Abstract

Apparatus for intermittently coating a substrate located relative to the device in a transport direction U in movement, comprising a nozzle body with at least two nozzles jaws, wherein a liner sheet is provided with a recess between the nozzles jaws, wherein the recess in the liner film forms a nozzle slot in the nozzle body, and the die slot transverse to the transport direction U of the substrate and parallel to the substrate extend terminates in an exit gap, wherein the exit slit via the nozzle slot in flow communication with an inlet conduit and a nozzle jaw is provided with at least two openings at least that between the inlet channel and the outlet gap in the nozzle slot open out serially and are each sealed with an elastic deformable member sealing fluid to the nozzle slot out, each elastically deformable element on the one hand with the coating material in Dusensc hlitz and on the other hand, is operatively connected to an actuator in the direction of the nozzle slot, whereb...
