摘要:
An improved process for producing a laminated resin foam composed of two resin foam layers of different characteristic properties wherein the layers are integrally bonded together. A first foamable resin liquid for forming flexible foam is poured into a first space in a foam processing mold on one side of a barrier projecting from the wall of the mold and pouring a second foamable resin liquid for forming a foam less flexible than the first flexible foam into a second space in said foam processing mold on the other side of said barrier. The two foamable resin liquids foam beyond the barrier into contact with each other to form the two laminated foam layers. One improvement in the process includes wetting a substantial portion of the mold cavity with the first foamable resin liquid. Various shapes of molds and barriers will produce different shapes and characteristics of the resultant foam pad, such as for a car seat.
