Abstract (en)
A device for the measurement of an angle of bending of an edge (8) of a polygonal sheet of metal (7), particularly for a machine for programmable bending on all the sides of the sheet (7), comprises actuators (39) apt to bring a bending blade (3, 4), without thrust, against the bent edge (8) and detectors (36, 37, 38) apt to measure the angle of rotation of the blade (3, 4). The detectors (36, 37, 38), in their turn, are operationally connected to correctors (15, 53; 18; 54) of the angle of bending of the edge (8). <IMAGE>
