  • a slot nozzle 18 can be seen, from which individual spray curtains can emerge.
  • the spray curtains hit a material web 22, the direction of movement of which is symbolized by an arrow 23.
  • the spray veils produce individual strip-shaped application patterns 24 1 ', 24 2 ' on the material web 22 which have a periodically variable width and limited length.
  • the variable width is generated by a variable width of the surface grooves 27 ′ of the roller slide 13.
  • the slot nozzle 18 contains a comb plate, which produces individual threads running perpendicular to the direction of movement of the material web 22, but which can flow together to form closed spray veils after the outlet.
  • the roller slide 13 has on its cylindrical surface a plurality of two surface grooves 27 'with variable width and limited circumferential length.
