  • advancing an elongate center conductor along a predetermined path of travel into and through an extrusion head and extruding a foamed polymer onto the center conductor to produce a foam dielectric surrounding the center conductor;

    advancing the foam dielectric covered center conductor from the extrusion head to a foil shield wraping station and wrapping an electrically conductive foil shield around the foam dielectric;

    advancing the foil wrapped dielectric from the foil wrapping station to a reinforcing wire covering station for arranging a plurality of flat reinforcing wires around the foil shield; and

    continuously advancing the thus formed article from the wire covering station to a jacketing station located in tandem with the wire covering station and extruding a protective jacket over the wire covering.
