Abstract (en)

[origin: EP1342514A2] Device (1) has angle measurement instrument (10b) that is arranged after the bending tool (2) in the feed direction of a workpiece. The measurement instrument has a measurement value signaler (11) with a measurement element (15) that is brought up to a measurement position on the workpiece. Measurement instrument pivots about an axis perpendicular to the bending plane. Measurement signal is transmitted to a control and evaluation device. An Independent claim is made for a method for controlling a bending tool in which bending of a workpiece is controlled by comparing measured and design angles and adjusting the bending tool accordingly.
