<p>PURPOSE:To avoid a poor welding and to make a finishing appearance better, by melting and removing or laying down in advance piles of surroundings on an ornament fabric where a synthetic resin skin material is welded to make the thickness thinner. CONSTITUTION:An ornament fabric 4 is, for example, vacuum adsorbed on a weld top force 9 having an outline shape and is pinched under pressure with a welt bottom force 10 to melt piles of surroundings to make the thickness thinner. The ornament fabric 4 and a base material 3 are adhered each other and the mold is then opened. In another method, instead of melting, the piles are laid down to make a thin thickness part 4a. This base material 3 is set on a bottom force 1 and a laminated synthetic resin skin material 11 comprising a vinyl chloride resin film and a vinyl chloride resin foam is molded and adhered on the surface of the base material 3. The base material 3 is transferred on a receiving mold 12 and the part of the skin material 11 to be laminated with the edge part of the ornament fabric 4 is welded to the thin thickness part 4a by means of high frequency welding. Extra part of the skin material 11 is fused away to prepare a product which has excellent joint strength and good appearance.</p> |
