Abstract

Floorboards with a mechanical locking system that allows movement between the floorboards when they are joined to form a floating floor. A semi-floating floor including rectangular floorboards joined with a mechanical locking system and in which locking system the joined floorboards have a horizontal plane which is parallel to a floor surface and a vertical plane which is perpendicular to the horizontal plane, said locking system having mechanically cooperating locks for vertical joining parallel to the vertical plane and for horizontal joining parallel to the horizontal plane of a first and a second joint edge and in which locking system a vertical lock including a tongue which cooperates with a tongue groove and the horizontal lock including a locking element with a locking surface which cooperates with a locking groove.

First claim

1 - 7 . (canceled)

8 . A method for producing a building panel having a horizontal plane which is parallel with a front side surface of the building panel, wherein the method comprises:
displacing the building panel in a feeding direction relative a tool set and a pressure shoe, via a chain and a belt,
pressing on a rear side of the building panel via the pressure shoe,
forming an edge portion of building panel via a first tool of the tool set, when the building panel is displaced relative the tool set,
forming a guiding surface in building panel via a second tool of the tool set, and
guiding the building panel via a guiding device of the pressure shoe which cooperates with the guiding surface.

9 . The method as claimed in claim 8 , wherein the guiding prevents deviations in a direction perpendicular to the feeding direction and parallel to the horizontal plane.

10 . The method as claimed in claim 8 , further comprising forming, via the tool set, a mechanical locking system comprising a locking element at a first edge of the building panel and a locking groove at a second edge of the building panel for locking the building panel horizontally parallel to the horizontal plane.

11 . The method as claimed in claim 10 , wherein the guiding surface is a guiding groove open towards the rear side of the building panel.

12 . The method as claimed in claim 11 , wherein the guiding groove is a part of the mechanical locking system.

13 . The method as claimed in claim 10 , wherein the guiding surface is a part of the locking groove.

14 . The method as claimed in claim 8 , wherein the building panel is a floorboard.

15 . The method as claimed in claim 8 , wherein the second tool of the tool set is attached to a side of the pressure shoe.

16 . The method as claimed in claim 8 , wherein the first tool of the tool set is unattached to a side of the pressure shoe.

17 . The method as claimed in claim 8 , wherein building panel is guided via two guiding devices on opposite sides of the building panel.

18 . The method as claimed in claim 8 , further comprising supporting the front side surface of the building panel via a support.

19 . The method as claimed in claim 8 , wherein the belt is provided on the rear side of the building panel with the pressure shoe.

20 . The method as claimed in claim 8 , wherein the belt travels through a recess in the pressure shoe.
