Abstract: The machine for cambering, shaping, bending or curving a bar along a bending axis includes an arm, a bending shank supported by the arm, a bending head including a bending lug that is rotatable relative to the bending axis, and a feeding station for moving the bar along an axis of travel and across the bending shank. The bending head also includes: a first connecting rod supporting the bending lug and having a head, a second connecting rod having a head, the heads being coupled so as to rotate relative to a hinge axis perpendicular to the axis of travel, a first driver for translating a leg of the first connecting rod along an axis parallel to the axis of travel, and a second driver for translating a leg the second connecting rod along an axis parallel to the axis of travel.
