DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The front and back different woven fabric according to the present invention is based on plain weaving a warp made of differently laid ribbons and placing one of the warps and a weft consisting of the same pattern ribbon. The warp on both sides is woven with a single ribbon similar to the weft. Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

FIG. 1 shows a front side (a), a back side (b) and a side cross section (c) of a front and back different fabric according to the present invention.

The front and back patterned fabric 1 in the present embodiment is
The black and white two types of ribbons 2 and 3 are flatly stacked to form a warp 4, and the weft 5 may have any pattern. In this example, the black and white ribbons 3 and 6 are the same type. Make up.

According to the weaving of the warp yarns 4 and the weft yarns 5, a pattern of black and white spots is formed in Table 7 of the front and back differently woven fabric 1 as shown in FIG. The back 8 of the front and back differently woven fabric 1 forms a black color pattern.

[0016] Then, the different pattern can be easily brought out on the front and back surfaces. For example, when the front and back differently woven fabrics 1 are formed as shawls, the front and back differently woven fabrics 1 are turned to the front and back in a difficult place. By using the back 8 of the differently woven fabric 1 as a lining, it is possible to produce radiance while exhibiting moderate thickness adjustment.

On the other hand, in a case such as participation in a funeral process, the back 8 of the front and back differently woven fabric 1 is made to be a surface, so that the atmosphere of Kyojun can be sufficiently created. It is easy to use them properly.

As described above, the front and back fabrics according to the present invention are constructed by arbitrarily selecting the pattern of the flatly stacked ribbon constituting the warp and the pattern of the ribbon constituting the weft. The fabric can be easily woven while selecting various combination patterns according to the way of using the fabric, the place of use, and the like.

In this embodiment, as shown in FIG. 2, the edge 9 of the front and back patterned fabric 1 is woven with the weft 5 made of the black ribbon while the warp 4 is formed as one layer of the black ribbon 3. As a result, the pattern of the rim that is easily visible as a woven fabric is unified to black, and the quality of the woven fabric such as a shawl is enhanced by tightening the rim pattern strictly. At this time, a single warp 4 and a weft 5 of the same pattern
Are woven a plurality of times, whereby the edges of the real and reverse patterned woven fabrics can be configured more reliably.

As described above, the two-sided and woven fabric according to the present invention employs a ribbon as a material, and at the same time, forms a double structure of ribbons having different patterns and weaves it with a weft of an arbitrary pattern. By being able to weave a variety of different patterns on the front and back while being a woven fabric, it is possible to use the woven fabric with different patterns depending on the application, expanding the usability over a wide variety of fabrics I have.

In order to form the above-mentioned two-sided and differently-woven fabric, the overlapping weaving method and the two-layer loom of the two-sided and differently-woven fabric according to the present invention are arranged such that warps in which differently-shaped ribbons are flatly stacked are cut into shreds.
The differently laid ribbons of the warp laid flat are separately passed through the heald and alternately moved up and down, while the plate shed that arranges the ribbon of an arbitrary pattern as the weft is alternately intersected between the differently laid ribbons that move up and down. It is configured to perform plain weaving while regulating the arrangement of the warp and weft, and then wind up the woven fabric plain woven in a different pattern on the front and back into 1000 windings.

Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings. This embodiment shows a schematic configuration of a lapping loom in a case where the present invention is applied to a spinning loom. The basic configuration will be shown in a perspective view, and the main part of the invention will be described in detail with reference to the partial views.

FIG. 3 is a perspective view of the lapping loom according to the present invention, in which only main parts are emphasized so that the configuration of the present invention can be easily understood.

The lapping loom 10 in the present embodiment is basically composed of a shredder 11, a heald 12, a reed 13 and a thousand winding 14. The heald frame 15 of the heald 12 is operated by a treadle 16 and By manipulating the frame 17, a warp 4 in which different-shaped ribbons are flatly stacked and a weft 5 composed of an arbitrary-shaped ribbon are provided.
And plain weave.

FIG. 4 shows the differently shaped ribbons 2 laid flat.
After the warp 4 composed of 3 and the weft 5 composed of a ribbon of an arbitrary pattern are arranged in the shredded section 11 and laid flat via a twill bar, a heald, a reed and the like, and then plain-woven, the FIG. 4 is a side view schematically showing a series of steps of winding on a winding 14.

The ribbons 2 and 3 of different shapes after warping to a predetermined length are individually arranged in the shreds 11. The warp yarn 4 passing through the twill bar 18 is set in a state where the different ribbons 2 and 3 are flatly stacked. When the respective ribbons 2 and 3 reach the heald frame 19, they are individually passed through the heald 15. You.

The healds 15 are constructed in various combinations, so that the ribbons 2 and 3 can be peeled off from each other, or the ribbons 2 and 3 move up and down together while being adjacent to each other. It is possible to arbitrarily select to form a set like the ribbons 2 and 3 together moving up and down in the direction.

The ribbons 2 and 3 that have passed through the heald frame 19 are
They are combined again in a state where they are laid flat, and then inserted as warps 4 into the reeds of the reed frame 20 in order. Therefore,
After passing through the reed frame 20, the warp yarns 4 are alternately sorted in the vertical direction to form a gap 22 between the warp yarns 4 in which the board shed 21 equipped with the weft yarns 5 can be transferred.

By the above-mentioned vertical movement by the heald frame 19,
The weft yarns 5 are woven between the warp yarns 4 by the operation of exchanging the warp yarns 4 in the vertical direction for each sorting, and the transfer operation of reciprocating the plate shed 21 equipped with the weft yarns 5 to follow.

The reed frame 20 completes a plain weave of the warp 4 laid flat and the weft 5 made of a ribbon of an arbitrary pattern by a subsequent pulling operation. Has been taken into. In the following,
The function of each part will be described in detail.

In this embodiment, as shown in FIG. 5, two rods 23, 2, which are arranged with a step before attaching the warped different ribbons 2, 3 to the shredder 11.
It is routed in a state of being separated into 3 '.

Two rods 23 attached to the shredder 11,
The mounting means 23 'can be provided by various methods. In the present embodiment, the mounting means 23' are individually arranged by passing through the woven cloth 24 fixed to the shredder 11, respectively. Is provided with a tension adjusting mechanism for adjusting the length and slack of the warp yarn 4 by moving the position of the woven fabric 24.

The difference in the slack of each ribbon due to the difference in the winding radius of the shred 11 caused by the thickness of the strip 11 can be appropriately corrected.

The heald shown in FIG. 6 shows an example suitable for layering the differently woven fabric according to the present invention, and is different from a normal heald.

As described above, for the warp, a plurality of heald frames constituting a combination group of healds are arranged while a single warp is individually inserted into the plurality of healds provided on the heald frame.
The vertical movement of each heald frame is controlled by the operation of the crossing. In the present embodiment, a plurality of healds, each of which is a set of four healds, are operated simultaneously by the heald frame.

That is, the four healds are used to separate the differently shaped ribbons (2, 3) and (2, 3) constituting the two sets of warp yarns 4, 4 into individual healds 26-1 to 26-4. Through each of the insertion holes,
In order to keep the healds 26-1 to 26-4 separated from each other, the heald groups 26-1 and 26-3 and the heald groups 26-2,
Heald frame 27 for placing the two groups 26-4 in a vertical relationship with each other
(26-1, 26-3) and 27 '(26-2, 26-
4) and the heald groups 26-1, 26-2 and the heald groups 26-3,
Heald frames 28 (26-1, 26-2) and 28 '(26
-3, 26-4).

The front and back different-woven fabrics according to the present invention are plain weaves of warp and single weft consisting of ribbons of different patterns which are laid flat, but by operating the heald frames 27 and 27 'as described above. Separating the superimposed ribbons appropriately is an effective function to prevent the flat superimposed ribbons from twisting together and leading to an undefined front and back, making it possible to precisely separate the front and back fabrics with precision. It is an effective means for weaving.

On the other hand, operating the heald frames 28 and 28 'forms a gap 22 between the two sets of warp yarns 4, 4 for transferring the plate shed 21 equipped with the weft yarns 5, and the warp yarns 4 and the weft yarns 4. 5
This is the usual operation of weaving.

The heald shown in FIG. 7 shows another example suitable for layering the front and back fabrics according to the present invention. The configuration of the heald group in the heald frame is the same as that of the embodiment shown in FIG. Is the same as

As shown in the figure, the healds 29-1 to 29-4 in the present embodiment are formed with insertion holes 30 parallel to the warp yarns 4 made of differently laid ribbons. -1 to 29-4, the operation of inserting the ribbons 2 and 3 and the operation of the heald frame to separate and overlap the warp 4 can be performed smoothly by reducing the twist of the warp and each ribbon. it can.

The reed shown in FIGS. 8 and 9 is constructed in a state associated with the above-mentioned heald so that the desired front and back differently woven fabrics can be woven while controlling the arrangement of the warp and the weft. Are located.

In the embodiment shown in FIG. 8, each ribbon 2,
3 are passed through each reed 31 in a state of being overlapped again, and when the ribbons 2 and 3 are placed at separated positions as shown in the figure, or depending on the group of healds, the warp 4 is integrated into each reed 31. May be inserted.

However, the separation state of the ribbons 2 and 3 is merely for the purpose of eliminating the twist and the like of the warp piled up flat, and the warp after passing through the reed 31 makes the ribbon of different pattern flat. It is regulated so that it is arranged in parallel in a stacked state,
It will be plain woven with the weft.

Another embodiment of the reed shown in FIG.
This is a special reed 32 for overlapping and weaving front and back different woven fabrics according to the present invention corresponding to the heald described in FIG. 7, and the interval between each reed is set to the width of the ribbon configured as a warp. As a result, the arrangement of the warp yarns and the regulation of the fabric with different patterns on both sides are made more accurate.

In this embodiment, even a reed exclusively for front and back fabrics in which different ribbons are laid flat and woven,
The interval can be appropriately set by adjusting the attachment relation to the reed frame.

The warp yarn 4 after passing through the reed frame 20 is operated by the above-mentioned vertical movement by the heald frame 19 so that the warp yarns 4 are exchanged in the vertical direction each time they are sorted, so as to follow this. By reciprocating the board shuttle 21 equipped with the weft 5, the weft 5 is woven between the warps 4, and the plan view (a) and the side view (b) of FIG. This shows the last progress of the weaving of the patterned fabric.

That is, the warp yarns 4 composed of flat ribbons of different patterns are sorted so as to move alternately in the vertical direction, and the gaps 22 formed between adjacent warp yarns 4 are formed. By moving the board shuttle 21 back and forth, the weft 5 and the warp 4 mounted on the board shuttle 21 are plainly woven, so that the front and back fabric 1 is woven.

In ordinary plain weaving, the reed stile 20 is drawn after the board shuttle 21 is reciprocated, so that the warp 4 and the weft 5
However, in the present embodiment, FIG.
As shown in the plan view (a) of FIG. 0, the warp 4 and the weft 5 are suppressed by using an empty board shuttle 33 in place of the reed stile 20. By applying a pressing force to the ribbon or the ribbon constituting the weft yarn 5 while taking into account its parallel characteristics, the quality of the woven fabric with different patterns is strictly regulated.

[0049] While the woven front and back woven fabric 1 is wound up by the 1000 rolls 14, the plain weaving of the subsequent front and back woven fabric 1 is continued, but as described above, the flat woven fabric 1 is laid flat in the weaving process. Between the ribbons of the warp or between the warps arranged in parallel, the difference in the feeding length based on the thickness of each ribbon when wound on the shredder 11, the difference in the elongation of the material, and the rod passing from the shredder 11 Due to the difference in tension and the difference in slack caused by the bending of the twill bar and the like, it is necessary to consider the difference in strain and tension between the front and back differently woven fabrics as the weaving stage is approached.

For this purpose, in the present embodiment, a clamping device 25 for adjusting the length and slack of the warp 4 as shown in FIG.
It has.

When the tension adjusting mechanism described above comes to a state in which the two rods 23 and 23 ′ which are arranged with a step on the shredder 11 at the end of weaving are visible, for example, one of the ribbons 2 passes therethrough. By changing the position of the rod 23, it is possible to appropriately correct the difference in the slack of each ribbon caused by the thickness of the ribbon, the bending of the rod, and the like. The quality of the fabric is ensured.

Since the weaving method and the weaving loom for the front and back different fabrics according to the present invention are configured as described above, the woven front and back different fabrics are prevented from being distorted or flattened into barrels. By improving the weaving efficiency by ensuring the quality and omitting the parts and simplifying the operation, it is possible to simply and surely weave fabrics having different patterns on the front and back.

As described above, the present invention has been described in detail based on the embodiments. However, the front and back different woven fabrics and the overlapping weaving method and the overlapping loom according to the present invention are not limited to the above embodiments. Since the present invention can be applied to other looms such as a combination of warp and weft patterns, rod mounting means, and other types of looms or portable table looms, the spirit of the present invention is deviated. It goes without saying that various changes are possible within a range not to be performed.
