なわれている。≪Prior art and its problems≫ A skin material, especially a skin material having a closed-cell foam layer, is integrally pasted along the curved surface of a long core molded product formed into a required curved shape. The method for attaching the core material is to form a number of air vent holes at appropriate positions in the core material molded product, place the core material on the mold surface of a vacuum mold that communicates with a vacuum suction device, apply adhesive, and then The above-mentioned skin material is installed on the core molded product, and then the air accumulated between the core molded product and the skin material is discharged by operating the above-mentioned suction device, and the skin material is pasted along the curved surface. There are methods of wearing clothes.

されている。 However, in this pasting method, since the foam layer is of a closed cell type and the adhesive is applied over the entire surface of the core molded product, as shown in Figure 1, At the location where the air vent hole 1a of the core molded product 1 is not formed,
Air pockets 4 are surrounded by the skin material 2, the core molded product, and the adhesive layer 3 in some places and are formed in the form of islands, which appear as bulges 4a on the surface of these areas, and the adhesive strength is also reduced. Shortcomings have been pointed out, such as:
この場合、芯材成形品１に無数の空気抜き穴を
設けるか、あるいはエア溜り４の形成される箇所

で、その都度エア溜り４を確認しながら設けなけ
ればならず、現実的な方法ではない。 In this case, it is necessary to take measures such as providing countless air vent holes in the core molded product 1 or providing air holes at the locations where the air pockets 4 are formed, but in the former case, the strength of the core material decreases. However, in the latter case, since the air pockets 4 are not necessarily formed at a fixed location, the air pockets 4 must be checked each time they are installed, which is not a practical method.

0 has a trapezoidal shape, and a large number of air vent holes 12 are formed on the mold surface 10a that communicate with the vacuum suction device 11. On this mold surface 10a, there is a core material formed by pressing etc. in the entire process. Molded product 13
is placed. Air vent holes 14 are formed in this core molded product 13 at positions corresponding to the air vent holes 12, and, for example, flat portions 13a and sloped portions 13 are formed at appropriate intervals in the longitudinal direction shown in FIG.
b, 13b are formed in a row. Further, these air vent holes 14 can be punched simultaneously during the above-mentioned press working.

5 is placed on the core molded product 13. This masking plate 15 has a masking pattern formed to cover the rows of the air vent holes 14, and if adhesive is sprayed from the top of the masking plate 15, the ridge line and edge line will be applied onto the core molded product 13. Along the pattern of adhesive layer 16 as shown in FIG.
is formed, and due to the thickness of the adhesive layer 16, grooves 14b are formed in which the rows of air vent holes 14a communicate with each other on the surface of the core material formed product 13, that is, grooves 14b are formed by the unpainted portions.

せるようにすることも可能である。 Note that it is also possible to apply air pressure to the skin material 17 at the same time as the vacuum suction, and to adhere the skin material 17 by the back pressure and vacuum suction.
本願発明方法によれば、上記の如くエア溜まり
の発生を防止することができるが、その理由は下
記の如くであると推察される。 According to the method of the present invention, the occurrence of air pockets can be prevented as described above, and the reason for this is presumed to be as follows.

で、エア溜まりの発生を防止することとなるので
ある。 That is, during vacuum adhesion, the skin material first adapts to the convex portions and edge portions of the core molded product, and then to the flat portions and concave portions. Since the air in the previously acclimated area is exhausted through the air vent holes and grooves, there is no risk of air pockets forming, but the problem is the air remaining in the grooves. That is, since the foam layer of the skin material is soft, it will fit into the groove immediately by vacuum suction, but in the present invention, air vent holes are provided at appropriate locations within the groove (air vent holes of the suction device). Because of this, the air that accumulates in the groove is discharged through this air vent hole. As a result, the air discharge path is not blocked, thereby preventing the formation of air pockets.
