Abstract

Die Erfindung betrifft ein Verfahren zum Pulverbeschichten eines Metallbandes (1). Um eine verbesserte Pulverbeschichtung, insbesondere im Falle der Aufbringung von Pulverlack, zu erreichen, ist erfindungsgemäß vorgesehen, dass das auf das Metallband (1) aufzubringende Pulver in einem Pulverdosiersystem (2) gemäß einer gewünschten Auftragsmenge Pulver pro Zeit dosiert wird und dass das von dem Pulverdosiersystem (2) dosierte Pulver zu einem Luftdüsensystem (3) gefördert und von diesem auf das Metallband (1) aufgebracht wird, wobei der zur Auftragung des Pulvers durch das Luftdüsensystem durchgeleitete Luftstrom unabhängig von der Auftragsmenge des Pulvers pro Zeit gewählt bzw. eingestellt wird. Des weiteren betrifft die Erfindung eine Vorrichtung zum Pulverbeschichten eines Metallbandes.

The invention relates to a method for powder coating a metal strip (1). In order to achieve an improved powder coating, in particular in the case of the application of powder coating, it is provided according to the invention that the powder to be applied to the metal strip (1) is metered in a powder metering system (2) according to a desired application rate of powder per time and that of the Pulverdosiersystem (2) metered powder is conveyed to an air nozzle system (3) and applied by this on the metal strip (1), wherein the applied for application of the powder through the air nozzle system air flow is selected or adjusted independently of the order quantity of the powder per time. Furthermore, the invention relates to a device for powder coating a metal strip.
