Abstract:
    The invention concerns a process for manufacturing cables incorporating a polymeric core obtained through extrusion and reinforced with a metallic rope, wherein transmissive elements, constituted by optical-fibres and/or electrical conductors, are embedded. The transmissive elements have an open-helix configuration with respect to the cable axis, and said configuration is imparted to them through submitting, inside an extruder-head, or near its exit opening the polymeric material while yet in its pasty-state and which has just been embedded in them, to an alternate rotatory motion with respect to the axis of the cable. There follows, downstream of the extruder-head, a quick cooling of the polymeric material, which stably blocks threin, the transmissive elements having the open-helix configuration previously imparted to them. The invention also comprises a production-line which carries out this process.
