Abstract
Building panels, especially floor panels are shown, which are provided with a locking system that is configured to lock the adjacent edges by angling and that have a tongue and a strip on the same edge, and a method to divide a board and produce such building panels. A method for dividing a floor element, into a first floor panel and a second floor panel, said floor element including a core provided with a decorative surface layer and a balancing layer, wherein the method includes the step of forming, through the balancing layer or the decorative surface layer, a second groove by displacing the floor element past a fixed tool.

1-17. (canceled)
Building panels, comprising a surface and a core, provided with a locking system for vertical and horizontal locking of a first edge of a first building panel to an adjacent second edge of a second building panel, wherein upper parts of the first and the second edge in a locked position together define a vertical plane perpendicular to a horizontal plane, which is parallel to the surface, said locking system being configured to enable assembling of the first and the second edge by angling the first and the second building panel relative each other, wherein the locking system comprises a tongue, made in one piece with said core, and a tongue groove configured to cooperate for vertical locking, and wherein the first edge comprises a strip, made in one piece with the core, which is provided with a locking element, which is configured to cooperate for horizontal locking with a downwardly open locking groove formed in the second edge,
- wherein:
- the tongue, which is provided in the first edge, is configured to cooperate with a lower lip of the tongue groove, which is provided at the second edge, at lower vertical locking surfaces,
- the locking element and the locking groove are configured to cooperate at horizontal locking surfaces,
- the tongue protrudes outwardly beyond the vertical plane,
- the tongue groove comprises an upper lip, and
- a horizontal extension of the lower lip, in relation to the upper lip, is smaller than a horizontal extension of the tongue.
