Abstract

Device for improving the planarity of a steel strip rolled in a roll stand comprises planarity measuring rollers (PMR1, PMR2) and a tension leveling machine (STR) connected to the roll stand (WW). Preferred Features: A first planarity measuring roller is arranged between the roll stand and the tension leveling machine, and a second planarity measuring roller is arranged after the tension leveling machine.
