    Abstract: Method of manufacturing a metal cord with three concentric layers (C1, C2, C3), of the type rubberized in situ, i.e. incorporating a composition made of rubber in the uncrosslinked state referred to as “filling rubber”, the said cable comprising a first, internal, layer or core (C1), 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 second layer 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: a first sheathing step in which the core (C1) is sheathed with the filling rubber; a first assembling step by twisting the N wires of the second layer (C2) around the core (C1) thus sheathed in order to form, at a point named the “assembling point”, an intermediate cord named “core strand” (C1+C2); downstream of the said assembling point, a second sheathing step in which the core strand (C1+C2) is sheathed with the filling rubber; a second assembling step in which the P wires of the third layer (C3) are twisted around the core strand (C1+C2) thus sheathed; a final twist-balancing step.

    Abstract: A wire rope has an independent wire rope core including lubricated individual core wires that are encapsulated in a tubular sheath of elastomeric or polymeric material surrounding the core wires and retaining the lubricant. A plurality of strands are located radially outwardly from and adjacent to the core. Each of the strands include strand wires that are lubricated. The strand wires are encapsulated in a tubular sheath of elastomeric or polymeric material that retain the lubrication for the strand wires. The core and strand encapsulating materials prevent direct metal-to-metal contact between core wires and strand wires, and between strand wires of adjacent strands. The core and strand encapsulating materials are applied in a manner so as to avoid loss of lubricant. Retaining lubrication and preventing direct metal-to-metal contact significantly improves the useful life of the wire rope.
