The invention concerns a method for adjusting a flattener under traction and a corresponding device, for providing a metal strip () in particular a cold-rolled steel plate, comprising a cage (), cage posts (), two stacked cassettes () supporting each a plurality of rollers () between which the metal strip () is fed. The invention is characterized in that it consists in measuring a physical quantity representing the angular position of said cassettes () relative to the feeding direction of the said trip ().

Method for adjusting a flattener under traction and corresponding device

A metal measurement plate (), having a size suitable for being placed between the set of upper rolls and the set of lower rolls of the leveler, has positioning means () for positioning it with respect to the rolls in the leveling direction, and strain gauges () for measuring elastic deformations of the plate during clamping on the leveler, said strain gauges being fastened to the plate so as to form several transverse rows of gauges (to) each located vertically in line with one of said rolls, on the opposite face of the plate with respect to said roll.
