Abstract

Official abstract text for this publication.

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 d 1 wound together in a helix with a pitch p 1 and an outer layer (Ce) of N wires ( 11 ) N varying from 6 to 12, of diameter d 2 , which are wound together in a helix with a pitch p 2 around the inner layer (Ci), wherein said cord has the following characteristics (d 1 , d 2 , p 1 and p 2 are expressed in mm): 0.20<d 1 <0.50; 0.20<d 2 <0.50; p 1 /p 2 ≦1; 5<p 1 <30; 10<p 2 <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.

First claim

Opening claim text (preview).

The invention claimed is: 1. A metal cord having two layers (Ci, Ce) of 3+N construction, rubberized in situ, comprising an inner layer (Ci) formed from three core wires of diameter d 1 wound together in a helix with a pitch p 1 and an outer layer (Ce) of N wires, N varying from 6 to 12, of diameter d 2 , which are wound together in a helix with a pitch p 2 around the inner layer (Ci), wherein said cord is obtained by sheathing the inner layer formed by the three core wires wit…
