<p>J strands form a core. K outer strands are wound around it in a helix with pitch PK, each having a cord with an L wire inner layer of diameter d1, and an M wire outer layer of diameter d2, wound around the inner layer in a helix with pitch p2; with (in mm): 0.10<d1<0.50; 0.10<d2<0.50; 6<p2<30; its inner layer is sheathed with filling rubber; over any length PK of 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.</p> |
