Abstract The method and apparatus of the present invention is a rolling mill having rolls with inverse symmetrical profiles and a method of using the same. An inverse symmetrical profile is a profile in which the right and left sides of a roll, with respect to the roll center line, have the profiles that are described by the same polynomial function but with opposite signs. A family of metal strip profiles can be created by the method and apparatus of the present invention wherein the family of strip profiles created prior to roll shifting are strip profiles expressed by polynomial functions having terms of the nth order, and the family of strip profiles produced by shifting at least one upper roll having an inverse symmetrical profile and at least one lower roll having an inverse symmetrical profile are strip profiles expressed by polynomial functions having terms of the (n-1)th order, where n is preferably 1-5, inclusive.
