Abstract
An elongated bending beam for a swivel bending machine has an approximately C-shaped beam cross section and two bending tools, which are opposite one another relative to a preferably horizontal central plane, and which run facing one another in the longitudinal direction of the bending beam, between which a workpiece portion of a workpiece to be bent can be introduced. An angle-measuring system for contactlessly measuring a bending angle is arranged inside the C-shape beam cross section, with which a bending angle can be measured relative to a reference plane at a workpiece section bent by one of the bending tools. The angle-measuring system also includes a first angle-measuring unit arranged below the central plane and having a first measuring region positioned substantially above the central plane, and a second angle-measuring unit arranged above the central plane and having a second measuring region positioned substantially below the central plane.
