Abstract: The invention relates to a method and a machine for temper rolling a metal band including at least two temper rolling units E, E? each carrying an active cylinder (2) and a set (7, 70) of back-up members mounted rotatably on a transversal chassis (1), and means for displacement vertical of each temper rolling unit (E) between a resting position and a temper rolling position for which the active cylinder is applied to the band while bearing, on the opposite side, on its back-up members (7) whereas each active cylinder (2, 2?) may be brought into rotation around its axis, in its position away from the band, at an angular speed corresponding to the running speed of the band.
