Definitions

  • the invention relates to a nozzle device for dispensing a viscous, in particular highly viscous, application medium in the form of at least one jet or at least two jets onto a component, preferably for the surrounding application of the application medium to a fold, an edge or a transition seam of the component.

  • a robot program is usually created in such a way that the lower edge of the spray jet emitted from the nozzle is applied a few millimeters below the standing seam and thus past the standing seam ("shot past") becomes.
  • the PVC material that is applied to one side of the standing seam wraps itself around the seam edge to a certain extent and thus seals the lower, corrosion-prone side of the standing seam.
  • the requirements for a conventional PVC seam are usually 15 mm to 25 mm seam width and 1.5 mm to 2.5 mm seam height. So that this can be achieved with a structurally limited nozzle, the slot opening of the conventional flat jet nozzle is convex so that the jet width of the spray jet increases towards the standing seam and thus towards the delivery side.
  • a particular disadvantage of the prior art described above is that part of the released PVC material is "shot past" the standing seam as a result of the process. This has the consequence that the robot guiding the flat jet nozzle and / or the application cell in which the method is carried out is soiled, and thus an increased cleaning effort arises.
