Abstract
There is disclosed a process and apparatus for manufacturing flexible, shielded coaxial cable exhibiting improved magnetical screening capabilities wherein a tubular outer conductor is concentrically formed about an inner conductor with spacer means being disposed in the annulus between conductors. Accordingly, about the inner conductor including spacer means therefore, there is formed an inner component tube of a conductive material by the continuous forming in a lengthwise direction of a metal band into a tube having longitudinal edges welded together in a continuous, longitudinal welded joint. Concurrently, at least one further component tube is formed concentrically about the inner component tube by the lengthwise deformation of a second metal band of a ferromagnetic material into a second tube having opposed longitudinal edges which are also welded in a longitudinal direction in a continuous, longitudinal welded joint.
