Abstract
The invention relates to a coating tool for applying a fluid film onto a substrate, wherein disposed upstream of a slot nozzle () for producing a fluid film, said nozzle extending substantially across the entirety of a first width (B) of the coating tool in unbroken fashion, is a distribution space () for distributing the fluid over a second width (B) of the slot nozzle (), wherein at least one channel () for feeding fluid is provided upstream of the distribution space (), said channel having a third width (B), and wherein the third width (B) is smaller than the second width (B). To avoid an uneven throughput of material across the width of the slot, it is proposed according to the invention that a plurality of feed channels () be disposed in the distribution space (), said channels having a cross sectional area that increases in the direction of flow (S).
