Abstract
A rolling mill arrangement having at least one roll carrying a sleeve forming a cavity with the roll body near the two opposed ends of the roll. Pressurized fluid is regulated in these cavities to counteract 'edge drop' which occurs at the edges of a product under the conventional procedures for controlling the mill for effecting control of the edge thickness of the strip when reducing the product along its width.
