Abstract
A sheet-metal workpiece is clamped in a bending press with its one side lying on a pair of bending beams spaced apart in a transport direction and with a bending roller pressing in a bending direction transverse to the transport direction against the other side of the workpiece between the beams. A first feeler roller is pressed against the one side of the workpiece at the first location opposite the bending roller with a force sufficient to relieve substantially all of the elastic deformation in the workpiece. The workpiece is contacted to each side of the first feeler roller with second and third feeler rollers spaced apart in the transport direction and the spacing between the first feeler roller and the second and third feeler rollers in the bending direction is then measured to ascertain the permanent bend (plastic deformation) of the workpiece.
