ABSTRACT:
In an apparatus for straightening metal strip comprising guide rolls arranged parallel to one another a straightening roll is arranged in the gusset space between two guide rolls which has the strip wrapped round it in a form-fitting manner between two lines of contact along which the guide rolls are in indirect contact with the straightening roll. This makes it possible to straighten even high-strength strip without the need to apply tensile loads which exceed the magnitude needed to transport the strip through the apparatus.
