During stabilization of a metal band (1) on a roller path (2), the band (1) is to be only minimally cooled via the stabilisation. A device for that includes multiple protective runners (3), each oriented in the conveyor direction (R), for guiding the band (1), wherein the protective runners (3) are arranged above the roller path (2) and the protective runners (3) are at a distance from one another in a width direction (B) of the band (1). Multiple rows (4) of nozzles are arranged in the conveyor direction (R) or in the width direction (B) of the band. Each row (4) of nozzles includes multiple nozzles (5). The nozzles (5) are set back in relation to an underside of the protective runners (3), such that an arched band (1) cannot come into contact with the nozzles (5). A compressed air supply (6) and a network of tubes or pipelines (7) supply the nozzles (5) with compressed air, wherein the nozzles (5) apply compressed air to the upper side of the band (1) in order to stabilize the movement of the band (1) on the roller path (2).

A roll feeder is usable to intermittently feed a coiled material. The roll feeder includes a paired first roll and second roll, a meandering detector, a pressing component, and a controller. The paired first roll and second roll are disposed so as to clamp the coiled material. The paired first roll and second roll are configured to feed the coiled material in a conveyance direction. The meandering detector is configured to detect meandering of the coiled material from a specific conveyance position in a width direction perpendicular to the conveyance direction of the coiled material. The pressing component is configured to press the first roll against the coiled material being conveyed. The controller is configured to control the pressing component so as to correct the meandering based on detection by the meandering detector.

This gate device is provided with a guide unit having a guide section that is disposed at the downstream side of pinch rollers at a path line along which a metal sheet is conveyed, opens/closes a coil-up line that is curved from the path line, and guides the upwards-facing surface side of the metal sheet led in to the coil-up line. A configuration is adopted such that the guide unit has a main body frame and a liner that is attached to the main body frame, forms at least a portion of the second guide surface that guides the metal sheet, has a lower coefficient of friction than the main body frame, and has a lower hardness than that of the metal sheet.

A strip deflector has a base body formed with a tip, a compressed-air chamber, and a nozzle for emitting compressed air. A compressed-air source in flow communication with the compressed-air chamber feeds compressed air to the compressed-air chamber and the nozzle. This nozzle has a first nozzle subpassage in flow communication with the compressed-air chamber and a second nozzle subpassage downstream of the first nozzle subpassage in a flow direction. The first nozzle subpassage is formed by a flank closer to the tip of the base body and an opposite flank remote from the tip of the base body, and, at a transition from the first nozzle subpassage to the second nozzle subpassage, the flank closer to the tip of the base body is bent away toward the tip of the base body so as to form a first separation edge.

A method and a device for guiding and centering a metallic rolling stock in a rolling mill having at least one assembly that is arranged in a rolling line and at least one rolling mill stand for shaping the rolling stock are disclosed. The method includes the use of lateral guide means, which exert a lateral force onto the moving rolling stock at different locations of the rolling line, wherein the method further includes the process of centering the inflow of the rolling stock ahead of a first assembly and/or ahead of a first rolling mill stand of the rolling mill using first lateral guide means and the process of aligning rolling stock downstream transversely to the rolling line using second lateral guide means, wherein the process of centering the inflow includes a funnel-shaped, flat guiding of the rolling stock and a point-shaped guiding of the rolling stock.

A device for ascertaining the lateral strip contour and/or the position of the strip edges of a metal strip. It includes at least one sensing element for ascertaining suitable measurement data. The sensing element is integrated into a lateral guide together with a main part module of the metal strip conveying device. The lateral guide includes at least one wear element which is arranged in the lateral guide and which comprises a wear element adjusting device that can be rotated about a rotational axis substantially perpendicular to a guide plane of the lateral guide. The wear element together with the wear element adjusting device is designed as a sensing element. In an operating method, at least one sensing element is brought into contact with a lateral edge at a starting time, and suitable measurement data is ascertained using the sensing element while the metal strip runs past the sensing element.
