  • WO 99/03634 discloses a method and apparatus for welding interconnecting overlapping metal parts.
  • a resistance welding process is proposed for weld joining sheets with one end portion of a sheet folded around the other sheet.
  • In the area of the folding machine is at least one welding head, including an electrode with welding tip.
  • one of the sheets has a kind of hump.
  • the connection is now made by a force is exerted on the fold by the welding head, so that the fold between the electrode and a pad is fixed. Subsequently, a pulsating welding current is generated, which connects the two sheets together.
  • EP 1 038 627 B1 has disclosed a method and a device for producing a projection welding connection between sheet metal parts.
  • a hump of triangular cross-section is preformed.
  • the plates are superimposed so that they overlap.
  • a fold is created.
  • the welding together of the plates takes place at the location of the hump with a surge of a short Duration, wherein the current is supplied from the side of the printing unit to the top plate and derived from the underlying plate.
  • DE 199 27 208 B4 discloses a method and a device for edge-side joining of sheets, especially of body panels in the automotive industry, wherein the edge of an outer panel is folded over the edge of an inner panel, the edges are pressed together and before folding the edge of at least one of Sheets is provided with embossed protrusions.
  • the projections are connected during compression by a arranged on the flared cheek by projection welding with the other sheet.
  • the invention is, starting from DE 199 27 208 B4, based on the object to provide an alternative structural design of a folding and joining machine, which nevertheless allows a simplified connection of the same in the region of the fold with optimal handling of the sheets within the device.
