    Abstract: A reinforcement strand (400) comprises a core (403) around which steel filaments (404) are twisted all with the same final lay length and direction. The steel filaments are arranged in an intermediate layer comprising N first steel filaments and an outer layer of 2N steel filaments circumferentially arranged around the intermediate layer. In the intermediate layer filaments will contact one another at a closing lay length that is determined by the number of steel filaments N in the intermediate layer, the diameter of the core and the diameter of the first steel filaments. By choosing the final lay length and direction equal to the between two and six times the closing lay length gaps will form between the intermediate layer filaments. The 2N outer layer filaments are further divided into a group of smaller (408) and a group of larger (406) diameter steel filaments.

    Abstract: A tire having a radial carcass reinforcement, including at least one layer of reinforcing elements, said tire comprising a crown reinforcement, which is itself covered radially with a tread, said tread being joined to two beads via two sidewalls, wherein at least 85% of the reinforcing elements of at least one layer of the carcass reinforcement are non-wrapped metal cords having in what is called the permeability test a flow rate of less than 20 cm3/min, and in that at least 5% of the reinforcing elements of said at least one layer of the carcass reinforcement are cords comprising at least one strand consisting of textile multifilament yarns.

    Abstract: Method of manufacturing a metal cord with three concentric layers (C1, C2, C3), rubberized in situ, of M+N+P construction, comprising a first, internal, layer (C1) consisting of M wires of diameter d1, M varying from 1 to 4, around which there are wound together in a helix, at a pitch p2, in a second, intermediate, layer (C2), N wires of diameter d2, N varying from 3 to 12, around which there are wound together as a helix at a pitch p3, in a third, outer, layer (C3), P wires of diameter d3, P varying from 8 to 20, the said method comprising the following steps which are performed in line: an assembling step by twisting the N wires around the first layer (C1) in order to form, at a point named the “assembling point”, an intermediate cord named a “core strand” of M+N construction; downstream of the assembling point, a sheathing step in which the M+N core strand is sheathed with a rubber composition named “filling rubber” in the uncrosslinked state; an assembling step in which the P wires of the first layer (C3) are twisted around the core strand thus sheathed; a final twist-balancing step. Also disclosed is a device for implementing such a method.
