Claim:
A multistrand metal cord of K×(L+M) construction, which can notably be used for reinforcing tire belts for industrial vehicles, consisting of K elementary strands assembled in a helix, with a helix pitch P K , each elementary 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 assembled 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; 3<p 2 <10; wherein said inner layer of the elementary strand is sheathed with a rubber composition called a “filling rubber”; over any length of the elementary strand equal to K times 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 elementary strand is between 5 and 40 mg per g of elementary strand.
