FIELD: physics.
SUBSTANCE: roller for measuring flatness defects of a strip has force transducers built into the lateral surface of the roller with formation of measurement sections and coatings for the force transducers which are flush with the surface of the roller. The coatings are surrounded by a gap for movement with formation of a clearance from the force transducers. The measurement sections are closed by one or more metal films adhesively connected to the surface of the roller. Also the measurement roller has an additional shell.
EFFECT: increased strength and wear-resistance of the measurement roller, prevention of shear deformation in coatings which form measurement sections of the roller.
