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.

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 are provided with a mechanical locking system including a flexible locking element in a locking groove which during a horizontal motion is displaced vertically. A panel system including a plurality of rectangular panels with long and short edges which are mechanically connectable to each other along at least one pair of adjacent edges, said panels each being provided with a tongue and groove formed in one piece with the panels for mechanically locking together said adjacent edges at right angles to the principal plane of the panels, thereby forming a vertical mechanical connection between the panels, said panels being provided with a first locking element at one first edge formed in one piece with the panel and a locking groove at an opposite second edge, the locking groove being open towards a rear side or a front side of the panel.

Floor panels are shown, which are provided with a mechanical locking system on long and short edges allowing installation with vertical folding and where the long edge locking system prevents separation of the short edges during the folding action. Floor panels with mechanical locking systems with a flexible and displaceable tongue allowing easy installation.

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.

Disclosed is a method for making a decorative groove between joint edges on a laminate floorboard. The floorboard includes an upper layer and an underlying layer. The method involves fixing the floorboard between at least one chain and at least one band, displacing the floorboard relative to a milling machine, and removing at least a part of the upper layer, so that a surface of the underlying layer is uncovered, by a tool that performs machining between the at least one chain. The surface of the underlying layer defines at least a portion of a visible width of the decorative groove.

Floor panels are provided with a mechanical locking system having small local protrusions which reduce displacement along the joint when the panels are laying flat on the sub floor and locked vertically and horizontally. A method to install a floor comprising a plurality of rectangular floor panels laying in parallel rows on a sub floor with long and short edges which are connectable to each other along one pair of adjacent long edges and one pair of adjacent short edges.

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 bamboo laminated lumber is provided having structural characteristics meeting or exceeding dimensionally equivalent wood based components. The bamboo laminated lumber is formed from bamboo laminated elements laminated and joined together to form dimensional lumber and engineered lumber components. The bamboo laminated lumber element comprises a combination of linear bamboo starter boards being halves of timber bamboo canes pressed flat with the inner pith surfaces laminated together with the grain aligned and skewed bamboo starter boards being halves of timber bamboo canes pressed flat with the inner pith surfaces laminated together with the grain offset from centerline at a specified angle. Top and bottom linear bamboo starter boards are laminated to a central skewed bamboo starter board yielding a bamboo laminated lumber element.

Disclosed is a tile unit (10) that includes a resin net (20), a plurality of tiles (30) disposed on a front side of the resin net, and a magnet sheet (40) disposed on a back side of the resin net, with the tiles being bonded and fixed to the magnet sheet with the resin net interposed therebetween.
