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.
