Multi-strand cable of 1xn structure for protective reinforcement of a tire

A method for manufacturing a multistrand cable having a 1×N structure and including a single layer of N strands wound in a helix, in which each strand includes an internal layer of M internal threads wound in a helix and an external layer of P external threads wound in a helix around the internal layer, the method comprising steps of:

• individually assembling each of the N strands by twisting, during which, in chronological order:
• the M internal threads are wound in a helix to form the internal layer,
• the P external threads are wound in a helix around the internal layer, and
• the M internal threads and the P external threads are elongated such that a structural elongation (Asp) associated with the P external threads of each strand is greater than or equal to 0.05%;
• and
• collectively assembling the N strands by twisting, during which the N strands are wound in a helix to form the cable.

A strand comprising:

• an internal layer of M internal threads wound in a helix;
• and
• an external layer of P external threads wound in a helix around the internal layer,
• wherein a structural elongation (Asp) associated with the P external threads is greater than or equal to 0.05%.

A multistrand cable having a 1×N structure, the cable comprising a single layer of N strands wound in a helix, wherein:

• each strand includes an internal layer of M internal threads wound in a helix and an external layer of P external threads wound in a helix around the internal layer, and
• the cable is produced by a method that includes steps of:
• individually assembling each of the N strands by twisting, during which, in chronological order:
• the M internal threads are wound in a helix to form the internal layer,
• the P external threads are wound in a helix around the internal layer, and
• the M internal threads and the P external threads are elongated such that a structural elongation (Asp) associated with the P external threads of each strand is greater than or equal to 0.05%, and
• collectively assembling the N strands by twisting, during which the N strands are wound in a helix to form the cable.
