って製作作業性を悪くする欠点となっだ。For example, trim panels for automobile interiors are made by layering a hard fiber layer, a polyurethane foam layer, and a soft skin and heat forming them into a predetermined shape, but the outer periphery is simply bent to the back side. If only pinned, wrinkles and overlapping lines will occur, and lack of sharpness will cause a poor appearance as a trim board product. Therefore, as shown in Fig. 10, the foam layer of the trim board 60 is usually pressed. 67, the outer peripheral part 37A is the first
A part of the zero foam layer 67 is bent and pinned toward the hard layer 66 on the back side as shown by the imaginary line in FIG. 11. However, cutting off the outer periphery 37A of the foam layer 67 of the pressed trim plate 60 is troublesome and time consuming, which has the disadvantage of reducing productivity. Therefore, at the end of the pressed trim plate, the hard fan end and the foam layer end are aligned so that only the outer skin protrudes outward, and the protruding outer skin is bent to the back side. Although a processing method can be considered, it is difficult to match the ends of the hard layer and the foam layer after molding, and this has the disadvantage of worsening the manufacturing workability.
