Abstract
A metal strip is gripped by an upstream set of infeed tension rollers and, downstream therefrom in a strip-travel direction, by a downstream set of outfeed tension rollers. These tension rollers are rotated so as to tension the strip between the upstream and downstream sets and move the strip downstream in the strip-travel direction. Between the sets the strip first passes around individually supported relatively rotatable stretch rollers to increase a plastic stretch ratio of the strip, and then through a plurality of straightening rollers to reduce curvature and residual tension of the strip and also to increase the plastic stretch ratio of the strip.
