Abstract: Floor panels are provided with a mechanical locking system having small local protrusions which reduce displacement along the joint when the panels are laying flat on the sub floor and locked vertically and horizontally.

Abstract: Floorboards comprising a core and a surface layer with curved edge portions, which are formed by a compression of the core.

Abstract: The invention relates to a locking system for mechanical joining of floorboards (1, 1?), a floorboard having such a locking system and a flooring made of such floorboards. The locking system has mechanical cooperating means (36, 38; 6, 8, 14) for vertical and horizontal joining of adjoining floorboards. The means for horizontal joining about a vertical plane (F) comprise a locking groove (14) and a locking strip (16) which is located at opposite joint edge portions (4a, 4b) of the floorboard (4). The locking strip (6) projects from the joint plane (F) and has an upwards projecting locking element (8) at its free end. The locking groove (14) is formed in the opposite joint edge portion (4a) of the floorboard at a distance from the joint plane (F). The locking groove (14) and the locking element (8) have operative locking surfaces (10, 11).

Abstract: Floorboards for installation of floors in herringbone pattern are formed with two opposite sides inverted relative to each other. The invention further comprises methods for producing and making floorings comprising such floorboards, as well as fitting pieces and sets of parts for such floorings.

Abstract: A device for coating surface portions of a board material with a liquid material. The device includes a wheel which transfers the coating material and compressed air which positions the coating material. A method for surface coating and a floorboard with a finished surface portion.

Abstract: The invention relates to a strip for a building board (2), exhibiting a board body (S) which is formed with a gripping stud (24). The strip (10) extends from the body (S) and from which are formed gripping elements (26, 28), which are bent round the gripping stud (24) for mechanical fastening of the strip (10) to the body (S), as well as a locking element (12) for enabling mechanical joining of the board (2) to similar boards.

Abstract: A locking system for mechanical joining of floorboards has a locking groove which is formed in the underside of and extends in parallel with the first joint edge at a distance from the joint plane, and a portion projecting from the lower part of the second joint edge and below the first joint edge and integrated with a body of the board. The projecting portion supporting at a distance from the joint plane a locking element cooperating with the locking groove and thus positioned entirely outside the joint plane seen from the side of the second joint edge, the projecting portion having a different composition of materials compared with the body of the board. The projecting portion presents at least two horizontally juxtaposed parts, which differ from each other at least in respect of the parameters material composition and material properties.

Abstract: Floorboard and openable locking system therefor comprise an undercut groove on one long side and projecting tongue on an opposite long side of the floorboard. The undercut groove has a corresponding upwardly directed inner locking surface at a distance from its tip. Tongue and undercut groove are formed to be brought together and pulled apart by pivoting motion with a center close to the intersection between the surface planes and common joint plane of two adjoining floorboards. The undercut is produced by at least two disk-shaped cutting tools with rotary shafts inclined relative to each other to form first an inner part of the undercut portion of the groove and then a locking surface positioned closer to the opening of the groove. Installation method for a floor of such boards, manufacturing method for manufacturing the undercut groove and a wedge-shaped tool for laying of the floorboards is also disclosed.

Abstract: The invention relates to a locking system for mechanical joining of floorboards (1, 1?) which have a body (30), a lower balancing layer (34) and an upper surface layer (32). A strip (6) is integrally formed with the body (30) of the floorboard (1) and extends under an adjoining floorboard (1?). The strip (6) has a locking element (8), which engages a looking groove (14) in the underside of the adjoining floorboard (1?) and forms a horizontal joint. A tongue (38) and a tongue groove (36) form a vertical joint between upper and lower plane-parallel contact surfaces (43, 45) and are designed in such manner that the lower contact surfaces (45) are on a level between the upper side of the locking element (8) and a plane containing the underside (3) of the floorboard. The invention also relates to a floorboard having such a locking system, a floor made of such floorboards, as well as a method for making such a locking system.

Abstract: Floorboards with a surface of flexible fibers for laying a mechanically joined floating floor, and methods for manufacturing and profloorings containing such floorboards.

Abstract: Floorboards for mechanical joining of floors in a herringbone pattern and in parallel rows with horizontal connectors which on the short sides have cooperating locking surfaces which are designed differently from the cooperating locking surfaces on the long sides.
