Method of making electrical cable
Abstract
Abstract THIS IMPROVED METHOD OF MAKING ELECTRICAL CABLE HAS A CABLE JACKET FORMED BY A TAPE FOLDED LONGITUDINALLY AROUND THE CORE OF THE CABLE; AND THE TAPE IS A LAMINATION OF A VERY THIN STRIP OF METAL, SUCH AS ALUMINUM OR COPPER, WHICH SERVES AS A VAPOR BARRIER, WITH A COATING ON BOTH SIDES OF THE METAL OF MUCH GREATER THICKNESS THAN THE METAL AND BONDED DIRECTLY TO THE METAL, PREFERABLY BY A "CHEMICAL BOUND." A LAP SEAM IS PREFERABLY REINFORCED BY A LONGITUDINALLY EXTENDING PLASTIC-METAL LAMINATE TAPE UNDER THE SEAM AS A "BRIDGING STRIP" WITH PLASTIC COATING AND THE CONFRONTING FACES OF THE SEAM ARE HEAT-SOFTENED AND PRESSED TOGETHER TO BOND THE EDGE PORTIONS OF THE SEAM TOGETHER.
