<p>Stranding apparatus includes input and output nipples (3), (4) longitudinally spaced along the wires (1) etc to be stranded. The nipples (3), (4) allow twisted wires to pass therethrough but inhibit the transfer of torque from one side to the other. One or more rotating stranding heads (5) are provided and the apparatus is periodically adjusted between a first condition in which the stranding heads inpart a twist to the wires, and a second condition in which they allow the wires (1) to pass therethrough substantially unaltered. The apparatus may be adjusted by varying the tension of the wires (1) periodically between a level at which the wires are gripped by the stranding heads, and one at which they slip across untwisted. Additionally or alternatively the stranding heads are moved periodically between an engaged position (11) and a disengaged position (10).</p> |
