Abstract: A device for fabricating an insulating material cellular sheath around a conductor. The device has a central guide including a longitudinal passage adapted to receive the conductor. The fabrication device further has a peripheral guide, an internal surface of the peripheral guide and an external surface of the central guide defining a passage adapted to receive the insulating material in a viscous state. The fabrication device further maintains a sleeve separate from the central guide and the peripheral guide. At least a portion of the sleeve is adapted to be placed between the central guide and the peripheral guide and includes an opening that opens onto the central guide and onto the peripheral guide.

Abstract: A flexible coaxial cable includes a shield formed by at least one metal tape provided with a metal coating and wound helically around the insulated core of the cable. The shield is sealed to itself in leakproof manner by the coating which is melted so as to bond directly together the overlapping turns of a single tape or the overlapping turns of two superposed tapes by subjecting the cable provided with the shield to peripheral induction heating.
