摘要：A tool configuration incorporating a preprocessing step and a method
incorporating the tool configuration with its preprocessing step, producing an improved
locking system of a floor panel . With the special tool configuration, and the
preprocessing step changing the properties of the surface layer, certain surfaces areprofiled of the joint edge of the floor panel, resulting in decreased tolerances. Anequipment having an upper belt or chain guided in a horizontal direction, by an upperguiding device, and configured to press the floor panel vertically towards the lower chain,decreasing the tolerances of the produced floor panel as well.
