Claim:
1. A production plant comprising a bending press having a press beam, at least one bending tool connected to the press beam, and at least one angle-measuring device for determining an angular position of at least one limb of a workpiece formed by a bending operation of the bending press with the bending tool relative to a reference plane of the bending press, wherein the angle-measuring device comprises at least one inclination sensor with a reference plane based on the direction of gravity and contained inside the inclination sensor itself, the inclination sensor having a reference surface, and the inclination sensor is supported by the angle-measuring device so that the inclination sensor is placed with the reference surface lying in direct contact with a surface portion of said at least one of the limbs of the workpiece, wherein the inclination sensor measures an angle between the reference surface and the direction of gravity and thereby determines an angle of inclination of at least one of the limbs of the workpiece relative to the reference plane of the bending press or relative to the reference plane of the inclination sensor.
