METHOD FOR CONTROLLING EDGE TAPER IN METAL ROLLING MILL ABSTRACT OF THE INVENTION A method for controlling edge taper ("feather") in a rolled metal strip utilizes a rolling mill having at least one pair of opposed work rolls through which the strip is passed for thickness reduction. The method first provides that a target rolling pressure is established as a function of the desired maximum amount of edge taper. A target crown for the finished strip is then established and the final work roll crown which will produce the target crown at the target rolling pressure is determined. The work roll crown is then adjusted to the final work roll crown for making the final pass of the strip through the work rolls.
