The folding slide at least includes, but is not limited to a first folding surface and a second folding surface. The first folding surface with the second folding surface forms an angle α, the first folding surface with the holding plane forms an angle β1 and the second folding surface with the holding plane forms an angle β2 and the first folding surface and the second folding surface are intended for pressing onto the workpiece during the folding over of an edge.
