A set of essentially identical floorboards each including a front face and a rear face extending in the horizontal plane, a core, and a surface layer, a mechanical locking system is arranged at least at two opposite edges for connecting a floorboard with an adjacent floorboard in a horizontal and a vertical direction, said mechanical locking system being configured for connecting the floorboard with the adjacent floorboard by vertical folding, wherein one of said opposite edges is provided with a horizontally extending protrusion at an upper edge, and wherein said protrusion is configured to overlap a surface groove at an upper edge of the other of said opposite edges, such that two connected and adjacent floorboards have upper overlapping edges.

A method is provided for manufacturing a panel that includes a substrate and a top layer provided on the substrate. The top layer may include a decor film and a transparent film. The decor film may be a printed synthetic material film chosen from the group consisting of a vinyl-based film, a polyethylene based film, a polyurethane based film, and a polypropylene film. A print may be situated on an upper side of the printed synthetic material film. The transparent film may be a thermoplastic synthetic material film the material of which is chosen from the group consisting of polyvinyl chloride, polyethylene, polyurethane, and polypropylene. The method may involve providing the decor film and the transparent film on the substrate by performing a first press treatment at an increased temperature to form a package of the substrate, the decor film, and the transparent film. The first press treatment may be performed by a calendar device or a continuous press device. A structure may be formed in the thermoplastic synthetic material that forms a surface of the package by performing a second press treatment using a press device with a structured press element at a temperature that is lower than the increased temperature.

A locking arrangement, including a panel with a locking groove; an edge strip with a first form; as well as a locking element placed at least partly or entirely between the edge strip and the panel. The locking element includes a protrusion inserted in the locking groove of the panel and configured to prevent the panel from detaching from the edge strip, and a second form matching with and received by the first form of the edge strip, and configured to prevent the locking element from detaching from the edge strip. In the presented method for assembling the locking arrangement, in its first step, the locking element is placed against the panel so that the protrusion is inserted in the locking groove of the panel, after which they are installed in the edge strip.

Panels are shown which are provided with a mechanical locking system allowing perpendicular connection with a snap action. A set of panels including a first and a second panel, an edge of the second panel is insertable into a groove of the first panel, when the panels are arranged essential perpendicular to each other, to obtain a mechanical connection between the first and the second panel, when the second panel is displaced essentially perpendicularly to the first panel.

A floor panel has a rectangular and oblong shape, and includes a substrate and a top layer provided on the substrate and forming a decorative side of the floor panel. The top layer is composed of a print provided on a carrier sheet and a transparent thermoplastic layer situated above the print. The substrate has a thickness from 2 to 10 millimeter and forms at least half of the thickness of the floor panel. The substrate is a polyurethane-based substrate and the transparent thermoplastic layer is polyurethane-based. The floor panel has a length of more than 1.1 meters and has a plurality of reinforcing layers situated outside the center line of the substrate. A reinforcing layer may be provided in combination with the substrate and the top layer.

The invention relates to a composite tile for an installation system, more particularly for the production of a floor covering or wall covering, comprising a tile of a floor covering or wall covering and a backing disposed on the lay-on face of the tile. The invention also relates to a connecting element for the connection of two composite tiles and to an installation system composed of composite tiles and also to a method for the fabrication of a composite tile. The backing consists of a fiber composite material, more particularly fiber cement.

Floor panels which are provided with a mechanical locking system including a displaceable tongue in a displacement groove. The tongue is moulded and provided with bendable protrusions. A building panel having an edge portion provided with a groove, in which a tongue formed as a separate part is received, wherein the tongue includes at least two bow shaped protrusions at a first long edge of the tongue, and wherein the protrusions are arranged bendable in the groove.

Floor panels which are provided with a mechanical locking system including an extruded flexible tongue in a sidewardly open groove which during a vertical folding motion is bent horizontally. A tongue adapted for being received in a sidewardly open groove of a floor panel, wherein the tongue, which is an elongated extruded section, when received in the groove is bendable in a plane substantially parallel with a front face of the floor panel, such that the tongue is at least partially resiliently displaceable inside said sidewardly open groove in said plane during locking of the floor panel with another floor panel and wherein a vertical protrusion, serving as a friction connection between the tongue and the groove, is arranged at an upper or lower part of the tongue, wherein a total width of tongue varies in a longitudinal direction of the tongue.

A floor panel includes a substrate and a top layer provided on the substrate. The top layer is composed of a print and a transparent thermoplastic layer having a thickness of 0.5 mm or less and being situated above said print. The floor panel, at least on two opposite edges, is provided with a straight or curved chamfer extending to below the global level of the print.
