Abstract
Floor panels are shown, which are provided with a mechanical locking system including tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other and configured such that the protrusions can obtain a vertically unlocked position where they match the cavities and a vertically locked position where the protrusions overlap each other.
Claims20
A method to produce protrusions and cavities located after each other along an edge of a floor panel with a rotating tool having a cutter, wherein the cutter rotates along an axis of rotation, wherein the method comprises:
- a) bringing an edge of the floor panel in contact with the tool;
- and
- b) displacing the edge of the panel in relation to the tool essentially parallel with the axis of rotation, the displacing occurring while the edge is in contact with the cutter of the tool and while the protrusions and cavities located after each other along the edge are formed,
- wherein the floor panel position is synchronized accurately with the tool position and the tool rotational speed.
A method to produce protrusions and cavities located after each other along an edge of a floor panel with a rotating tool having an axis of rotation wherein the method comprises the step of:
- a) bringing an edge of the floor panel in contact with the tool;
- and
- b) displacing the edge of the panel in relation to the tool essentially parallel with the axis of rotation,
- wherein the tool is a screw shaped cutter,
- wherein the floor panel position is synchronized accurately with the tool position and the tool rotational speed.
