inventor.) It is needless to say that the annular end portion 2 can be formed at the starting end portions of the warp yarn Y and the vertical yarn Z of the three-dimensional fabric B having such an additional design. Code C
Is the excised resection end in which additional tissue is woven, but it is possible to form the annular end 2 also in this portion instead of the resection end C. In this case, the weft yarn X already woven is used instead of the piano wire 7 of the jig 3.
