ABSTRACT:
A method of molding a skin-covered foamed plastic article, which employs an elastically deformable belt for assuring a positioning of a bag-shaped skin member in a mold during a molding process. The mold has in the cavity thereof at least one longitudinally curved elongate ridge for providing engagement with a stitched portion of the skin member. The belt is connected to an inner wall of the bag-shaped skin member, so that upon proper placement of the skin member in a mold, the belt is expanded thereby to press the stitched portion against the elongate ridge of the mold. With this, the skin member is tightly held in the mold during curing or foaming process of a liquid material in the mold.
