    摘要: Metallic load-carrying elements (3, 23) are helically spun around a central member (1, 21) comprising a supporting member or members (9, 24) constituting a structure (4, 24) which defines at least one passage (6, 26) wholly accommodating at least one electrical or optical transmission element (7, 27). The transmission element is thereby protected against stresses applied to the load-carrying elements. The central structure is radially and longitudinally self-supporting. The central member (1, 21) is formed by causing the supporting member or members (9, 24) and the transmission element or elements (7, 27) to converge to a point from which the central member (1, 21) is withdrawn continuously. The load-carrying elements (3, 23) are subsequently applied to the central member (1, 21). Cales of practically unlimited length can be produced.
