J strands form a core. K outer strands are wound around it in a helix with pitch P, each having a cord with an L wire inner layer of diameter d, and an M wire outer layer of diameter d, wound around the inner layer in a helix with pitch p; with (in mm): 0.10&#x3c;d&#x3c;0.50; 0.10&#x3c;d&#x3c;0.50; 6&#x3c;p&#x3c;30; its inner layer is sheathed with filling rubber; over any length Pof the outer strand, filling rubber is in each of the capillaries delimited by L wires of the inner layer and M wires of the outer layer, and also, when L is equal to 3 or 4, in the central channel delimited by L wires of the inner layer. Filling rubber in said outer strand is 5 to 40 mg per g of strand.

Multi-strand cord in which the basic strands are dual layer cords, rubberized in situ

Metal cord of K&#xd7;(L+M) construction. K elementary strands assembled in a helix, with pitch P, each having a cord with L wire inner layer of diameter d, and M wire outer layer of diameter d, in a helix with pitch paround the inner layer; with (in mm): 0.10&#x3c;d&#x3c;0.50; 0.10&#x3c;d&#x3c;0.50; 3&#x3c;p&#x3c;10; inner layer is sheathed with filling rubber; over a K times Plength of the elementary strand, filling rubber is 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. The amount of filling rubber in said elementary strand is 5 to 40 mg per g of elementary strand.
