  • the mechanical locking system in FR 2 975 717 has a displaceable tongue comprising an outer element which is pushed by a wedge part of a removable inner part of the tongue into a tongue groove, for vertical locking of adjacent edges of two floorboards.
  • a drawback with this known system is that the locking strength is rather low.
  • a further object of embodiments of the present disclosure is to provide building panels, such as floorboards, wall panels or panels for furniture, provided with a locking system that comprises a tongue that improves the vertical locking of the floorboards.
  • Another object of embodiments of the present disclosure is to provide a more efficient production method, which requires less complicated production equipment.
  • the building panels such as floorboards, are provided with a locking system that comprises a displacement groove at a first edge of a first floorboard and a tongue groove at a second edge of a second floorboard.
