RAISED SEAM

摘要

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 adhesive causing it also to leak from the fold gap (11) in a manner expanding in all directions and forming a sealing bead (26, 27).
