Metal cord with a plurality of concentric layers, of the type rubberized in situ, i.e. a cord that is rubberized from the inside, during its actual manufacture, with a rubber known as a filling rubber, in which all or some of the gaps situated between the wires of the cord contain a thermoplastic elastomer of the unsaturated type, particularly an unsaturated thermoplastic stirene (TPS) elastomer such as an SBS, SBBS, SIS or SBIS block copolymer for example. Such a thermoplastic elastomer, used in the molten state, presents no problems of parasitic stickiness if the filling rubber overspills out of the cord following manufacture; its unsaturated and therefore (co)vulcanizable nature makes it extremely compatible with the diene rubber matrices, notably natural rubber matrices as conventionally used as calendering rubber in the metal fabrics intended for reinforcing tires.
