Does the number of leveling rolls have a bearing on the quality of results?
The process material is subjected to mechanical alternating bends on the machine. The intensity of the alternating bends is reduced toward the machine outlet. The higher the number of leveling rolls, the greater the number of alternating bends. General speaking: the more alternating bends, the better the leveling result. At least five rolls are required to make any effect at all. However, with five rolls you can achieve only a rough level of planarity. For thin material you tend to need more leveling rolls than for thick material. Experience indicates that at least 11 to 13 rolls are needed on parts leveling machines in order to achieve good tolerances.
