Abstract (en)
Specifically conceived for hardened wires, which up to now require an inverse torsion during the forming of the roll designed to compensate the torsion generated during the unwinding process, it is structured around a fixed platform (5), fitted with an ample central circular hole (6), under which is installed a movable platform (7) capable of rotating freely over the fixed platform (5), facing the hole (6), over the movable platform (7) being mounted a pair of wheels (11) and (12) which press and guide the outgoing wire (18) and are forced to rotate as a result of the longitudinal movement of the wire, one of said wheels (11) transmitting its rotation to a pinion (15) that meshes onto a circumferential rack (16) in the fixed platform (5), so that the longitudinal movement of the wire (18) causes the movable platform (7) to rotate, thus generating a torsion effect on the wire (18) contrary to the natural torsion that occurs during the unwinding process. <IMAGE>
