Folding device and method for the folding of workpieces

A folding device for processing of a workpiece, the folding device comprising:

• a holding device comprising a support having a support surface that defines a holding plane, the holding device is configured for holding the workpiece in a processing position in the holding plane;
• and
• a folding slide for a folding over of an edge of the workpiece into a folding position,
• wherein the folding slide comprises a first folding surface and a second folding surface,
• wherein 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,
• wherein the first folding surface and the second folding surface are intended for pressing onto the workpiece during the folding over of the edge,
• wherein the folding device further comprises a filling slide that comprises a first surface and a second surface and the filling slide is movable relative to the support to a working position so that the filling slide is in contact with the workpiece during the folding over of the edge, and
• wherein the filling slide in the working position is disposed adjacent to the support such that the first surface lies in the holding plane and the second surface is formed as a pressing-on surface inclined towards the holding plane by an angle γ.
