    Abstract: A method for forming of a building panel with a surface including a thermosetting resin such that tension created during curing of the surface is reduced or eliminated. Method for producing a panel with a wood based core and a surface layer including a thermosetting resin wherein the method including: curing and connecting the surface layer to the core while applying heat and pressure in a first main pressing step, thus raising a temperature of the surface layer above an initial temperature; applying a bending force on the panel after the first main pressing step to bend the panel such that an uppermost surface of the panel is convex an a lowermost surface of the panel is concave while the panel is still above the initial temperature; and releasing the bending force such that the panel springs back to an essentially flat shape.

    Abstract: Building panels, especially floor panels, which are provided with a locking system including several separate strip parts connected to the panel edge. A strip part, configured to lock panels horizontally and to be fixed to a panel edge, including a strip body with an inner part configured to be fixed under the panel edge and an outer part configured to extend outside the panel edge, wherein the inner part comprises a fixing element configured to lock the strip part to the panel edge in a horizontal direction, wherein the outer part including a locking protrusion, located above the strip body and configured to lock the strip part to the panel edge vertically and a locking element configured to lock the panels in a horizontal direction, and wherein the inner part includes a cavity formed in the strip body and located between the fixing element and the locking protrusion.
