The invention concerns a bending apparatus (20) , which is adapted to bend an edge flange of a workpiece (21/22) , that is of sheet metal and is clamped by a sheet holder (24) in a bed (30) . The bending apparatus (20) comprises at least one prebending tool (31) , which is arranged on a first tool holder (29) and is movable relative to the same by a parallelogram linkage, and at least one final bending tool (27) , which is arranged on a second tool holder (28) . According to the invention, the bending apparatus (20) is arranged in a press (23) , which has a first and a second press unit which are displaceable toward and away from each other, the first tool holder (29) being mounted on the first of said press units together with said bed (30) and the second tool holder being mounted on the second of said press units, and both the prebending tool (31) and the final bending tool (27) being driven by the displacing movement of the second press unit relative to the first press unit. |
