Abstract (en)
A device (1) for bending a blank (2) comprises a support (7), a clamp (3), a mobile bending tool (5) with two arms (53, 53') supported by a structure (51) and a blank handling system. The arms are mobile with respect to the support structure and each other. The blank handling system comprises mechanism (8) for displacing the structure in a direction (X-X') essentially parallel to the immobilized part of the blank and two drive mechanisms (6, 6') able to independently displace each of the arms in a direction (Y-Y') essentially perpendicular to the immobilized part of the blank.
