Abstract
Building panels 1, 1′ provided with a mechanical locking system including a tongue 30, at first edge 4a of a first building panel 1, cooperating with a tongue groove 20, at a second edge 4a of an adjacent second building panel 1′, for vertical locking of the building panels and a method for producing such building panels 1, 1′. The method includes the step of forming the tongue of material of the first edge. The insertion groove (40) may have a sidewall (60) at a third edge (5a), which is adjacent the first edge (4a), and may be open at a fourth edge (5b), which is opposite the third edge.
Claims9
Method for producing a locking system at edges of building panels, said locking system comprising a tongue at a first edge of a first building panel, cooperating with a tongue groove at a second edge of an adjacent second building panel, for vertical locking of the building panels, wherein the method comprises the steps of:
- forming material of the first edge to obtain at least parts of the outer shape of the tongue;
- forming an insertion groove at the first edge, wherein said insertion groove is sidewardly open and extends in the horizontal direction;
- horizontal direction;
- forming a connection part between a lower part of the tongue and an upper edge of the first edge;
- and
- displacing the tongue at least partly into the insertion groove, and breaking the connection part during the displacement of the tongue.
