Abstract: The invention concerns hard panels for floor coverings, which are provided, at least on two opposite edges, with coupling devices made in one piece with the panels wherein similar panels may be coupled together to form a floor covering, wherein these coupling devices provide for an interlocking in a direction perpendicular to the plane of coupled panels, as well as in a direction perpendicular to the edges concerned and parallel to the plane of coupled panels. These coupling devices comprise a tongue and a groove. A lip which is situated on the bottom side of the groove is longer than a lip located on the top side of the groove. The edge which is provided with the tongue is made elastically flexible.

Abstract: The invention relates to a locking system for mechanical joining of floorboards (1) constructed from a body (30), a rear balancing layer (34), and an upper surface layer (32). A strip (6), which is integrally formed with the body (30) of the floorboard and which projects from a joint plane (F) and under an adjoining board (1), has a locking element (8) which engages a locking groove (14) in the rear side of the adjoining board. The joint edge provided with the strip (6) is modified with respect to the balancing layer (34), for example by means of machining of the balancing layer under the strip (6), in order to prevent deflection of the strip (6) caused by changes in relative humidity. The invention also relates to a floorboard provided with such a locking system, as well as a method for making floorboards with such a locking system.

Abstract: Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical snap folding that could be accomplished automatically without tools and where the short edge locking system has a tongue made in one piece with the panel. The floor panels may have a first and a second connector at the long edges that are configured to obtain a minimum of friction facilitating a displacement, by a spring back force from the bending of a short edge locking strip, of a new panel in a horizontal direction along the long edge during the vertical snap folding action.
