PURPOSE:To make it possible to use sharp groove shape in a decorative design and at the same time contrive to improve the bonding strength between a skin material and a foam by a method wherein polyurethane foaming stock liquid is applied in the form of a flat plate and the foaming of the stock liquid and the integration of the skin material and the foam are done simultaneously and, in addition, the shaping is done also during the integration. CONSTITUTION:There is no special limitation as a skin material 1. However the preferable skin material is a synthetic resin sheet such as polyvinyl chloride sheet or the like. When necessary, on the surface of said sheet, thermoplastic synthetic resin fiber is flocked or decorative pattern is applied by embossing. The preferable thickness of polyurethane foamed layer 2 is about 2-30mm. The preferable depth of the groove is about 1-15mm. The preferable density of the foamed layer is in the range of 0.04-0.12g/cm<2>. The shape relieving is done simultaneously with the integration of a surfacing material and a foam. As the method for the shape relieving, the method such as to press the skin material with a pressing jig having a shape conforming to the shape of the surface of a product is exampled. |
