A method is provided for manufacturing a multistrand cable having a 1N 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.
