Abstract (en)

[origin: FR2833868A1] The tube bending machine comprises a bending arm (3) provided with a jaw support (7) which moves horizontally towards the bending head (2). The jaw support is integral with a clamping jaw (8) comprising jaws (9,11) for bending the tube (4) in a clockwise direction and a jaw for bending the tube in an anti-clockwise direction. A bending roller (12), stationary on the bending arm, comprises jaws (13,15) for bending the tube in a clockwise direction and a jaw for bending the tube in an anti-clockwise direction. The jaws are laterally offset relative to each other and on either side the bending head vertical axis. A first gib support (16) comprises jaws (18,19) for the clamped accompaniment of the tube when it is being bent in a clockwise direction and a second gib support (17) comprises a jaw (21) for clamped accompaniment of the tube when bending bent in the anti-clockwise direction.
