〔Effect of the invention〕

In short, in the present invention, the lining B is placed on the table with the hem fixed, and the outer material A is placed on top of the lining B, so that the entire lining B and the hem do not move or shift. It is possible to easily overlap the lining B and the lining B by matching the patterns.

Also, separate the hem of the lining B, apply double-sided adhesive tape M to the hem, return the hem, stack the lining B on the outer material, press the part to which the double-sided adhesive tape M is attached [O], and then Since the hem of the lining B is hemmed, by temporarily fixing the hem of the lining B, the hem of the lining B can be sewn smoothly even at the boundary where the lining B exists when overtaking the hem 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 Can be temporarily fixed without damaging the fabric of B.
In addition, if adhesives such as glue are used, there will be disadvantages such as thread waste adhesion and nozzle clogging, but double-sided adhesive tape M can prevent such defects and also allows for temporary sewing. Therefore, the adhesive effect does not need to be strong, and a commercially available, inexpensive double-sided adhesive tape M that can be easily applied by hand can be used anywhere, and since it is not as hard as a stapler, there is no need to remove it.

In addition, the hem of the lower lining B is separated, and the rocking plate 5, which is a part of the table 2, is made to swing downward, so there is a slight crimp mechanism 46 on the table 2. The practical effects of this, such as being able to make work on the table 2 easier, are tremendous just by doing so.
