Abstract
Materials with low dielectric loss factors, viz polyolefins, rendered susceptible to high frequency welding by incorporation adjacent to, or coated upon, a secondary material having a high loss factor, thus fusing the polyolefin by local heat transfer. The high loss material e.g. carboard may be pre-coated on one face with polyethylen, polypropylene, PVC or a polyurethane foam. Esp. for mfr. of composite sheet incorporating both moquette and polyolefin layers.
