Leveling with Roller Levelers

The topic of sheet leveling is more current than ever. Leveling improves the quality of sheet metal processing. The improved tolerances in the flatness of sheet metal parts and coils are obvious. Less obvious are the favourable distribution of residual stresses in the material, which stabilizes the material for the subsequent processes like folding, bending and roll forming. To shed light on the subject and explain what happens during the leveling process on roller levelers give the authors following informations: Priciples of material science, Tension and compression, Bending, Principles of leveling, Roller levelers, Basic design of the leveling unit, Drive system, Leveling performance diagram, Machine setting values, Flatness defects and their correction, Roller levelers for strips, Roller levelers for parts.
