A metal wire feeder device including a body presenting a wire braking member, one or more pulleys driven by respective motors about which the wire is wound, the wire before reaching a processing machine passing through a compensator member and a tension sensor, an electronic control unit able to continuously measure the tension value and make it uniform at a predetermined value by acting on a first regulator loop operating on the motors and a second regulator loop operating on the compensator member. The electronic control unit operates automatically in making the tension uniform at the predetermined value, on the basis of the fed wire quantity or of the wire feed velocity. |
