A coiling device that includes a coiler () having a coiling mandrel () for coiling a metal strip, and a coiling swing arm () having front and a rear pressure rollers () and a deflection plate (). A swing arm drive () lines up the coiling swing arm () with the coiling mandrel () and is driven away from the coiling mandrel (). An upper duct flap () upstream of the coiler () in the feed direction (x) guides the metal strip (). A flap drive () positions the upper duct flap () such that, when the coiling swing arm () is lined up with the coiling mandrel (), the upper duct flap is arranged between the coiling mandrel () and the front pressure roller () of the coiling swing arm () or is arranged upstream of the front pressure roller () of the coiling swing arm ().

Coiling device for a large range of metal strip thicknesses

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

Method and device for stabilizing a movement of a rolled metal band on a roller table

A reel for winding metal strip, in particular rolled hot strip, having a mandrel shaft (), which has a first shaft end piece (), which is rotably mounted by means of at least one bearing () provided in the machine frame () of the reel, a clamping device () arranged between the at least one bearing () and the mandrel shaft (), such that, in a clamped operating state, a frictional connection can be produced between the at least one bearing () and the mandrel shaft ().
