<p>The invention relates to a device for spraying a surface of a substrate, wherein the device comprises at least one first spray nozzle for the supply of a fluid to the surface of the substrate to be treated and the first spray nozzle is arranged at a first distance from the substrate, wherein at least one second spray nozzle is arranged at a second distance from the substrate and a ratio of the second distance to the first distance is in a range from 0.1 to 0.8. At most a first volume flow of the fluid can be passed through the at least one first spray nozzle and at most a second volume flow of the fluid can be passed through the at least one second spray nozzle, wherein the ratio of the second volume flow to the first volume flow is in a range from 0.005 to 0.5.</p> |
