1 , 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 d
2 , N varying from 3 to 12, around which there are wrapped together in a helix at a pitch p
3 , as an outer third layer (C3), P filaments of diameter d
3 , 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.

摘要： The proposal is for a wire filament for reinforcing rubber or plastic items, especially pneumatic tyres, which is spiral in shape and exhibits no residual elastic torsional stresses. A wire filament (8) of the invention is produced by twisting drawn straight wire filaments (2) in the plastic deformation region followed by reversal, two wire filaments being put together and secured at the latest before reversal. Advantageously, at least two wire filaments (2) are brought together by means of a perforated plate (30), twisted around each other in a false twister (20) and plastically deformed and then reversed in a further false twister (40).
