Next, the thermoplastic synthetic resin sheet leather is high-frequency welded along the outer edge of the core plate, and then the thermoplastic synthetic resin sheet below the folding area of the leather is removed, and then the folding area of the leather is made of thermoplastic synthetic resin. The present invention attempts to solve these problems by providing a method for manufacturing a cover body and a case face plate, which are characterized in that they are folded and pasted onto the bottom surface of a sheet.

At the same time, the sponge sheet 8 as an elastic body is further polymerized, and a leather 9 as an outer sheet having a size extending outward from the outer edge of the hard paper 7 by a folding allowance 9a is placed thereon.
Cover. Next, (B) the upper electrode 10 of the high-frequency welder is applied to a position along the outer edge of the hard paper 7 to high-frequency weld the vinyl chloride sheet 6 and the leather 9 (numeral 11 in the figure indicates the high-frequency welding location). And (C)
The end piece 6a of the vinyl chloride sheet 6 existing on the lower surface side of the folding allowance 9a of the leather 9 is peeled off from the outer boundary of the high-frequency welding area 11 which has become thin due to high-frequency welding, and the width of the folding allowance 9a of the leather 9 is removed. Glue 12 is applied to the lower surface of the vinyl chloride sheet 6 (double-sided adhesive tape or the like may be applied instead of glue). Finally, (D) the folding margin 9a of the leather 9 is folded back to the lower surface side of the vinyl chloride sheet 6 serving as the inner sheet and the film is completed.

決することができる効果を奏するものである。(Operations and Effects) The present invention has the above-mentioned configuration, and firstly, in the conventional manufacturing method, the inner sheet 2 and the outer sheet 3 were fixed by gluing, whereas the manufacturing method of the present invention In this method, the thermoplastic synthetic resin sheet as the inner sheet and the leather as the outer sheet are high-frequency welded, which eliminates the need for applying glue, which is necessary in conventional manufacturing methods, making the work simple and quick. However, since the thermoplastic synthetic resin sheet as the inner sheet and the leather as the outer sheet are integrated by high-frequency welding rather than gluing, their adhesion is stronger and can be used for sewing, etc. as in the past. Therefore, there is no need for reinforcement, and in order to tightly fix the side edges without loosening them, the conventional manufacturing method requires work that requires skill, such as folding and crimping the folding margin 3a with a strong tension. However, according to the manufacturing method of the present invention, since the side edges are tightly determined by high-frequency welding, the folding margin can be simply pasted, making the work easier. As a result, work efficiency can be improved and product quality can also be improved.
The present invention has the effect of being able to sufficiently solve the above-mentioned problems.
