Abstract
A bending tool () for bending workpieces, especially plate and sheet metal blanks includes at least one bending element () positioned on one side of a workpiece as well as a retainer device with clamping elements () on opposite sides of the workpiece. For bending the workpiece, the retainer is moved, together with the workpiece clamped on it, relative to a bending element (). In the process, the retainer device with the workpiece and the bending element () move relative to each other in a bending stroke which contains a component in the bending-stroke direction as well as a component in the transverse direction of the bending stroke. The direction of the bending stroke is controlled by at least one control element associated with the bending element () as well as at least one guide element associated with the equal-sided clamping element (). The last-mentioned guide element or elements can move in the bending-stroke direction () relative to the first-mentioned control element or elements ().
