Description

[Detailed Description of the Invention] [Objective of the Invention] Industrial Field of Application The present invention enables the outer fabric and the lining to be easily overlapped, and the hem of the outer fabric and the lining to easily form an edge without shifting the hem of the lining. The present invention relates to a method and device for serging lining that can be sewn.

Conventional technology Conventionally, a lining has been sewn on the front body of pants, and in order to maintain high quality when sewing the front and back bodies, the hem of the material has a front and back seam, and the material has two sides. In order to align the front side and the front side of the darning thread, it is necessary to overlock the outer fabric with the outer fabric facing up and the lining fabric facing down. Because of this, it is easy to move, twist, or wrinkle, and the lining is misaligned, making it difficult to overlap the lining.Also, the lining only goes halfway, and when sewing the hem, it has to go around the outer material. In places where the lining and lining exist together, at the border where the lining disappears, and in places where there is only the outer material, you can hem without any problems, but at the border where the lining exists in the middle of sewing from the hem of the outer material to the top, the hem of the lining may shift. However, it had the disadvantage that it was bent and overlapped.

Problems to be Solved by the Invention The present invention enables the outer fabric and the lining to be easily overlapped with matching patterns by fixing the hem of the lining, and also interposes a double-sided adhesive tape between the hem of the outer fabric and the lining. To provide a lining serging method and device which can easily hem the outer fabric and the lining without shifting the hem of the lining or overlapping the hem of the lining by crimp the outer fabric.

Outer material A and lining material B can be easily overlapped with matching patterns.

Also, separate the hem of lining B, apply double-sided adhesive tape M to the hem, return the hem, overlap outer material A and lining B, press the part to which double-sided adhesive tape M is applied, and then Since the edges will be overlocked, by temporarily fixing the hem of lining B, the hem of lining B will be fixed.
Even at the boundary where there is a hem of the lining B, the hem of the lining B can be sewn smoothly without shifting or bending.

In addition, since double-sided adhesive tape M was used as the adhesive, the material is limited to chemical fibers at high frequencies, the material changes color due to heat, and cooling time is required, but in the present invention, the outer material A and the lining material are B can be temporarily fixed without damaging the fabric, and if adhesives such as glue are used, there will be disadvantages such as thread waste sticking and nozzle clogging, but double-sided adhesive tape M does not have such disadvantages. In addition, the adhesive effect does not need to be strong because it is sewn immediately after temporary fixing, it is possible to use commercially available inexpensive double-sided adhesive tape M that can be easily obtained anywhere, and it is not as hard as a stapler. There is no need to remove it.

Also, separate the hem of the lower lining B, and add it to the table 2.
Since the rocking plate 5, which is a part of the table 2, is made to swing downward, the work on the table 2 can be facilitated even if only a small amount of the crimping mechanism 46 is present on the table 2. Its practical effects are enormous.
