Abstract (en)

Device for correcting straightening comprising a rotating unit which is suitable to be actuated, so as to perform angular rotations about the advancement axis of an iron rod, by a first motor element (9), so as to arrange itself on different planes in relation to the correction to be performed. Multiple rollers (11a,11b,11c) are mounted, so that they are co-planar, on the rotating unit, and the iron rod is passed between them. A crank system (17a,17b,17c), which can be actuated by a second motor element (16) supported by the rotating unit, is suitable to simultaneously adjust the mutual distance of the rollers (11a,11b,11c) from the iron rod advancement axis. <IMAGE>
