Abstract: A method, an extrusion apparatus and a plant for continuously manufacturing a communication cable. A plurality of twisted pairs of insulated conductors are housed in respective cavities longitudinally formed within an elongated integral body. The cavities have a substantially circular cross-section and maximum diameter adapted to prevent any relative movement of the twisted pairs of insulated conductors with respect to one another, while each of the pairs of insulated conductors is substantially free to move within the cavities along the longitudinal direction of the cable.

Abstract: A method, an extrusion apparatus and a plant for continuously manufacturing a communication cable. A plurality of twisted pairs of insulated conductors are housed in respective cavities longitudinally formed within an elongated integral body. The cavities have a substantially circular cross-section and maximum diameter adapted to prevent any relative movement of the twisted pairs of insulated conductors with respect to one another, while each of the pairs of insulated conductors is substantially free to move within the cavities along the longitudinal direction of the cable. Advantageously, the communications cable has both the desired electrical characteristics, such as a reduced cross-talk and good electrical stability, and mechanical characteristics which enable the cable to be easily manufactured, handled and installed.
