Abstract (en)
Bending device (10) to bend at least a bar (11), for example metal, comprising fixed contrasting members (13), a bending support (15) mounted rotary around the fixed contrasting members (13) both in a clockwise and anti-clockwise direction, and a bending element (16) mounted radially on the bending support (15) in order to rotate therewith, so as to bend the bar (11), in cooperation with the fixed contrasting members (13). The bending support (15) defines a lying plane (P) on which the bar (11) is positioned. The device (10) also comprises movement elements which move the bending element (16) with respect to the bending support (15) between a first operating position, wherein the bending element (16) is at least partly above the lying plane (P), and a second retracted position wherein the bending element (16) is below the lying plane (P).
