Abstract (en)
[origin: WO2010054791A1] Method of manufacturing a metal cord with three concentric layers (C1, C2, C3), that is rubberized in situ, of construction M+N+P, comprising an internal first layer (C1) made up of M filaments of diameter d1, M varying from 1 to 4, around which there are wrapped together in a helix at a pitch p2, as an intermediate second layer (C2), N filaments of diameter d2, N varying from 3 to 12, around which there are wrapped together in a helix at a pitch p3, as an outer third layer (C3), P filaments of diameter d3, P varying from 8 to 20, said method comprising the following steps performed in line: - a step of assembling, by twisting, the N filaments around the first layer (C1), in order to form at a point known as the "assembly point" an intermediate cord known as a "cored strand" of construction M+N; - downstream of the assembly point, a step of jacketing the cored strand M+N with a rubber compound known as "filling rubber", in the non-crosslinked state; - a step of assembling the P filaments of the first layer (C3) by twisting around the cored strand thus jacketed; - a final torsion equalizing step. Device for implementing such a method.
