Abstract

Floor panels are shown, which are provided with a mechanical locking system comprising 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.

First claim

The invention claimed is:

1. A tool configured to produce protrusions and cavities located after each other along an edge of a floor panel, wherein the tool is a screw shaped cutter with an axis of rotation parallel with the edge of the floor panel, wherein the tool comprises double screw rows of teeth, and wherein the double screw rows of teeth include teeth which are offset in a rotational direction of the tool and which are formed as a single monolithic piece of material.

2. The tool as claimed in claim 1 , wherein a cutting diameter of the tool is smaller on an entrance side than on an opposite exit side.

3. The tool as claimed in claim 1 , wherein a pitch of the tool defines the intermediate distance of the cavities and the protrusions.

4. The tool as claimed in claim 1 , wherein the teeth include teeth made of industrial diamonds.

5. The tool as claimed in claim 1 , wherein the tool comprises more than one entrance.

6. A tool configured to produce protrusions and cavities located after each other along an edge of a floor panel, wherein the tool is a screw shaped cutter with an axis of rotation parallel with the edge of the floor panel, the axis of rotation extending in an axial direction, wherein the tool comprises rows of teeth including first and second rows of teeth which are directly adjacent to one another, wherein all teeth of the tool that are directly adjacent in the axial direction are offset relative to each other in a rotational direction of the tool, and where a cutting diameter of the tool is smaller on an entrance side than on an opposite exit side.

7. A tool configured to produce protrusions and cavities located after each other along an edge of a floor panel, wherein the tool is a screw shaped cutter with an axis of rotation parallel with the edge of the floor panel, wherein the tool comprises rows of teeth including first and second rows of teeth which are directly adjacent to one another, wherein teeth of the first row of teeth contact teeth of the second row of teeth, and where a cutting diameter of the tool is smaller on an entrance side than on an opposite exit side.

8. The tool as claimed in claim 6 , wherein a pitch of the tool defines the intermediate distance of the cavities and the protrusions.

9. The tool as claimed in claim 6 , wherein the teeth of the rows of teeth include teeth made of industrial diamonds.

10. The tool as claimed in claim 6 , wherein the tool comprises more than one entrance.

11. The tool as claimed in claim 6 , wherein the rows of teeth include double screw rows of teeth.

12. The tool as claimed in claim 1 , wherein the tool has a longitudinal side and an end side, wherein the axis of rotation extends through the end side, wherein the tool is configured to produce protrusions and cavities in the floor panel with the longitudinal side and not the end side.

13. The tool as claimed in claim 6 , wherein the tool has a longitudinal side and an end side, wherein the axis of rotation extends through the end side, wherein the tool is configured to produce protrusions and cavities in the floor panel with the longitudinal side and not the end side.

14. The tool as claimed in claim 1 , wherein the axis of rotation extends in an axial direction, and wherein all teeth of the tool that are directly adjacent in the axial direction are offset relative to each other in the rotational direction of the tool.

15. The tool as claimed in claim 6 , wherein the first and second rows of teeth include teeth which are offset in the rotational direction of the tool and which are formed as a single monolithic piece of material.
