All of the decorative pieces shown in these publications are adhered to an adherend cloth such as cloth for clothes or cloth for bags by using a high frequency welder.

In addition, a sewing means is also adopted for the cloth to be attached by cutting the decorative piece along the outer contour to a wide extent and sewing it with a sewing machine.

Problems to be Solved by the Invention Since the synthetic resin decorative piece disclosed in the above publication is adhered by a high-frequency welder, the cloth for clothing or bag material is brought into a high-frequency welder processing factory and processed. However, there is a drawback that the transportation cost increases.

In addition, the base material of the publicly known synthetic resin decorative piece is cut slightly wider than the outer contour of the decorative piece and is sewn to clothes, bags, gloves, etc. by sewing with a sewing machine. There is also a drawback that the outer peripheral edge part warps upward because the decorative pieces are pulled by the sewing thread and the sewing needle is pierced at the part other than the adhesive part. There is a possibility that water or washing liquid may penetrate into the decorative piece, and a decorative piece having a complicated outer shape is difficult to sew, peeling is likely to occur due to thread breakage, and the fixing strength is relatively weak. In addition, it takes time to sew and the cost is high, the sewing time varies depending on the size and outer shape of the decorative piece, and the difference in sewing time and the finish depend on the skill level of the operator. There is a problem such as a difference in quality. Therefore, according to the present invention, the decorative piece made of synthetic resin can be firmly, beautifully, and highly efficiently produced by only one operation called a heating press, regardless of the shape, size or skill level of the operator. Adhere to bags, gloves, etc.,
Moreover, it was invented for the purpose of providing a method capable of swelling the pattern portion to give a three-dimensional pattern by the bonding step.

Then, the outer contour line 19 and the pattern contour line 20 are adhered to the base material 18 via the synthetic resin foam sheet 17 by the high-frequency welder, and the adhesive film 21 is further adhered to the lower surface of the base material 18. The synthetic resin foam sheet 17 and the adhesive film 21 described above are made of the same material as that used in FIG. 3, but the one forming the surface layer 16 is the adhesive film 21.
It may be the same adhesive film as the above or the same material as the synthetic resin sheet 7 shown in FIG.

The ornamental body 14 shown in FIG. 5 is obtained by omitting the synthetic resin foam sheet 8 from the structure of the ornamental body 1 shown in FIG. 3, and the other structures are the same as those shown in FIG. It is a thing.

In any of the decorative pieces having any structure, the decorative piece was placed on the upper surface of the adherend fabric and heated and pressed from the front side of the decorative piece. It is not possible to obtain strength and appearance.

As described above, the bulged synthetic resin sheet contracts in its bulging form due to a decrease in internal pressure due to the contraction of air or the like due to cooling, but some bulging shape remains and forms a gentle three-dimensional pattern.

Effect The present invention has the structure and operation described above, and has the effect of adhering to the material to be adhered on the entire lower surface of the base material instead of sewing, so that the appearance is beautiful and the adhesive strength is significantly increased.

In addition, regardless of size or shape, it can be bonded in a short time in one step, and regardless of the skill level of the worker, a uniform quality bonding structure of decorative pieces can be obtained in a simple process, thus improving work efficiency. There is also an effect of improving the cost and reducing the cost.

Further, since the decorative pieces can be carried into the sewing factory for clothes, bags, gloves and the like and adhered to each other, there is an effect that the transportation cost when the cloth to be adhered is carried into the high frequency welder factory can be reduced.

Furthermore, since no sewing machine needle is used, no needle penetration hole is created,
The effect is that there is no risk of water or washing liquid entering the decorative piece.

Further, when the decorative piece is heated and pressed by the pressure plate, the air sealed between the synthetic resin sheet and the base material expands, and the synthetic resin sheet swells to press and deform the pressure receiving plate.
There is also an effect that the swelling pattern of the decorative piece before being adhered to the material to be adhered is not crushed at the time of heating and pressing, and is reliably preserved even after being adhered to the material to be adhered.
