A floor panel contains opposite edges that contain coupling parts to link two floor panels. These coupling parts contain locking planes: first and second locking planes on the first edge with an enclosed angle between 90° and 175°; and third and fourth locking planes on the second edge with an enclosed angle between 90° and 175°. The first locking plane is closer to the top of the floor panel than the second locking plane. The angle with the surface of the floor panel of the first locking plane is smaller than the second locking plane. The angle with the floor plane surfaces of the third locking plane is smaller than that of the fourth locking plane. The second locking plane is provided for interaction with the fourth locking plane of a coupled panel. The first locking plane is provided for interaction with the third locking plane of a coupled panel.

The invention relates to a glue-down decorative floor covering system. The invention also relates to a glue-down floor covering realized by a plurality of tiles of the glue-down floor covering system according to the invention. The invention further relates to a tile for use in a glue-down floor covering system according to the invention.

A set of panels includes first and second panels and a mechanical locking device for assembly by vertical relative displacement of the panels. A locking strip extends from a first edge of the first panel in a direction parallel to first and second panel surfaces of the first panel. The locking strip includes a locking strip edge, and first and second locking strip surfaces respectively extending in directions substantially corresponding to those of the first and second panel surfaces. A locking element of the locking strip cooperates with a locking groove at the second edge of the second panel for locking in a direction parallel to the first panel surface. Opposite edges respectively include cooperating tongue and tongue groove for vertical locking. A flexing groove extends from a first locking strip surface/first edge transition and into the first panel at an angle α from the first panel surface.

The present invention relates to a floor panel and to a floor. The floor panel according to the invention includes a core provided with an upper and lower surface, and a first and second core flank at a first and second side of the core, respectively. The floor panel includes a first coupling part and a second coupling part provided at the first side and the second side of the core, respectively. Each of the coupling parts includes an inner side flank, an outer side flank, and an upper portion flank connecting the inner side flank to the outer side flank. According to the invention, a portion of the first core flank and an upper portion of the outer side flank of the second coupling part are inclined such that when the floor panel is coupled to an adjacently arranged further floor panel these upper portions lie against each other for the purpose of providing a locking in a vertical direction. In addition, a first upper portion flank of the tongue of the first coupling part includes a curved recess and the groove of the second coupling part may include a bulge complimentary to the curved recess.

Disclosed is a method for producing panels from a board which includes dissecting the board along predefined lines. The board includes a core material board and is laminated with a laminate material layer. The board is dissected along an impressed region running linear over the complete surface of the laminate material layer. Also disclosed are a press plate, a method for the production of a board having an impressed region, and a board for producing the panels.

Floorboards provided with a mechanical locking system including a locking strip protruding from a first edge of a first floorboard. The locking strip is provided with a locking element configured to cooperate with a locking groove at a lower side of a second edge of a second floorboard for locking the first edge and the second edge in a horizontal direction. The first edge and the second edge are configured to be assembled by a vertical downward motion of the second edge towards the first edge. The second edge is provided with a calibrating groove adjacent the locking groove. Also, a method for producing a mechanical locking system.

A rectangular panel which, on the first and on the second pair of opposite edges, has coupling parts configured for easy installation in a wall or ceiling covering. A locking occurs between the coupled panels; and a wall or ceiling covering that includes such panels

The present invention relates to a panel, in particular a floor panel, comprising a 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 comprises an upward tongue, at least one upward flank lying at a distance from the upward tongue and an upward groove, which second coupling part comprises a downward tongue, at least one downward flank lying at a distance from the downward tongue, and a downward groove, wherein the upward tongue is provided with a first locking element; wherein the downward flank is provided with a second locking element, wherein the downward tongue is provided with a third locking element, wherein the upward flank is provided with a fourth locking element.

A set of panels includes first and second panels and a mechanical locking device for assembly by vertical relative displacement of the panels. A locking strip extends from a first edge of the first panel in a direction parallel to first and second panel surfaces of the first panel. The locking strip includes a locking strip edge, and first and second locking strip surfaces respectively extending in directions substantially corresponding to those of the first and second panel surfaces. A locking element of the locking strip cooperates with a locking groove at the second edge of the second panel for locking in a direction parallel to the first panel surface. Opposite edges respectively include cooperating tongue and tongue groove for vertical locking. A flexing groove extends from a first locking strip surface/first edge transition and into the first panel at an angle α from the first panel surface.

A floor panel including at least one substrate and a top layer, where the substrate includes at least one first layer of a first thermoplastic material and a second layer of a second thermoplastic material. The second layer is adjacent to a first side of the first layer and the second layer provides the floor panel with its underside. The first layer is characterized by a first colour with saturation value S1 in the HSL colour space and the second layer is characterized by a second colour with saturation value S2 in the HSL colour space, where S1 is less than S2.
