The invention relates to a method for straightening a metal strip (1) which is guided in the direction of transportation (R) through a straightening machine (2) and is straightened. In the straightening device (2), the metal strip (1) is impinged upon by a straightening force (F) which is applied by a plurality of straightening rollers (3) in the direction (N) which is perpendicular to the surface of the metal strip (1). According to the invention, prior to the metal strip (1) entering into the straightening machine (2), the thickness (d) of the metal strip (1) is determined and the position (a) of the straightening rollers (3) in the direction (N) which is perpendicular to the surface of the metal strip (1) is taken into account according to the determined thickness (d).

The invention relates to a strip sealing gate (1) for sealing a first chamber (2) with a first pressure level (p1) in relation to a second chamber (3) with a second pressure level (p2) that differs from the first, a strip (4), in particular a metal strip, passing through both chambers (2, 3). According to the invention, at least two rollers (5, 6) are provided for sealing the chambers (2, 3), said rollers resting in a sealing manner on either side of the strip (4). The aim of the invention is to improve the sealing action. To achieve this, at least some sections of the circumference of at least one of the rollers (5, 6) are covered with a flexible elastic material (7) and said roller or rollers (5, 6) have an inner core (8) that is covered with a jacket consisting of the flexible elastic material (7). A central region (9) of the inner core (8) has a cylindrical contour (10) and the edge regions (11, 12) of the core (8) are flared.

The invention relates to a belt discharger (1) for sealing a first space (2) with respect to a second space (3), the two spaces (2, 3) being passed by a belt (4), especially a metal belt, the spaces (2, 3) being sealed through provision of at least two rollers (5, 6) which adjoin the belt (4) with sealing on both sides. In order to achieve improved sealing action, the invention envisages that at least one roller (5, 6), in one of its axial end regions (7), has a sealing element (8) which is designed to laterally adjoin the belt edge (9) of the belt (4), with provision of adjustment means (10) with which the roller (5, 6) including sealing element (8) can be positioned in axial direction (a).

The invention relates to a method for tension levelling a cold-rolled strip, whereby the strip passes through a series of break rolls and a series of traction rolls and in the course of its extension is subjected to traction between the two series of rolls. The strip is bent under traction in a series of high-traction rolls, located between the brake roll and the traction roll series, in order to increase the degree of levelling. To achieve this, the series of high-traction rolls between the brake and the traction rolls has at least two traction rolls for generating the strip traction and bending operation.

The invention relates to a sealing gate (1) for strips for sealing a first chamber (2) in relation to a second chamber (3), a strip (4), in particular a metal strip, passing through both chambers (2, 3) and at least one sealing element (5) being provided for sealing the chambers (2, 3). The aim of the invention is to achieve an effective sealing action. To achieve this, the sealing element (5) has at least two gate elements (6, 7, 8, 9) that can be displaced in relation to one another and that have at least one sealing surface (10, 11, 12, 13), which is adapted to the edge contour of the strip (4) to be sealed.

The invention relates to a device (1) for the continuous lengthening of a metal strip (2) by traction, said device comprising, in the strip transporting direction (R), at least three S-roll units (3, 4, 5, 6, 7) each provided with at least two rolls (8, 9 10, 11, 12, 13, 14, 15, 16, 17). According to the invention, the rolls (8, 9, 10, 11, 12, 13, 14, 15, 16, 17) are positioned in such a way that the metal strip (2) is wound round them at a roll periphery angle (a) of more than 180°, and at least the second S-roll unit (4) in the strip transporting direction (R) comprises two rolls (10, 11) with different-sized diameters (D10, D11).
