Abstract
Means and method for cold rolling metal strip characterized by edge drop. The invention contemplates the use in a cold rolling mill of at least one roll having a base profile provided with a flared component adjacent to at least one end of the roll. The base profile can be crowned, cylindrical, partly crowned and partly cylindrical, or partly cylindrical and partly tapered. The roll or rolls can be work rolls, intermediate rolls or the like. Rolls provided with a flared component at one end only can be arranged in skew-symmetry and shifted independently in an axial direction to adjust the work roll gap profile. The roll or rolls of the present invention and the method employing them achieve uniform elongation of the metal strip, minimizing quarter buckle. The at least one flared portion can be truncated at a point adjacent to the edge of the strip to be rolled.
