Abstract: A coiling device includes a coiler (1) having a coiling mandrel (3) for coiling a metal strip (2) which is fed (x) to the coiler (1), and a coiling swing arm (4) having a front and a rear pressure roller (5, 6) and a deflection plate (7). A swing arm drive (8) lines up the coiling swing arm (4) with the coiling mandrel (3) and is driven away from the coiling mandrel (3). An upper duct flap (9) upstream of the coiler (1) in the feed direction (x) for guiding the metal strip (2). A flap drive (10) for positioning the upper duct flap (9) such that, when the coiling swing arm (4) is lined up with the coiling mandrel (3), the upper duct flap is arranged between the coiling mandrel (3) and the front pressure roller (5) of the coiling swing arm (4) or is arranged upstream of the front pressure roller (5) of the coiling swing arm (4). In the first-mentioned case, the metal strip (2) is deflected around the coiling mandrel (3) only by the rear pressure roller (6) and the deflection plate (7) of the coiling swing arm (4) and, in the last-mentioned case, additionally also by the front pressure roller (5).

Abstract: 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).
