Method of manufacturing a worked-wire product

Abstract

A method of manufacturing a worked-wire product from a wire ( ) including, all coaxially arranged, a core conductor ( ), an insulator ( ), an outer conductor ( ), a metal-evaporated film ( ) and a sheath ( ) is provided. The method comprises the steps of exposing a portion of the outer conductor ( ); holding the exposed portion at two positions by gripping with metallic foils ( ) and fixtures ( ); bending the outer conductor ( ) about a bending center (S) until it is circumferentially cut off, the bending being effected while applying ultrasonic vibrations on the outer conductor ( ) through the fixture ( ); removing the cut off portion of the outer conductor ( ) to expose a portion of the insulator ( ); and removing the exposed portion of the insulator ( ) to expose a portion of the core conductor ( ).
