Summary:Metal cord (C-1) having two layers (Ci, Ce) of 3+N construction, rubberized in situ, comprising an inner layer (Ci) formed from three core wires (10) of diameter d1 wound together in a helix with a pitch p1 and an outer layer (Ce) of N wires (11) N varying from 6 to 12, of diameter d2, which are wound together in a helix with a pitch p2 around the inner layer (Ci), wherein said cord has the following characteristics (d1, d2, p1 and p2 are expressed in mm): 0.20<d1<0.50; 0.20<d2<0.50; p1/p2 1; 5<p1<30; 10<p2<30; the inner layer is sheathed with a diene rubber composition called a "filling rubber" (12) which, for any length of cord of at least 2 cm, is present in the central channel (13) formed by the three core wires and in each of the gaps lying between the three core wires (10) and the N wires (11) of the outer layer (Ce); and the content of filling rubber in the cord is between 5 and 30 mg per g of cord.
