Abstract
A method for folding over an edge of a decorative layer, a fold-over system, a method for converting a fold-over system, and an interior trim part. To reduce cycle times and to achieve excellent quality of the produced laminated parts at the same time, a method is provided wherein the fold-over slide for fixing the edge of the decorative layer is cooled by means of an active cooling means. Alternatively or cumulatively, the fold-over slide according to the invention is heated by means of an active heating means. In a preferred embodiment, a heating fluid flows through the fold-over slide when the fold-over slide is already pressing the adhesive into the adhesive joint, such that the hot-melt adhesive is activated. Then, under persistent contact pressure, the fold-over slide is cooled until fixation occurs. Then the fold-over slide is removed, and the carrier part can be exchanged.
