Abstract
A device for straightening a rigid wire delivered in coil form for supplying a metal-working machine is compact and easy to control. The wire is stationary in an axial conduit of a rotor supported on a carriage (B) which is moved axially by means of a first hydraulic jack (13). The rotor carries the wire by stationary guides and a central guide which is moved radially (C) between a centered position and an excentric position by means of a second hydraulic jack (62) while the rotor rotates and the carriage advances. The hydraulic fluid collected at the output (71) of the first jack is transmitted directly to an input (66 or 67) of the second jack (62) so as to actuate it at a speed proportional to that of the first.
