PURPOSE:To make press forces relative to a skin material exert even on a ridged part between mutually intersecting side wall surfaces in a product core on the low frictional area, and prevent the occurrence of creases being likely to arise in the prior art by pressing down a sheet-like skin material and an upper mold situated upside thereof on an article core from the side of an upper surface. CONSTITUTION:A jig is to stick a skin material 2 on the outer surface of a box-typed article core and, on the lower mold 3 to be attached with the box- typed article core, a truncated pyramid type blank holder part 6 is provided and in the proximity to the ridges of the blank holder part. a low frictional area 7 is provided, and then a press member 16 is provided on an upper mold, which acts to hold the ridges relative to the skin material 2 located on the low frictional area 7 and press down in the direction of spreading them to both sides. |
