Abstract
A metal strip leveler (B): the strip has a thickness (e) subject to a stress distribution. The leveler includes a row of upper rolls (1, 3, 5, 7, 9 . . . ) and a row of lower rolls (2, 4, 6, 8, 10 . . . ) having parallel axes, are longitudinally offset in a direction of line of passage (lp) and are offset in height, to define, by vertical imbrication (overlapping) of the rolls, an undulating path of the strip between the rolls. The imbrication occurs because the rows of rolls are interleaved partially to create an undulating path for the strip. At least two upper rolls ([1, 3]; [5, 7]) and two lower rolls ([2, 4]; [6, 8]) are arranged respectively above and below the line of passage, such that they form three vertical imbrication gaps. Those gaps have a profile of non-linear imbrication values (Imbr) that are either convex or concave with respect to a profile of linear imbrication values (Imbr_lin) in the direction of the line of passage.
