Abstract
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for producing a foil slitting cut in a foil of a foiled metal sheet. A foil slitting tool is moved along a predetermined path with a tool tip resting on the metal sheet and thereby mechanically produces the foil slitting cut by displacing foil material along the path. The foil slitting cut has at least one acute-angled tooth for forming at least one foil corner detached from the metal sheet.
