Abstract
A tool configuration 68, 68′ incorporating a preprocessing step 67, 67′ and a method incorporating the tool configuration with its preprocessing step, producing an improved locking system of a floor panel 1, 1′. With the special tool configuration, and the preprocessing step changing the properties of the surface layer, certain surfaces are profiled of the joint edge of the floor panel, resulting in decreased tolerances. An equipment having an upper belt or chain guided in a horizontal direction, by an upper guiding device, and configured to press the floor panel vertically towards the lower chain, decreasing the tolerances of the produced floor panel as well.
Claims4
A method for producing mechanical locking systems in a floor panel using a first tool configuration, the floor panel comprising:
- a 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 first tool configuration comprises a first tool body and a second tool body positioned on a same side of a first column having two opposite column sides,
- forming by the first and second tool body at least a part of the first pair of locking surfaces
- 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 comprising driving the first and second tool disk with one rotary shaft, the disks being adjustable in relation to each other.
