A panel including a centrally located core, at least one first coupling part and at least one second coupling part connected respectively to opposite edges of the core, which first coupling part includes an upward tongue, at least one upward flank lying at a distance from the upward tongue and an upward groove formed in between the upward tongue and the upward flank wherein the upward groove is adapted to receive at least a part of a downward tongue of a second coupling part of an adjacent panel: which second coupling part includes a downward tongue, at least one downward flank lying at a distance from the downward tongue, and a downward groove formed in between the downward tongue and the downward flank, wherein the downward groove is adapted to receive at least a part of an upward tongue of a first coupling part of an adjacent panel.

A joining system for floor panels comprising a female coupling formed in a first floor panel and a male coupling formed in a second floor panel, the female coupling comprising: a female coupling recess being arranged on a female coupling tongue protruding away from a main portion of the first panel towards the adjoining second floor panel, the female coupling recess being adapted to receive a male coupling tongue projecting from the adjoining second floor panel in a direction away from a main floor surface plane in which the floor panels are laid, the female coupling further comprises an upper guiding surface being located on a side of the female coupling recess on the first panel forming a guide for the male coupling tongue upon insertion thereof.

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.

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.

The invention relates to a method for laying a modular surface covering system on a surface to the covered and an underlayment element for use in such a method and modular surface covering system. The underlayment element includes a planar base with a raised edge along two interconnected sides of the underlayment element. First coupling elements in the form of recesses are provided along the two sides with the raised edge and second coupling elements in the form of protruding tongues are provided along the other two interconnected sides. The finishing layer elements are clamped between raised edges of coupled underlayment elements. The top surface of a raised edge between finishing layer element provides the grout effect. The underlayment elements enables one to lay a surface covering system with a multitude of pattern, e.g. as grid pattern, brickwork pattern, herringbone pattern, etc.

A floor panel for forming a floor covering, wherein this floor panel is at least composed of a substrate; wherein the floor panel, on at least one pair of opposite edges, comprises coupling parts, which coupling parts allow that two of such floor panels can be coupled to each other by means of a downward movement of one floor panel in respect to the other floor panel; wherein these coupling parts, in the coupled condition of two of such floor panels, form a first locking system, which effects a locking in a first direction perpendicular to the plane of the floor panels, and form a second locking system, which effects a locking in a second direction perpendicular to the edges and in the plane of the floor panels.

A floor board including a decorative surface layer applied to a substrate, where the substrate has MDF or HDF material at a side edge thereof, where the side edge is treated both with an impregnation agent and/or a sealing agent based on a superabsorbing material. Also a method for manufacturing such floor boards.

A snap-fit connection arrangement includes groove and tongue strips respectively having a groove and tongue, and first and second attachment regions for placement along first and second components, respectively. The groove and tongue strips respectively extend in first and second longitudinal directions transversely to their respective cross sections. Cross-sectional contours of the tongue and the groove correspond to each other through use of latching elements so that a snap-fit connection can be established as the tongue is inserted in a joining direction into the groove. The snap-fit connection allows for relative movement between the tongue and groove strips along at least one of the longitudinal directions and prevents relative movement between the tongue and groove strips transversely to at least one of the longitudinal directions. The tongue includes a latching recess comprising an undercut that extends along and within the tongue and is configured for latching engagement with a rib.

Provided is a panel including at least one first coupling part. The first coupling part includes an upward tongue, at least one upward flank lying at a distance from the upward tongue and an upward groove formed in between the upward tongue and the upward flank. The side of the upward tongue facing towards the upward flank is the inside of the upward tongue and the side of the upward tongue facing away from the upward flank is the outside of the upward tongue. At least a part of an upper side of the upward tongue is inclined relative to the plane of the panel, such that the upper side of the upward tongue includes a highest point. The upward tongue has a width, wherein the highest point of the upward tongue is arranged less than 50% of the width from the outside of the upward tongue.

A floor, wall or ceiling panel comprises a core and a decorative top layer provided on the core. The core comprises a magnesium oxide-based board material, and wherein the aforementioned panel, on at least two opposite edges, is provided with coupling means allowing that two of such panels can be interlocked at the respective edges.
