Abstract (en)
[origin: WO2007141273A1] Bending machine (10) and method for shaping metal bars (11) fed from a roll (12). The machine (10) comprises a bending assembly (13) for the metal bars (11), a shearing assembly (14) disposed upstream of the bending assembly (13) to shear the metal bars (11) to size, a first drawing assembly (15) disposed upstream of the shearing assembly (14) to unroll the metal bars (11) from the roll (12) and feed them to the bending assembly (13), and a second drawing assembly (16) disposed between the shearing assembly (14) and the first drawing assembly (15) and provided with gripper members (21, 22, 121, 122). The second drawing assembly (16) comprises selective clamping/unclamping members (23, 123), which intervene on the gripper members (21, 22, 121, 122), to selectively configure the second drawing assembly (16) between a first uninfluential operating condition, in which the gripper members (21, 22, 121, 122) do not interfere with the advance of the metal bars (11), and a second active operating condition, in which the gripper members (21, 22, 121, 122) intervene on the terminal segments of the roll (12) no longer gripped in the first drawing assembly (15) and feed the bending assembly (13).
