A method is provided for manufacturing a multistrand cable having a 1&#xd7;N structure and including a single layer of N strands wound in a helix. Each strand includes an internal layer of M internal threads and an external layer of P external threads. The method includes a step of individually assembling each of the N strands, during which, in chronological order, the M internal threads are wound, the P external threads are wound, and the M internal threads and the P external threads are elongated such that a structural elongation associated with the P external threads of each strand is greater than or equal to 0.05%. The method further includes a step of collectively assembling the N strands, during which the N strands are wound to form the cable.

A bead wire for a tire includes a core, an outer layer, and at least one intermediate layer. The core includes at least one yarn of a multifilament textile fiber embedded in an organic matrix. The outer layer includes an outer-layer metal wire wound around the core. Each intermediate layer includes an intermediate-layer metal wire wound around the core. Each intermediate layer is disposed between the core and the outer layer.
