The operation of a roll straightener is quite straightforward yet highly effective. The machine typically consists of multiple rollers arranged in pairs, each set at a specific angle. When the metal strip is fed into the machine, it is subjected to a force that compresses the material as it moves between the rollers. The first pair of rollers applies a downward force, while the subsequent pairs assist in aligning the material progressively. This series of adjustments helps correct imperfections in the metal's shape. The precision of this process is crucial, allowing for minimal deviation from desired specifications.
