Description

Description: TECHNICAL FIELD The present invention relates to a stitch guide and a sewing method using the stitch guide, and particularly to sewing of fabric used for indoor and outdoor and vehicle seats, interior materials and the like. The present invention relates to a stitch guide suitably used for sewing a sewing allowance and a fabric again after the ground stitching, and a sewing method using the stitch guide. In this example, the fabric is a generic term for sheet-like materials used for indoor and outdoor, vehicle seats, interior materials, etc., regardless of material, woven fabric, non-woven fabric, synthetic resin, and the like.

2. Description of the Related Art Conventionally, for example, when sewing a skin material of a vehicle seat or the like, after performing ground stitching, the seam allowance and the skin are again sewn to increase the strength of a sewn portion. I have. That is, as shown in FIG.
Sew it together from the back and sew it together from behind (ground sewing), and divide the seam allowance 61 left and right as shown in FIG. The guides 65 and 66 of the sewing needle come into contact with the sewing machine, and sewing is performed by the upper and lower guides.

[Problems to be Solved by the Invention] In the sewing method as described above, in the sewing after the ground stitching, sewing is performed using a slight stitch groove or fold of the ground stitch as a guide. For this reason, not only is it necessary for skilled workers, but also the soft part called the seam of the fabric was pressed by the upper and lower guides, so even for skilled workers,
As shown in FIG. 8, there is an inconvenience that the stitches meander or the stitch pitches of the left and right stitch portions are shifted, resulting in quality variations.
If such an inconvenience occurs, it is necessary to return the product or re-stitch the product.

SUMMARY OF THE INVENTION An object of the present invention is to provide a stitch guide capable of performing sewing without requiring skill and without generating meandering of a sewn portion and depending on the skill of an operator, and a sewing method using the stitch guide. .

[Means for Solving the Problems] A stitch guide according to the present invention is used when sewing at least two pieces of fabric, and then sewing the seam allowance and the fabric again on the side of the ground stitch. A needle guide, wherein the guide is formed by sewing a long head, a thin comb-like leg integrated with the head, and the leg at the time of the ground sewing; The presser guide on the side is guided by the head.

The sewing method according to the present invention further includes a first step of ground-stitching at least two pieces of cloth, and a second step of sewing the seam allowance and the cloth again on the side of the ground stitch after the ground stitch. In the first step, the legs of a stitch guide comprising a long head and a thin comb-shaped leg integrated with each other are sewn together, and in the second step, The stitch guide is sewn by guiding the presser guide on the sewing machine side with the head of the stitch guide, and then the stitch guide is removed.

[Operation] Since the stitch guide of the present invention has a long head, the presser guide on the sewing machine side is guided by the head of the stitch guide, and sewing can be performed along the stitch guide. In addition, the stitch guide is considerably sewn to the legs at the time of the ground stitching, and the legs themselves are formed into a thin comb shape, with the thin comb-shaped legs integrated with the head. Therefore, it is not stitched with a thread, but is sandwiched between cloths. For this reason, the stitch guide which has finished guiding the sewing needle can be easily removed.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The members, arrangements, and the like described below do not limit the present invention, and can be variously modified within the scope of the present invention.

The stitch guide according to the present invention is a guide for a sewing needle that is used when sewing two or more fabrics, and then sewing the sewing allowance and the fabric again on the side of the ground stitch, As shown in FIG. 3, the stitch guide 1 of the present example is composed of a head 2 having a long spherical surface and a large number of thin comb-shaped legs 3 integrated with the head 2. I have.

In order to sew so-called double stitches using the stitch guide 1, a first step of sewn two or more fabrics 4, 5 and after the sewn in the first step , Seam allowances 4a and 5a, and second sewn the fabrics 4 and 5 again
In the first step, the legs 3 of the stitch guide 1 are sewn together. In this manner, the leg 3 of the stitch guide 1 is sewn together with the ground sewing, and the head 2 of the stitch guide 1 is
It will be arranged along the 5 stitch (boundary part). Next, at the time of the second step, in this example, the bias tape 6 is placed on the sewing machine base 7, and the stitch guide 1 is held by the holding guide 8 disposed between the sewing needles H on both sides. Head 2
When the stitches are guided and sewn, the stitches are sewn along the stitch guide 1. Thereafter, with the head 2 of the stitch guide 1, the leg 3 is pulled out and removed.

In the above embodiment, the holding guide 8 is formed so as to match the head 2 of the stitch guide 1, and the shape of the head 2 of the stitch guide 1 is changed to a semicircular cross section in the above embodiment. Although the recess 8a is used, when the head shape of the stitch guide 1 is made to have a long rectangular cross section or the like,
The holding guide is also a rectangular recess so as to match the shape of the head of the stitch guide.

FIG. 5 shows another embodiment of the present invention. In the above embodiment, an example of a so-called double stitch was described.
In this example, the case of single stitch is shown. The same members and the like as those in the embodiment shown in FIGS. 1 to 4 are denoted by the same reference numerals, and description thereof will be omitted.

In this example, the so-called single stitch, in which two cloths 4 and 5 are sewn, and sewing margins 4a and 5a of the two cloths 4 and 5 and one of the cloths (cloth 4 in this example) are sewn. The stitch guide 11 of the present example has a long head 12 having a semi-cylindrical cross section, and a large number of thin comb teeth 13 extending horizontally from one lower end of the head 12. It is composed of Also, the presser guide 18 of the sewing machine
Is formed so as to cover the head 12 and one side surface.

When the stitch guide 11 as in this embodiment is used, so-called single stitch sewing can be performed in the same manner as in the above embodiment. In this example, an example in which two pieces of cloth are used is shown. However, in a case where a plurality of pieces of cloth are used, the same operation and effect can be obtained by sewing the stitch guide legs together between any two pieces. To play.

[Effects of the Invention] Since the present invention is configured as described above, the use of the stitch guide according to the present invention does not require skill and does not cause meandering of the sewn portion. Without depending on the skill level, it is possible to easily sew the sewing allowance and the cloth again after the ground sewing. In addition, since no skill is required, it is possible to provide a sewn product without variation in quality.
