Curtain coating

Curtain coating of lacquer with curtain coaters. The lacquer is pumped out of a container into a coating head with adjustable coating slits/lips from where it is discharged (mostly under high pressure) and as such forms a constantly flowing curtain of lacquer, the excess of which is caught in a channel and fed back into the lacquer container. The item to be worked on is carried through the flowing curtain of lacquer by means of a suspended conveyor belt. Uniform amounts to be applied of 60 - 300g/m² are obtained
