Abstract

A roll stand has a frame, a pair of small-diameter and substantially parallel working rolls defining a workpiece nip, and respective journal blocks supporting the working rolls in the frame for rotation about substantially parallel axes flanking the nip. These working-roll journal blocks and the respective working rolls can be axially shifted in the frame and the working rolls can be bent positively and negatively, that is respectively convex and concave toward the workpiece. A pair of large-diameter and substantially parallel backup rolls flank and bear toward the nip on the working rolls. Respective journal blocks support the backup rolls in the frame for rotation about substantially parallel axes flanking and generally coplanar with the working-roll axes. A strip is passed repeatedly in a multipass run through the nip generally perpendicular to the plane while the working rolls are pressed against the workpiece to reduce its thickness. The working rolls are axially displaced relative to the workpiece a plurality of times during the run to change the region of contact between the workpiece edges and the working rolls during the run. The working rolls are also bent at least to maintain the workpiece thickness downstream of the nip generally uniform.
