ABSTRACT OF THE DISCLOSURE: A process for producing an electrically screened communication cable unit com- prising a pair of screening tapes surrounding a plurality of electrical conductors, each of such tapes comprising a sheet of high conductivit ?etal coated on its inner face with a thermoplastic resin and the tapes being bonded to- gether at their edges by heat sealing the respective inner faces together, which differs from prior art processes in that the conductors and the tapes with their thermo- plastic resin coated faces facing the conductors are fed to a forming and sealing zone where the tapes are formed around the conductors and sealed together at their faces. The tapes are sealed together at longitudinal ribs with a rib intermediate groups of conductors and may be sheared along an intermediate rib to provide two units each com- prising such tapes and a plurality of conductors. Also, apparatus for performing such process and the novel cable units produced thereby.
