Abstract

The apparatus for straightening a metal strip includes guide rolls (14, 15; 16, 17) arranged parallel to one another and a straightening roll (18; 19) located in the wedge-contoured gap between the two guide rolls. Through the strip the guide and straightening rolls are in indirect contact with one another in the zone of their mutual tangent surfaces.
