<p>The method for making reinforcements for reinforced concrete provides to feed a metal wire (2) through unwinding from a reel (3), according to a longitudinal feed axis (A), through a folding unit (5) provided with a central mandrel (6) and with an eccentric folding pin (7) having axis substantially parallel and cooperating for forming a succession of folding of metal wire (2), each folding being localized on a respective folding plane defined between a couple of tracts of wire (2), substantially concurrent to a respective folding vertex (V). One performs a first folding of the wire (2) on a first folding plane and then the feed of the wire (2) according to the longitudinal feed axis (A) of a first tract substantially corresponding to a first side of the reinforcement in formation. Then one performs the axial rotation of the metal wire (2) according to the longitudinal feed axis (A) and then a second folding in sequence to the first one, the second folding resulting localized on a respective second folding plane rotated with respect to the folding plane of the first folding.</p> |
