Abstract
An apparatus for manufacturing a metal strip (1) includes a number of rolls (2, 3, 4, 5) over which the metal strip (1) is guided in a transporting direction under a strip tension that insures that the strip is flat to a large extent at least between two rolls (2, 3) and a light source (6) operable for illuminating an area of the metal strip (1) as it moves in the transporting direction. Two cameras (7, 8), which are located in a region of the light source (6) at a distance from each other, are operable for photographing the area of the metal strip (1) illuminated by the light source from two different directions.
