  • Patent number: 4508585
    Abstract: The present invention comprises an improved apparatus and method for fabricating coaxial cable. Coaxial cable fabricated in accordance with the present invention comprises an inner conductive member encased in an annular electrical insulator, an outer electrically conducting sheath being annularly disposed about the insulator providing electrical shielding for the inner conductor. The improved apparatus and method for fabricating coaxial cable directs flattened malleable conductive strands for braiding the outer electrical sheath. The individual strands forming the braided sheath are each disposed about a cylindrical bobbin and fed about a pair of directing pins and positioners which position the flattened sheath material for entry into a braiding cone. Denatured alcohol lubricates the braiding cone during the braiding process in order to provide for uniform distribution of the braided sheath about the electrical conductor and insulator.
