Definitions
- the application device has a height limitation with which the maximum height of the edge protection material above the surface during application to a height less than or equal to the height of the top of the riblet film or to the thickness of the adhesive layer of the riblet film. Foil is limited. By means of a corresponding height limitation, it can already be ensured during the application of the edge protection according to the invention that the edge protection does not protrude beyond the riblet film in the molded state. Furthermore, suction for excess edge protection material can be provided in the application device. By sucking off excess edge protection material, it can be ensured that it does not settle in undesired places and possibly harden there.
- edge protection according to the invention can improve the aerodynamic properties of the transition between the two riblet foils when applied to opposite edges of two adjacent riblet films arranged closely together by opening the gap between the two through the edge protection Riblet film is at least partially filled.
- FIG. 4 shows a second exemplary embodiment of a contamination protection 10 according to the invention for the riblet film 2 from FIG.
- the views in FIGS. 4a, b correspond to those from FIGS. 2a, b.
