には必然的に人的要素が加わるため工程の自動化
その他の合理化には限界並びに制約がある。 The conventional technique for coating a polyurethane foam molded body with a skin material is to apply a synthetic resin paint to the inner surface of a polyurethane foam mold in advance to form a skin layer, and then foam-mold the polyurethane inside the mold. There is a method of integrally covering the surface of the molded object with a skin layer by carrying out a method of forming a bag-shaped skin layer made of synthetic resin as a base material in advance, separate from the polyurethane foam molding process, and then using this skin layer. There are two main types of methods: coating a polyurethane foam molded article with a predetermined shape. However, when the above technique is used in a product such as a seat made of a polyurethane foam molded product, which is frequently subjected to compressive deformation stress, there is a drawback that the skin is poor in durability and easily peels off from the surface of the molded product. Therefore, for products that undergo frequent compression deformation, it has been necessary to apply a skin to the molded product using the above-mentioned technique. However, the above-mentioned technology is further divided into several methods, but all of them require complicated equipment and equipment costs, and since the work of covering the skin inevitably involves a human element, it is difficult to automate the process or use other methods. There are limits and constraints to rationalization.

程の合理化には限界があることであつた。 Each of the above methods (a) to (d) has the disadvantage that the equipment used to carry out the method is complicated and the equipment cost increases, and method (e) requires a lot of time for the sewing process. Moreover, it is not satisfactory from the viewpoint of aesthetics and maintenance of watertightness. Moreover, regardless of the method used, it is commonly pointed out that manual work is essential to attach the bag-shaped skin to the polyurethane foam molded product, and therefore, it is difficult to streamline the process. There was a limit.

な利点も有する。 As described above, according to the skin forming method according to the present invention described above, the skin is directly formed on the outer surface of the polyurethane foam molded article, so unlike the above-mentioned method according to the prior art, the skin cannot be formed manually. The complicated labor involved in adhering to the molded body is completely eliminated, and the production process is streamlined through full automation. In addition, since the synthetic resin powder is attached to the outer periphery of the polyurethane foam molding and then melted to form the skin layer, even if the external shape of the foam is complex, including undercuts, the skin layer will remain intact. It can be formed easily and does not wrinkle, giving an extremely elegant appearance. Furthermore, the heat applied to the molded object while traveling through the infrared heating tunnel is stored on the surface of the polyurethane foam, which is also an insulating material, so it melts the thermoplastic synthetic resin powder adhering to the molded object extremely efficiently. be. In addition,
The method of the present invention does not require a skin molding mold such as a vacuum molding mold, and does not use expensive equipment with complicated mechanisms such as welder molding machines or vacuum molding machines, so equipment costs can be kept low. It also has additional advantages such as.
