<p>PROBLEM TO BE SOLVED: To weaken the cover material of multiple parallel lines and separate conductors separately for each insulated cable by clamping multiple parallel lines where many cables are joined with one another in parallel and in face form between the horn of an ultrasonic oscillator and a receiving metal fitting closely, and adding ultrasonic oscillation to the multiple parallel lines. SOLUTION: The ends of multiple parallel lines 2 where many insulated cables 1 are joined with one another in parallel and besides in face form are put closely between the horn of an ultrasonic oscillator 3 and a receiving metal fitting 3b, and ultrasonic oscillation is added to the parallel lines 2 by operating the ultrasonic oscillator 3. Hereby, rotation is generated around the axis of each insulated cable 1 of the parallel lines 2, and distortion is caused at the junction layer of the insulated cable 1, and this distortion changes into a crack, and the parallel lines 2 are separated for each insulated cables 1.</p> |
