ABSTRACT:
The apparatus comprises an application roller pair which rolls an adhesive tape in a U-shaped manner about the rim of a shaped sheet metal part. The adhesive tape is located initially on a carrier ribbon and is drawn jointly with the former off a storage reel by means of conveyor rollers. After its separation from the carrier tape, the adhesive tape is guided via a loose pre-folding roller to the application roller pair, and the carrier ribbon is led off. The application rollers are pivotable about axes extending parallel with the shafts of the application rollers, and are arranged at the same time resiliently displaceably together with the pre-folding roller in the direction of the shafts. The longitudinal section of the pre-folding roller is concave or V-shaped and is additionally supported, displaceably in the direction of the shafts of the application rollers, by means of softer springs, so that they can follow continuously the edge of the metal sheet and urge the adhesive tape against this edge.
