PURPOSE:To manufacture a foamed resin molded body with a skin material by a method wherein the bag-shaped skin material is produced by sewing sheet-like material with expandable thread and, after the resultant skin material is arranged in a forming mold, foaming resin is poured in the mold so as to mold the molded body, the interior of the skin material of which is filled with the resin. CONSTITUTION:A sheet-like material 1 has a skin body 10 on its one side and a fluid shielding layer 12, which is integrally bonded on the other side or on the rear surface side of the skin body. The material 1 is cut into predetermined developed shapes. A plurality of the cut sheet-like materials 1 are sewn by expandable thread 2 so as to produce a bag-shaped skin material, and the expandable thread 2 at sewn part is expanded at least radially. Under the condition that the expandable thread is held in the expanded state, the skin material is arranged in a mold 6 so as to pour foaming resin from the opening of the skin material 1' in order to press the skin material against the molding surface of the mold by means of the blowing pressure of the foaming resin and at the same time to fill the interior of the skin material for forming a molded body. As a result, gap between the sheet-like material and the thread is prevented from developing, when tensile force is applied to the skin material at time of forming. Thus, the oozing-out of the foamed resin can be prevented. |
