Abstract
A tensionless leveller for levelling a metal strip and having an entry and an exit includes n+1 motorized rolls each having a constant radius R. The leveller also includes a lower superposed cassette supporting at least n/2 of the rolls and an upper superposed cassette supporting at least n/2 of the rolls not supported by the lower superposed cassette. The rolls are offset with respect to one another and are placed alternately above and below a path of the strip. An axis of each of the rolls of the lower cassette is separated from an axis of an immediately successive roll of the upper cassette by a center-to-center spacing E, in which: for k from 2 to 4, R/E=R/E; for k from n−3 to n, R/E=R/Eand R/E<R/E; and for k from 5 to n−1, R/E≦R/E≦R/E, and R/E≧R/E.
