Temper rolling machine of a metal band

A machine for temper rolling a metal band including means for controlling the tension-adjusted running of the band according to a longitudinal direction and along a running plane, at least two temper rolling units placed on both sides of the band and including each an active cylinder and a set of back-up members rotatably mounted on a transversal chassis, around rotational axes parallel to one another and orthogonal to the running direction, and means for controlling the displacement of each temper rolling unit, parallel to itself, between a resting position for which the active cylinder is moved away from the band 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, whereas each active cylinder can be brought into rotation, before application to the band, at an angular speed corresponding substantially to the running speed of the band, wherein each active cylinder is carried, at each of its ends, by a centring journal mounted rotatably around the axis of the cylinder, on a supporting part mounted slidingly on the transversal chassis of the unit parallel to a radial plane running through the axis of said active cylinder, each supporting part of an active cylinder including a portion in the form of a box, a bearing mounted in said box rotatably supporting the corresponding journal of the active cylinder, centred on the radial plane, and an arm mounted to slide on a rail arranged on a guiding foot attached to the transversal chassis;

• wherein the positions with respect to said chassis of both supporting parts may be adjusted by radial sliding for the displacement of the active cylinder, parallel to its axis, between an application position on its back-up members and an away position;
• and wherein each active cylinder may be brought into rotation around its axis by direct application of a rotational torque on one of its centring journals.
