ABSTRACT:
A method of producing a skin-covered pad for a seat, which includes by steps (a) preparing a lower mold which has a cavity formed therein, the mold having projections on a bottom of the cavity; (b) putting a bag-shaped outer skin member into the cavity, the skin member being thermally plastic; (c) putting an upper mold on the lower mold to close the cavity, the upper mold having an aperture formed therethrough; (d) projecting a press member into the cavity through the aperture, the press member having at its work head recesses which are shaped to match with the projections of the lower mold; (e) pressing the recessed work head of the press member against the projections of the lower mold with an interposal of a part of the outer skin member therebetween; (f) heating the work head of the press member thereby to soften the part of the outer skin member; (g) separating the work head of the press member away from the projections of the lower mold; and (h) pouring a liquid material for foamed plastic into the cavity and curing the same.
