An adhesive web is to be pressed on to the edge of a shaped sheet metal part, so that the web portion on the metal part has a U-shaped cross-section. To this end, the adhesive web is first peeled off a carrier tape and is then folded with the aid of a deflecting and pre-folding roller having a profile whose cross-section is a wide V. The pre-folded web is then folded further continuously in a funnel-shaped pre-folding channel. The sheet metal part whose edge is to be covered is then introduced with that edge, within the reach of the pre-folding channel, into the folded bend of the adhesive web, and both the sheet metal part and the web thereon are conveyed together by a pair of feed and press-on rollers which press the adhesive web on the edge and sides of the sheet metal part. |
