Automatic machine for bending electro-welded meshes formed with longitudinal and transversal wires (1) having different lengths and/or different pitches, the machine being provided with a plurality of bending pins (2, 2-1, 2-2), operated in a vertical direction, said bending pins being reciprocally spaced by a length equal to the pitch of the mesh to be bent, and with a plurality of bending arms (3, 4, 4-1), driven with a composite motion to bend the wires around the bending pins, said bending unit (U) being mounted on a structure (10) of the machine and being mobile in a direction transversal to the direction of movement of the mesh (R), said bending unit (U) being also rotating in the two directions around its own vertical axis (W). The bending pins (2, 2-1, 2-2) are driven by respective actuators (8) contained in the bending unit (U), which are powered selectively and independently of one another according to a prearranged program by a machine control unit, and the bending arms (3, 4, 4-1 ) are connected to the bending unit (U) through an articulated kinematic mechanism (11 -13, 16-19) and are driven selectively and independently of one another by the program of the control unit, in a coordinated manner with the corresponding bending pins. |
