Apparatus and method for twisting first and second single electrical wires to form a cable pair

An apparatus (100) for twisting first and second single electrical wires (11, 12) to form a cable pair (10), wherein the device (100) comprises a main twisting device (120) and a retwisting device (160) with an stationary retwisting module (170) and a retwisting module (180) that is movable along a linear guide direction;

• wherein each of the retwisting modules (170, 180) comprises a transfer unit (172, 182) for transferring and holding an end of the twisted cable pair (10), wherein the transfer unit (172, 182) comprises a first wire gripper (174, 184) for the first single electrical wire (11) and a second wire gripper (175, 185) for the second single electrical wire (12), wherein a relative distance between the first wire gripper and the second wire gripper can be changed, typically changed programmably, according to a distance (a3) between the ends of the wires (11, 12);
• and
• wherein at least one of the stationary retwisting module (170) and the movable retwisting module (180) is configured for retwisting of the respective held cable pair (10).
