2. Description of the Related Art It is well known in the field of lap stitches such as appliqués to sew a cloth having a bent cutting line to the other cloth to be a base along the cutting line.
However, when two pieces of cloth are sewn together, not only a step corresponding to the thickness of the cloth is formed in the stitched portion, but also the iron is caught on the step during ironing and the step is not performed smoothly. In addition to the above, there is a problem that the iron is strongly hit only on the step and the press mark is left on the step. As a means for eliminating the stepped portion of such a stitched portion, as shown in FIG. 12, two pieces of cloth pq are cut into a curve having a fitting pattern such as concave and convex, and two pieces are cut. It is conceivable to sew along the cutting line in a state where the front side of the cloth pq is sewn facing the front side, and then the surface of the cloth pq is divided into right and left.

According to this method, the steps are eliminated because the fabrics p and q do not overlap when divided, but in the fabric p and q, one of the seams is a concave curve, but the other is a convex curve, and therefore the two are different. , It is extremely difficult to sew while sewing the position, and when the sewn fabric p.q is broken, the seam portion becomes tight or slack, and the fabric is wrinkled, so that it cannot be easily and beautifully finished. The present invention solves the above-mentioned conventional problems, in which two cloths are sewn with a curved line as a boundary without a step, and the cloth is not kinked or wrinkled at the sewn point, and An object of the present invention is to provide a sewing method capable of surely suturing.

[0004]

In order to solve the above problems, the present invention takes the following measures. That is, in the method for sewing a sewn product according to claim 1, the end portion of one cloth A is folded back by a predetermined width to form a fold line a along an arbitrary curve, and the cloth A is woven on the other cloth B. After sewn the fabrics A and B together by sewn the fabrics A and B near the folding line a in the vicinity of the folding line a with a seam m along the curved shape, the fabric B and the fabric B at the portion overlapping the fabric A are It is characterized in that the cloth A is folded back along the seam m so that the cloth A and the cloth B are aligned on the same surface.

The method of stitching a sewn article according to a second aspect is characterized in that, in the above-mentioned means, when the folding line a is formed, the overlapping portion of the folding portion is bonded with an adhesive. The sewing method according to claim 3 is characterized in that, in any one of the above-mentioned means, the folding line a of the fabric A is fitted into the folding line b of the fabric B by slackening and is aligned on the same plane. To do. The sewing method for sewing a sewn product according to claim 4, wherein in any one of the above sewing methods for a sewn product, a cloth C is applied to the backs of the cloths A and B arranged in the same plane, and the cloth C is placed on the seam m. And the cloth C at the same width position from the folding line a on the other cloth B,
It is characterized in that it is possible to prevent the product from losing its shape due to the stretch of the cloth by sewing each of them and forming substantially parallel seams n and r.

According to a fifth aspect of the present invention, in the sewing method of the fourth aspect, the first sewing thread is withdrawn after the parallel stitches n and r are formed.
According to a sixth aspect of the present invention, in the method of suturing a sewn article according to the fourth aspect, an adhesive is interposed when the cloth C is applied to the backs of the cloths A and B. According to a seventh aspect of the present invention, in the method of the sixth aspect, the first sewing thread is extracted before forming the parallel stitches n and r. According to an eighth aspect of the present invention, in the method of suturing a sewn article according to the sixth aspect, the adhesive uses rubber glue for the cloth and konjac glue for the cloth.

As described above, according to the stitching method of the present invention, the seam m for stitching the fabrics A and B is along the fold lines a and b in both the fabric A and the fabric B. The folded lines are lined up next to each other with no gaps along the same plane, eliminating the overlap of the fabrics, and since there is no need to split the two fabrics after stitching, there are no kinks or wrinkles in the fabrics. The fabrics A and B are sewn together along two curved seams n and r. In addition, by being joined to the cloth C, it is reinforced as compared with the state where it is sewn only by the seam m. Further, first, by removing the seam m that sewn the fabrics A and B and leaving only the seams n and r, the state becomes closer to a single fabric and the step portion of the fabric is eliminated.

DETAILED DESCRIPTION OF THE INVENTION

First Embodiment Next, a first embodiment of the present invention will be described with reference to the drawings. 1 is a plan view showing a finished product of a fabric sewn according to Example 1 of the method of the present invention, FIG. 2 is a perspective view showing the first stage of Example 1, FIG. 3 is the same second stage, and FIG. 4 is the same. Third stage, Figure 5
Is a perspective view showing the fourth stage, FIG. 6 is a perspective view showing the fifth stage, FIG. 7 is a rear view showing the sixth stage, FIG. 8 is a perspective view showing the seventh stage, and FIG. 9 is the eighth stage. It is a side view which shows.
AB is a cloth to be sewn like a suit cloth. First, one cloth A is cut along a predetermined curve (first step, FIG. 2), and a certain cutting line 1 is used. The end portion of the fabric A is folded back to its back side along a folding line a parallel to the cutting line 1 by a length (for example, 7 mm) (second step, FIG. 3). In this case, the cloth A is turned over, and the pattern 2 having the same shape as the cutting line 1 is applied to the cloth A, and the cloth A is folded along the peripheral edge of the pattern 2 and ironed from above. a is efficiently produced. In addition to this, if the folded-back portions are glued together, it is possible to prevent the occurrence of misalignment during stitching.

Next, the cloth A is laid on the cloth B with the folded-back portion facing downward, and the inside of the folded-back line a of about 1 to 2 mm is loosened along the folded-back line a and sewn with a sewing machine to fabric A.・ Connect B (3rd step, Fig. 4).
The position of the seam m of this sewing machine depends on the material of the cloth, and it is necessary to sew deeper than the folding line a in the case where the hair is long and easily frayed, but it is desirable to be as close to the folding line a as possible. After connecting the fabrics A and B in this way, the fabric A is cut off with scissors leaving a width substantially the same as the folded portion of the fabric A in the portion overlapping the fabric A (fourth step, FIG. 5), and the cut ends thereof. Is further folded back to the back side of the fabric B along the seam m (fifth step, FIG. 6). In this case, turn over the fabrics A and B, fold back the end of the fabric B while ironing along the seam m, and insert the notch 3 with scissors at the fold portion corresponding to the outer circumference of the curve, The edges of fabric B can be folded back (sixth step, Fig. 7). Needless to say, the end portion of the fabric B may be cut along the planned seam m before sewing.

When the end of the cloth B is folded back, the cloth A is finally
・ Lightly pull B in the opposite direction to loosen the seam m, and
The folded back line a is pushed into the folded back line b of the fabric B so that the folded back line a and the folded back line a and b are aligned side by side in the same line without a gap (seventh step, FIG. 8). In this case, if the iron is applied to the seam m and pressed, the fold lines a and b
Are easily aligned on the same plane. When the fabrics A and B are curved, the folding lines a and b naturally follow the same curve.

Thereafter, a cloth C having a constant width is applied to the back surfaces of the joined cloths A and B, and stitches are made on the seam m and along the folding line b on the cloth B to form seams n and r (eighth). Steps (Fig. 9). In addition, when applying the cloth C, an adhesive material, for example, konjac paste may be interposed. By the stitching, the seam n overlaps the seam m and is located outside the fold line b by about 1 to 2 mm. Here, the distance from the folding line a to the stitch n and the distance from the folding line b to the stitch r are substantially equal. The present embodiment can realize a curved sewn product in a good sewn state with the above configuration.

[0012]

Second Embodiment This second embodiment relates to an improvement of the first embodiment, in which the cloth C having a constant width in the eighth step of the first embodiment is applied to the back surfaces of the cloths A and B through an adhesive, After joining, the sewing thread of the seam m is pulled out, and then the fabric C is joined to the joined fabrics A and B on the seam m (however, there is no sewing thread) and along the fold line b on the fabric B. Suture (FIG. 10). According to this Example 2,
Since the first sewing thread does not exist, the two parallel threads are the same, which is preferable in terms of design. In the second embodiment, the seam m was extracted before the seams n and r were provided. However, by removing the seam n and r after the seam n and r are formed, the shape of the sewn portion can be made more reliable. . In the above examples, the sewn product is expressed as a cloth, but it goes without saying that the sewing method of the present invention can be applied to all cloths such as leather products, synthetic resins, synthetic fibers and the like. Moreover, although the reference numerals corresponding to the drawings are attached to the claims in the claims, the present invention is not limited thereto.

[0013]

As described above, according to the present invention, since the folding lines a and b of the two fabrics A and B are aligned on the same plane and sewn by the seam m, the fabrics A and B are heavy. Therefore, the step like the conventional lap stitch is not generated. Moreover, when stitching, the fabric A is sewn on the fabric B, so even if the fabric is not sewn again after splitting, the face to be the front side of the fabric is aligned in the same direction from the beginning. As a result, there is no kinking or wrinkling due to the unfolding of the fabric. Further, by applying the cloth C, the strength is the same as that of a piece of cloth. In addition, with a simple structure, it has become possible to draw a curve that freely connects two cloths with two identical parallel threads in terms of design.

According to the present invention, another cloth can be sewn on the edge of the collar of the suit, the sleeve opening, the pocket, etc. along the respective curved lines with a smooth surface, and the color and pattern of the different cloth can be appropriately selected. As a result, various designs can be easily applied even after being ready-made without breaking the shape of the clothing. Needless to say, three or more fabrics can be sewn into one fabric according to the present invention.
