Abstract (en)

The method involves pressing the reel (6') into the winding bed (11) with a load roller (7) and supporting it in the winding bed on a cushion of compressed air with a minimum load of 0.5 kN/m during the entire spooling process. The compressed air cushion is controlled depending on the load on the load roller and the load roller is used to determine the diameter of the reel.

Abstract (de)

Es wird ein Verfahren zum Aufwickeln einer Materialbahn zu einer Rolle (6) angegeben, bei dem die Rolle in einem Wickelbett (11) liegt, von einer Belastungswalze (7) in das Wickelbett gedrückt wird und zumindest während eines Teils des Wickelvorgangs durch ein Druckluftpolster (4) im Wickelbett unterstützt wird. Hierbei möchte man die Wickelqualität verbessern können. Dazu drückt die Belastungswalze die Rolle während des gesamten Wickelvorgangs mit einer Mindestbelastung von 0,5 kN/m in das Wickelbett. <IMAGE>
