A metal wire feeder device (1) comprising a body (2) presenting a wire braking member (12) one or more pulleys (14 15) driven by respective motors (16 17) about which the wire is wound the wire before reaching a processing machine passing through a compensator member (20) and a tension sensor (25) an electronic control unit (18) being present able to continuously measure said tension value and make it uniform at a predetermined value by acting on a first regulator loop operating on the motors (16 17) and a second regulator loop operating on the compensator member (20). Said electronic control unit (18) operates automatically in making said tension uniform at the predetermined value on the basis of the fed wire quantity or of the wire feed velocity. |
