Abstract

In the air-pressure molding method according to the present invention, a laminated material is arranged, when in a heated and softened state, on the shaping face of a mold having an air reservoir, and the portion to be molded is hermetically sealed within a box-shaped top cover. Air under pressure higher than atmospheric pressure is then applied to the inside of the top cover so that the laminated material is developed and shaped to have a uniform thickness on the air-cushion layer which is established by the air pressure between the laminated material and the shaping face of the mold. Immediately after, the air in the cushion layer is forced to the air reservoir thereby bringing the laminated material into contact with the mold so that the surface of the skin may be reversely embossed or stitched.
