发明名称 METHOD FOR PRODUCING PAD FOR SHEET
摘要 PROBLEM TO BE SOLVED: To inexpensively without lowering moldability produce a pad for a sheet in which a surface layer material is molded integrally with a pad main body in a method for producing the pad in which a polyurethane raw liquid is injected into a molding mold and subjected to foaming. SOLUTION: The molding mold 10 having a lower mold 12 for molding the back side of the pad and an upper mold 16 which can be opened/closed in relation to the lower mold and molds the design surface side of the pad is used. The surface layer material 2 for forming at least a part of the design surface of the pad is arranged in the upper mold 16, and the polyurethane raw liquid M is injected into the molding mold 10 with the surface layer material 2 arranged so that the surface layer material 2 is integrated with the pad main body 1.
