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.
Claims15
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.
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.
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.
