Abstract
A closed loop roller leveler assembly for measuring flatness of a strip, having a roller leveler, a flatness sensor, and at least one arm operatively connected to the flatness sensor to raise and lower the flatness sensor. The flatness sensor has a plurality of sensor rolls, at least one load cell, and at least one laser sensor which is mounted on a positioner which oscillates the laser sensors across a width of the strip.
