A metal strip leveler (B): the strip has a thickness (e) subject to a stress distribution. The leveler includes a row of upper rolls (. . . ) and a row of lower rolls (. . . ) 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 ([) and two lower rolls ([) 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.

An installation for planishing running metal of strip or plate products includes: a frame in which are disposed a lower planishing cassette and an upper planishing cassette, a lower drive device for driving planishing rollers of the lower cassette in rotation, an upper drive device for driving planishing rollers of the upper cassette in rotation. A displacement device displaces a secured assembly including the lower cassette and lower drive. The displacement device is activated for removal of the lower cassette from the frame toward one side or for insertion of the lower cassette from the one side into the frame. The secured assembly includes a replacement tool coupled to the lower cassette on a second operator side opposite the first motor side in relation to the product running axis. A method associated with the planishing installation is also described.
