Abstract:
1. A method for producing mechanical locking systems in a floor panel using a first tool configuration, the floor panel comprising: wear resistant top surface layer, a core and mechanical locking systems on a first and second edge for horizontal locking of the floor panel with similar other panels, the mechanical locking system comprising: a first pair of locking surfaces in the first edge of a panel and a second pair of locking surfaces in the opposite second edge, the first pair of locking surfaces comprises a first upper edge and a locking element, the second pair of locking surfaces comprises a second upper edge and a locking groove, wherein the method comprises: displacing the floor panel in a feeding direction with its first edge relative to a first tool configuration, the feeding direction having a horizontal plane parallel with the wear resistant top surface layer of the floor panel as the floor panel is displaced in the feeding direction, the first tool configuration comprises a first and second tool body positioned on a same side of a first column having two opposite column sides, the same side facing in a direction parallel with the horizontal plane of the feeding direction, preprocessing at least a part of the wear resistant top surface layer of the floor panel on the first upper edge such that properties of the wear resistant top surface layer are changed; forming by the first and second tool body at least a part of the first upper edge and a part of the locking element; wherein the first tool configuration is a rotating tool configuration comprising the first tool body having a first tool disk and the second tool body having a second tool disk, and the method comprises driving the first and second tool disk with one rotary shaft, the disks being adjustable in relation to each other.
