The invention relates to a bending device (1) for forming a workpiece (4), having two pressure beams and bending tools (2, 3) mounted thereon, having a measuring device (9, 10) for determining a bending angle (7, 8) for the workpiece (4) with respect to a bending axis (6), said measuring device comprising a lighting device (15) for generating a light line (17) on the workpiece (4) and a camera (21) for capturing an image of the light line (17). The camera (21) and a first exit opening (14) of the lighting device (15) are spaced from one another in the direction parallel to the bending axis (6). The bending angle (7, 8) can be determined using an image recognition program, from a change in the image of the light line (17) in images from the camera (21). The lighting device (15) comprises a second exit opening (19) for producing a second light line, wherein the first exit opening (14) and the second exit opening (19) of the lighting device (15) are spaced from one another in the direction parallel to the bending axis (6), and the camera (21) is arranged between the first exit opening (14) and the second exit opening (19).
