RAISED SEAM

摘要

The invention concerns a method for producing a raised seam (1) between an inner component (2), which has a free edge section (4), and an outer component (3), which has a fold edge (7) disposed on an edge section (6), the method involving at least the following steps: producing a structural adhesive element (8) having an extension which is adapted to a subsequent fold gap (11) and is shorter than the extension of the latter, the structural adhesive element (8) comprising an expandable structural adhesive; applying the structural adhesive element (8) in the cold state to one of the components (2, 3) on the side thereof oriented towards the other component (2, 3); folding over the fold edge (7) in the direction towards the inner component (2), the structural adhesive element (8) being bent around the free edge (4) of the inner component (2) with an overlap (13) at the latest when the fold edge (7) is folded over; and heating at least the raised seam region such that the structural adhesive melts and, expanding in all directions, emerges from the fold gap (11) and forms a sealing bead (26, 27).
