A vertical joint system for substrates is formed with joints and which engaged by relative motion in a direction perpendicular to major surfaces and of the substrate. The joints are configured to enable relative rotation of up to 3 degrees while maintaining engagement of the joints. The joints and are further configured to form two locking planes one on each of the inner and outer most sides of the joint. Engagement about the locking planes is provided by transverse outward extending surfaces. At least one surface in each pair of engaging surfaces is smoothly curved. The joints and can be further arranged to provide a third locking plane parallel to and between the locking planes. The joints are disengaged by combination of a downward rotation of one joint relative the other then application of a downward force.

A recess is provided at the surface of a floor or wall covering between two panels mechanically coupled to each other by a male coupling part and a female coupling part. The recess may include a first recess cut out or otherwise provided at the female edge through the top layer and extending into the substrate. The recess may have a second recess cut out or otherwise provided at the male edge through the top layer and extending into the substrate. The recess includes a grouting material.

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 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.

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.

A vertical joint system for a surface covering panel having an upper and lower surfaces, and a plurality of sides located between the upper and lower surfaces. The joint system has a male part along at least one side and a female part along an opposite side. The female part has a protrusion that extends from the lower surface and an outer most female surface on the protrusion. The male part has a recess that opens onto the lower surface with a portion of the recess forming an inner most male surface. The outer most female surface and the inner most male surface arranged so that when the male part of one surface covering panel is engaged with a female part of a second surface covering panel the outer most female surface overlies the inner most male locking surface at a first location and a second location.

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 present invention relates to a decorative tile panel for covering a floor, ceiling, or wall. Furthermore, the invention relates to a surface covering for a floor, ceiling or wall surface which is constructed by a multitude of neighbouring tile panels according to the invention, wherein the plurality of tile panels are preferably interconnected.

A coated panel may include at least a substrate and a top layer with a printed motif. The top layer may be provided on the substrate. The top layer may also include a transparent or translucent synthetic material layer, which is provided above the printed motif. The top layer and preferably at least the transparent or translucent synthetic material layer may include a foamable or foamed synthetic material.

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.
