Abstract
In a method and device for combining a resin core member and a surface skin member at the same time as molding the resin core member into a desired shape, air and reaction gas trapped in the die cavity is removed through air vent pieces embedded in the die surfaces of the upper and lower dies so that a laminated molded article with a favorable appearance free from creases can be obtained. The air vent pieces may be either porous or provided with minute slits so that air and gas may be removed but the resin material may not seep through.
