Method of fabricating bunch of electrical conductors of different lengths for lift systems

摘要

The method involves a first phase in which the longest conductor of the bunch (11) is wound on the rotatable drum (23), having helicoidal slots (25) formed in it into which the conductors are placed. After the first conductor has been wound onto the drum the other conductors are successively wound in length order, side by side, into the slot (25) occupied by the first conductor. The method also involves a second phase of the wire bunch assembly, during which the bunch (11) of conductors is unwound from the drum (23), and fastened together during the unwinding process and then rewound onto a reception support (32).
