THREE-LAYER STEEL CORD THAT IS RUBBERIZED IN SITU AND HAS A 3+M+N STRUCTURE
Abstract:
The invention relates to a steel cord (C-1) with three layers (C1, C2, C3) and a 3+M+N structure, that is rubberized in situ and comprises: a first layer or central layer (C1) formed by two wires (10) of diameter d1 assembled in a helix at a pitch p1; a second layer (C2) formed by M wires (11) of diameter d2, which are wound around the central layer (C1) in a helix at a pitch p2; and a third layer (C3) formed by N wires (12) of diameter d3, which are wound around the second layer in a helix at a pitch p3. The cord is characterised in that it has the following characteristics: (d1, d2, d3, p1, p2 and p3 being expressed in mm): - 0.08 = d1 = 0.5; - 0.08 = d2 = 0.5; - 0.08 = d3 = 0.5; - 3 1 2 3
