Patent ID: 8141403

Claim:
Method for bending an elongated blank, comprising: urging the blank along an axial direction between a movable bending tool and a counter-tool, while the blank is being moved forwards, moving the bending tool from a neutral position, in which the blank is not bent, to a working position, in which the blank is bent to the desired bending centerline radius, the working position being rotated with respect to the neutral position by a given angle of rotation depending on the desired bending centerline radius, and urging the blank between a pair of shoes upstream of the bending tool so as to make the deformation of the blank easier, wherein the step of moving the bending tool from the neutral position to the working position is carried out by controlling at least two degrees of freedom of the movement of the bending tool in a plane defined by the axial direction and by a transverse direction perpendicular to the axial direction.
