Abstract
A system and method for affecting the crossbow in a metal sheet in continuous coating process. The system comprises strip distance sensors for determining distances to the metal sheet. A controller is configured to adjust the position of the correcting roll, based on the strip distances, to affect the crossbow in the sheet to help control the thickness of the coating on the sheet. The system may comprise a crossbow model to help determine the new correcting roll position. The distances determined by the strip distance sensors may be also be used to adjust the position of the air knives.
