THE INVENTION
The appellants claim a method for eliminating crossbow in a metal strip.
Claim 1 is illustrative:
1. A method of eliminating crossbow in metal strip in a strip processing line,
comprising the steps of:
(a) passing metal strip along said strip processing line through a strip
processing device;
(b) detecting crossbow in said strip; and
(c) immediately upstream of said strip processing device,
eliminating said crossbow by pressing a correcting roller against said strip between
two support rolls to a variable depth determined by a detected degree of crossbow,
and wherein in step (b) the crossbow of the strip is measured and a measured value
of the crossbow is compared with a setpoint value to generate an error signal
determining the depth to which said correcting roller is displaced against said strip
between said support roll thereby eliminating the crossbow in said strip.
