Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a method and device for adjusting the weave width of textiles, as well as a completely new fan-shaped reed that is directly used in carrying out the method. It is characterized by adjusting the weaving width by changing the arrangement density of warp yarns by appropriately moving up and down a novel fan-shaped reed, which has a denser upper or lower part and a coarser one on the opposite side.

[Prior art]

Kasori-sewn bag obi is made by weaving the outer material and the lining separately, then stacking the two fabrics with the back sides inside and sewing the edges together to create a cylindrical shape. Therefore, there is no need to turn it inside out after sewing, and since there is no sewn-in part, the edge ends are not bulky and can be finished smoothly and beautifully.

However, in the case of sewn fabrics, depending on the coarseness, size, position, and fineness of the threads, the warp threads of the patterned part [phase] are gathered together as shown in Figure 6, and the cloth changes greatly. When making this into a kasori-style fukuro obi, it was extremely difficult to weave the fabric so that the widths of the front and back sides were the same.

For this reason, based on the narrowest part of the weaving width, in areas that can be woven wider than that, the warp threads at the selvedge @ are forcibly pulled up or pulled down to avoid weaving some of the warp threads. valid .

The weaving width is adjusted by increasing or decreasing the number of warp threads.

This method is extremely complicated; the loom must be stopped as the weaving width changes in each part of the weave, and it takes time to dispose of excess warp threads. This has led to a significant decline in visual acuity and product aesthetics.

In contrast, the applicant had previously applied for a method for adjusting the weave width by pulling up and regulating the desired amount of warp threads in the selvedge portion of the fabric through the threads in accordance with the signal from the jacquard (Japanese Patent Application No. 1987- No. 88140, filed on April 24, 1980), however, as a final Fi finishing for the fabric woven by this method, the labor-intensive work of cutting off the warp yarns left loose at the edges due to pulling up is required. did.

[Problem that the invention seeks to solve]

In order to make the width of the sewn fabric uniform, the present invention uses the designed number of threads without increasing or decreasing the number of warp threads, and knits the material into a characteristic fan shape! , by sliding the 11 up and down at any time to change the actual density of the material at the reed beating part, and by selecting the required chain, the desired width can be obtained freely. be.

[Failure to solve the problem]

The present invention involves attaching a completely new fan-shaped reed described below to a loom, passing all the warp threads during the weaving process, and changing the arrangement density of the warp threads by sliding the reed up and down as appropriate. This is to adjust the width.

〔Example〕

Figures 1 to 8 show the state in which the reed according to the present invention is attached to the weaving gate. It was formed by implanting what is called a fan-like structure, with the upper left and right sides being the wealth and the lower part being the base. The difference in density between the top and bottom of the moxibustion object is designed by the density and size of the pattern formed on the moxibustion object and the amount of vertical movement of the reed.

As shown in the above-mentioned drawing of the reed according to the present invention, the loom is provided with a vertical sliding groove (7) fixed to the inside of the left and right upper stile mounting parts (■■) via mounting plates (■■). The guide column (8) is provided via a sliding plate (8) so as to be able to slide vertically along both sliding grooves.

The reed ■ is naturally fitted into the reed support frame ■, but this reed support frame ■ and the sliding plate ■■ are rotatably supported by pins [phase] [phase], and both slide The space between the boards is rotatably supported by a single cross member @ with a shaft 00,
The left and right sides of the passing material ■ can be moved up and down individually by adjusting the thumb screw ◎ [phase] with left and right pressure.

In the above reed (2) according to the present invention, the density of the construction (2) may be upside down, and the bottle [phase] [phase] of the reed receiving frame (■) may be used instead of a thumbscrew as the operation means for vertical movement of the reed. The reed may be moved up and down by connecting a rod 0 to and moving this rod up and down by appropriate means as necessary. Furthermore, if the structure is such that the reed support frame ■ can be directly moved up and down, the annual support frame ■ and the sliding plate ■ are integrated, and the outer surface of the sliding plate is formed into an arc shape to invite the finger r II J count ■. It may also be fitted into a movable part.

[For production]

In the present invention, as shown in Fig. 4, the warp [phase] is passed through the middle position of the rib-like n wings, and if the left side edge of the fabric becomes narrow, loosen the thumbscrew 0 by turning it counterclockwise. When the reed is lowered as shown by the two-dot chain line, the upper part of the reed is lowered, the warp threads of the selvage are brought to the center, and the weaving width on the left side is narrowed. This “7”
With F yarn, not only the selvedges are moved toward the center, but the warp threads on the left half are all moved toward the center one after another, and because they are not locally dense, distortions in the texture of the fabric cannot be seen with the naked eye. Become.

Contrary to the above, if you want to make the left ear wider, tighten the thumbscrew and raise the reed, and the thick part will be located between the warp threads and the warp threads will be 1. :4 The enlightenment is expanded.

On the other hand, if you want to narrow the V+8 width by moving the left and right ears inward at the same time, lower the reed in parallel as shown in Figure 5, and the warp will be located in the dense part of the warp. Therefore, the weave width is narrowed over the entire width. Conversely, if the reed is raised in parallel, the weaving width will be expanded by the same fg and principle.

Therefore, if the left side of the reed is lowered and the right side is raised, the warp threads will naturally become denser in the left half of the fabric and coarser in the right half, and when viewed from the center warp, the left half will be caught and the right half will be An expanded fabric is obtained.

By performing the above operations in combination as appropriate depending on the size and shape of the pattern part of the fabric, the edges of the fabric other than the pattern area can be narrowed, or the edges of the first part of the pattern can be expanded to straighten the edge lines of the fabric. , a parallel width fabric can be obtained.

〔Effect of the invention〕

As described above, the present invention takes into consideration the shrinkage margin in the width direction of the part according to the size and position of the reed, and moves the left and right sides of the reed, which is implanted in a m-tubular shape as a whole, up and down as appropriate. By adjusting the n width, the weave width of the unpatterned part and the rk width of the patterned part can be made equal, and the ear ring can be made straight.

Therefore, since the warp threads do not float at the selvage part as in the conventional case, there is no need to cut out that part, and it is possible to obtain an i-cut fabric with a beautiful selvage part finish.

Therefore, by stacking the two sashes woven using the above method with the back sides inside and oversewing the selvage 1R7i, a straight selvage belt with a straight selvage part can be obtained without having to turn the selvage inside out after sewing. .

Also, is the present invention ff? i, QS- and cheaply D! It can be used for 11 productions and is very easy to work with.It has high industrial applicability.
