Definitions
- the invention relates to a method in the preamble of the first claim specified type.
- the sheets involved are used to prevent crevice corrosion in the flanged seam glued in the seam area. Then a flanged seam is glued on Sealing layer applied, which completely closes the crimping gap on the one hand and on the other hand includes the free sheet edge.
- the second heating preferably takes place by means of a capacitive high-frequency field, in the case of metallic components, the component can serve as an electrode.
- the counter electrode is then positioned over the sealing layer. This can the counter electrode conform to the shape of the entire flanged seam, however it is it is also conceivable to make the electrode shorter and the sealing layer to successively subject the second heat treatment.
- an outer sheet 1 is connected to an inner sheet 2 as an example.
- the outer sheet 1 is flanged by 180 ° in its edge area 3, so that the edge area of the inner sheet is covered.
- an adhesive applied mainly PVC plastisols, epoxy resins, acrylate plastisols or synthetic rubbers in Consideration.
- the sealing layer 8 is applied using an application nozzle 6 the flared seam 4 applied.
- Immediately in this context means that a quick application of the sealing layer 8 is not hindered, but it is ensured that the area to be sealed warms up to the gelation temperature has been.
- the sealing layer 8 is applied to the heated layer Flanged seam 4 a gelatinization of the boundary layer between the sheets 1, 2 and the sealing layer 8.
- the actual pre-gelling of the sealing layer 8 takes place in the capacitive High-frequency field, as shown in Figure 2.
- a counter electrode 7 is used for this, which corresponds in shape to the flanged seam 4 or at least partial areas of it.
- the sheets 1, 2 themselves serve as electrodes.
- the sealing layer 8 is heated by the excitation of the Dipole material present. The heat is thus generated in the sealing material itself, in this process step, the sheets are only removed from the heat conduction Sealing layer warmed.
- the final hardening of the sealing layer takes place in a later process step, for example while passing through an oven.
