Abstract

본 발명은 연속공급되는 내부도체상에 유전층을 압축하는 단계, 이와 같이 형성된 절연도체의 둘레에 종방향으로 인입되는 금속밴드를 슬릿을 가진 관으로 성형하고 슬릿을 가진 관의 종방향 모서리를 용접하는 단계 및 용접된 관을 유전층의 표면상으로 빼내는 단계를 포함하는 동축 케이블의 제조방법에 관한 것이다. 본 발명의 방법에서는 적어도 표면상에 플라스틱층을 구비하는 금속밴드를 사용하여 종방향 모서리의 용접을 레이저 용접에 의해 수행한다.The present invention comprises the steps of compressing a dielectric layer on a continuously supplied inner conductor, forming a metal band longitudinally drawn around the insulating conductor thus formed into a tube with a slit and welding the longitudinal edges of the tube with a slit And removing the welded tube onto the surface of the dielectric layer. In the method of the present invention, the welding of the longitudinal edges is carried out by laser welding using a metal band having at least a plastic layer on the surface.
