1. An improved straightener for straightening coil steel and other metals, comprising:
an upper bank of upper work rollers and a lower bank of lower work rollers, each work roller being rotatable about a respective axis of rotation, and wherein material to be straightened progresses through the upper and lower banks of the work rollers;
a set of backup rollers rotatable about two separate axes of rotation in contact with each work roller to reduce deformation of the work rollers during the straightening of the material;
wherein the backup rollers are supported on backup roller plates, and wherein the backup rollers are independently adjusted by moving the backup rollers toward and away from the backup roller plates to achieve a desired degree of contact between the backup rollers and the work rollers;
