Abstract: The invention relates to a method for producing a double-flanged seam (1) between an inner component (2) having a wing flange (4) and an outer component (3) having a fold flange (7), comprising at least the following steps: applying an adhesive strip (8) in cold condition to the front edge (12) of the wing flange (4), heating up the adhesive strip (8), gluing the adhesive strip (8) on to one side or both sides of the wing flange (4), applying the inner component (2) to the outer component (3), crimping over the fold flange (7) toward the inner component (2), and heating up at least the double-flanged seam region to cure the adhesive strip (8).

Abstract: The invention relates to a method for producing a double-flanged seam (1) between an inner component (2) having a free edge section (4) and an outer component (3) having a fold edge (7) arranged on an edge section (6), comprising at least the following steps: producing an adhesive structural element (8) with an extension adjusted to a fold gap (11) to be added later on, the extension being shorter than the extension of the fold gap (11), wherein the adhesive structural element (8) has an expandable structural adhesive, applying the adhesive structural element (8) in the cold condition onto one of the components (2, 3) on its side facing the other component (2, 3), crimping over the fold edge (7) toward the inner component (2), wherein the adhesive structural element (8) is bent over with an excess length (13) around the free edge (4) of the inner component (2) at the latest when crimping over the fold edge (7), and heating up at least the area of the double-flanged seam, thus melting the structural adhesiv

Abstract: A method is provided for producing a double-flanged seam between an inner component having a free edge section and an outer component having a fold flange arranged on an edge section, comprising at least the following steps: applying a structural adhesive, which expands under heat, in the form of an adhesive strip to one of the components on the side thereof oriented toward the other component, crimping over the fold flange toward the inner component, thus creating a fold gap, applying a paint coating, at least in the region of the double-flanged seam to one or both of the components, and heating up at least the region of the double-flanged seam, thus melting and expanding the structural adhesive of the adhesive strip, which stretches in the process and thereby partially at least partially covers the paint coating in the region of the double-flanged seam.
