Abstract (en)
[origin: US4356716A] A bending machine for flanging sheet metal elements comprises retaining rams for gripping a sheet metal element and at least one drivable bending tool, which is movable about a backing tool that is constituted by an end portion of one retaining ram. To avoid a restriction regarding the path along which the bending tool can be moved, the bending tool is mounted to be movable in two directions, which are approximately at right angles to each other, and separate drive means are provided for moving the bending tools in said two directions, respectively.
