A system for supplying metal wire to a machine by a wire supply device. The wire having a desired tension detected by a tension sensor. The supply device has at least one rotary member driven by an actuator thereof on which the metal wire is wound for a fraction of rotation or several rotations and adapted to supply the wire to the machine with predefined tension under the action of a control unit. The system has a detector, for detecting at least one wire physical characteristic, downstream of the supply device and connected to the control unit to provide to the latter the data regarding each detected physical characteristic. The control unit intervening on the rotary member for adjusting the wire tension for maintaining, at least approximately around a reference value, the characteristic of the wire controlled. The latter is at least one dimensional and/or electrical characteristic. |
