Document Type and Number:
WIPO Patent Application WO/2004/082860
Kind Code:
A1
Abstract:
A method and apparatus for stably producing a metallic plate material having no camber or an extremely slight camber. The method and apparatus use a rolling machine for a metallic plate material. The machine has at least work rollers and backup rollers. Force in the rolling direction acting on roll chocks on the work side of and the drive side of the work rollers is measured. A difference in the force, in the rolling direction, between the work side and the drive side is calculated.
