           After the initial section 11 of coating 12 is stripped to ex-
         pose a section of wire cable 14, the coated cable 13 is ad-
         vanced to the left and a metal barrel 16 is placed in position
         over the stripped section 11 on the swaging die 40. The bar-
         rel 16 is then held in position by the bottom and top locators
         41, 42 and swaged to secure it to the wire cable 14, while the
         stripping die 20 simultaneously operates to cut the coating
