Description

[Detailed Description of the Invention] (Industrial Application Field) This is an invention for sewing fabrics such as clothing and futons in a curved manner.

(Prior art and its problems) It is well known in the field of overlapping stitching such as appliqué to sew a piece of fabric with a curved cut line to another piece of fabric along the cut line.

However, when two pieces of fabric are sewn together, a step is created at the seam, which not only significantly damages the shape of the garment, but also prevents smooth ironing as the iron gets caught in the step. In addition, the iron hits only the top of the stepped portion, causing inconveniences such as leaving press marks on the stepped portion.

In order to eliminate such stepped portions at the seam part, as shown in Figure 8, two pieces of fabric p and q are cut into curved lines that fit into each other, such as concave and convex patterns, and One possible method is to sew along the cutting line with the front sides of the fabrics p and q facing each other, and then divide the front surfaces of the fabrics p and q left and right.

According to this method, when the fabrics P and q are divided, they do not overlap, so the step part is eliminated, but the seams of the fabrics p and q are concave curves on one side and convex curves on the other, so they are different.
It is extremely difficult to sew while aligning the positions, and furthermore, when the sewn fabrics P and Q are split, the seams become taut or sag, and the fabric wrinkles, making it difficult to finish beautifully.

The present invention solves these conventional problems by sewing two pieces of fabric together along a curved line so that there are no stepped sections, and at the same time, it is possible to prevent the fabric from twisting or wrinkling at the stitching point. The purpose is to

(Means for solving the problem) In the present invention, the end of one fabric A is folded back by a predetermined width to form a fold line a along an arbitrary curve, and this fabric A is folded back to the other fabric B. After connecting fabrics A and B by stacking them on top and sewing near the folding line a with a stitch m along the curved shape, the part of fabric B that overlaps with fabric A is sewn along the stitch m on the back side of fabric B. The fold line a of the fabric A is fitted into the fold line of the fabric B thus formed so that they are aligned on the same plane.

(Function) According to the sewing method of the present invention, the seam m for sewing fabrics A and B runs along the folding lines a and b of both fabrics A and B. Since the fabrics are lined up next to each other without gaps and on the same plane, overlapping of the fabrics is eliminated, and there is no need to separate the two pieces of fabric after sewing, the two pieces of fabric can be sewn together without any twists or wrinkles. A and B are sewn into one piece along the curved seam m.

(Example) Next, embodiments of the present invention will be described with reference to the drawings.

A and B are fabrics to be sewn, such as suit fabrics. First, one fabric A is cut along a predetermined appropriate curve (Fig. 2), and a certain length is cut from the cutting line l, for example, 7+a/ Fold the edge of fabric A to its back side along folding line a parallel to cutting line 1. In this case, turn fabric A inside out and insert the cutting line Apply a hard paper pattern 2 with the same shape as 1 and apply the cloth along the periphery of the pattern 2! ! By ironing from above while folding A, you can efficiently create a precisely curved fold line a.

Next, lay this fabric A on top of fabric B with the folded part facing down, and sew along folding line a about 1 to 2 m/m inside of folding line a using a sewing machine to connect fabrics A and B. (Figure 4) The position of the seam m on this sewing machine varies depending on the material of the fabric, and if the fabric has long piles and frays easily, it may be necessary to sew deeper than the fold line a, but it is preferable to sew it as close to the fold line a as possible.

After connecting fabrics A and B in this way, fabric B, fabric A
Cut off the overlapping part with scissors leaving approximately the same width as the folded part of fabric A (Figure 5), then fold the cut end back onto the back side of fabric B along seam m (Figure 6). In this case, turn fabrics A and B inside out, fold back the edge of fabric B while ironing along seam m, and make a cut 3 with scissors in the folded part corresponding to the outer circumference of the curve. The edge of fabric B can be folded back (FIG. 7), and it goes without saying that the edge of fabric B may be cut in advance along the planned seam m before sewing.

After folding the end of fabric B, pull fabrics A and B slightly in opposite directions to loosen the seam m, and push the folded lia of fabric A into the folded b of fabric B, making both folds jllia and b. Arrange them adjacently on the same plane without any gaps (Figure 1).

In this case as well, if the seam m is pressed with an iron, the folding lines a and b can be easily aligned on the same plane.

Note that when the fabrics A and B follow a curved surface, the folding lines a and b naturally also follow the same curved surface.

(Effect) According to the present invention, the folding lines a and b of the two fabrics A and B are lined up on the same plane and sewn together by the seam m, so the fabrics A and B do not overlap. Therefore, there is no step like the conventional overlapping method.Furthermore, when sewing, fabric A is layered on top of fabric B, so there is no need to separate the two fabrics and unfold them again after sewing. Since the sides that should be the front side of the fabric are aligned in the same direction,
This has the effect of eliminating the occurrence of twists and wrinkles as the fabric unfolds.

By using the present invention, as shown in FIG. 9, arbitrary curves 4.5.
Separate fabrics can be sewn together along line 6 with a smooth surface, and by appropriately selecting the color and pattern of the separate fabrics, various designs can be easily applied without changing the shape of the clothing.

In addition, the wide width can be applied to futon covers, patchwork, patchwork, decorative cloth covering the core of buttons, etc., and it can also be used not only for sewing fabrics but also for sewing leather and aluminum foil.

It goes without saying that three or more pieces of fabric can be sewn together into one piece according to the present invention.
