摘要: The method for forming a resilient pad from plurality of plastic foam sheet members comprises stacking such above one another within press with their adjacent surfaces touching, compressing the together under an initial pressure 5 pounds to 20 per square inch, applying heat until they reach uniform temperature throughout thicknesses 250*-300* F., increasing exerted by on between 30 and 100 inch cause fuse into unitary construction. A second embodiment invention includes sandwiching layer shredded materials before application pressure. Fibrous selected group consisting glass fibers, acrylic cotton, jute, wool, sisal may be mixed catalyzed resin sandwiched
