Abstract

Floorboards with a mechanical locking system that allows movement between the floorboards when they are joined to form a floating floor.

Claims (21)

1. Equipment for production of building panels, having a horizontal plane which is parallel with a panel surface, the equipment comprising:

a chain, a belt, a pressure shoe and a tool set, the chain and the belt are arranged to displace the building panels relative to the tool set and the pressure shoe, in a feeding direction, the pressure shoe is arranged to press towards a rear side of the building panels, the tool set is arranged to form an edge portion of the building panels when the building panels are displaced relative to the tool set,

wherein one of the tools of the tool set forms a guiding surface in the building panels, the pressure shoe has a guiding device which cooperates with the guiding surface and prevents deviations in a direction perpendicular to the feeding direction and parallel to the horizontal plane,

wherein the building panel is a floor board with a mechanical locking system, and

wherein the guiding surface comprises a groove, the groove being in an edge portion of the floor board where at least one part of the locking system is formed.

2. The equipment as claimed in claim 1 , wherein the tool set comprises milling tools.

3. The equipment as claimed in claim 1 , wherein the tool set comprises at least five different tools.

4. The equipment as claimed in claim 3 , wherein said groove defines the guiding surface for said at least five different tools.

5. The equipment as claimed in claim 1 , wherein the guiding device is attached inside the pressure shoe.

6. The equipment as claimed in claim 5 , wherein said groove opens towards a rear side.

7. The equipment as claimed in claim 1 , wherein the mechanical locking system comprises a locking element which cooperates with a locking groove and locks the floorboards horizontally parallel to the horizontal plane.

8. Equipment for production of building panels, having a horizontal plane which is parallel with a panel surface, the equipment comprising:

a chain, a belt, a pressure shoe and a tool set, the chain and the belt are arranged to displace the building panels relative to the tool set and the pressure shoe, in a feeding direction, the pressure shoe is arranged to press towards a rear side of the building panels, the tool set is arranged to form an edge portion of the building panels when the building panels are displaced relative to the tool set,

wherein one of the tools of the tool set forms a guiding surface in the building panels, the pressure shoe has a guiding device which cooperates with the guiding surface and prevents deviations in a direction perpendicular to the feeding direction and parallel to the horizontal plane,

wherein the building panel is a floor board with a mechanical locking system, such locking system comprising a locking element which cooperates with a locking groove and locks the floorboards horizontally parallel to the horizontal plane, and

the guiding surface comprises a groove open towards a rear side and the groove being in an edge portion of the floor board where at least one part of the locking system are formed.

9. The equipment as claimed in claim 8 , wherein the tool set comprises milling tools.

10. The equipment as claimed in claim 8 , wherein the tool set comprises at least five different tools.

11. The equipment as claimed in claim 10 , wherein said groove defines the guiding surface for said at least five different tools.

12. The equipment as claimed in claim 8 , wherein the guiding device is attached inside the pressure shoe.

13. The equipment as claimed in claim 12 , wherein said groove opens towards a rear side.
