PURPOSE:To obtain an interior decorative member without sags or breaking of shapes by a method in which a base member, a cushion member and the skin members of different kinds are laminated, and while causing this laminate to adhere under pressure by the molds with projected portions, high frequency voltage is applied to the specified parts of said skin members. CONSTITUTION:The surface of the cushion member 2 made of polyurethane foam, etc. is coated with an adhesive 3, and this cushion member 2 is placed on the base member 1 such as a hard board. Next, the skin members 4, 4' made of a synthetic resin leater and a cloth and placed on said cushion member such that a part of said resin is mutually polymerized. Thus, a laminate 10 is formed. Then, the laminate 10 is caused to adhere under pressure by the molds 20, 20' having the projected portions 21 for fixing a pattern and the conductive parts at the portions 21' of said projected portions 21, whereby each layer is caused to adhere along its whole surface. Further, high frequency voltage is applied to said conductive parts, and they are welded, thereby obtaining the interior decorative member. |
