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. According to the invention, the driving into rotation of each active cylinder ( 2 ) is determined by direct application of a rotational torque on a journal ( 3 ) attached removably to one end ( 31 ) of the cylinder ( 2 ), whereas the angular speed of the active cylinder ( 2 ) may be slaved to the running speed of the band M, in order to avoid any risk of slipping at contact and, even, during the temper rolling.
