Patent ID: 8863490

Claim:
A multistrand metal cord having two layers of J+K construction, which can notably be used for reinforcing tires for industrial vehicles, consisting of a core comprising J strands forming an inner layer, J varying from 1 to 4, around which core are wound, in a helix, with a helix pitch P K of between 20 and 70 mm. K outer strands forming an outer layer around said inner layer, each outer strand: comprising a cord having two layers of L+M construction, rubberized in situ, comprising an inner layer comprised of L wires of diameter d 1 , L varying from 1 to 4, and an outer layer of M wires, M being equal to or greater than 5, of diameter d 2 , which are wound together in a helix with a pitch p 2 around the inner layer; and having the following characteristics (d 1 , d 2 and p 2 being expressed in mm): 0.10<d 1 <0.50; 0.10<d 2 <0.50; 6<p 2 <30; wherein the inner layer of the outer strand is sheathed with a rubber composition called a “filling rubber”; over any length of the outer strand equal to P K , the filling rubber is present in each of the capillaries delimited by the L wires of the inner layer and the M wires of the outer layer, and also, when L is equal to 3 or 4, in the central channel delimited by the L wires of the inner layer; and the amount of filling rubber in said outer strand is between 5 and 40 mg per g of strand.
