摘要： Floor panels and floor elements therefore are made of sheet-shaped cores which are formed with sealing means for preventing or counteracting changes in the properties of the floor panels caused by moisture. A floor panel, including a body having a core, in which floor panel at least two opposite parallel joint edge portions are provided with connectors for mechanical joining of the floor panel in the horizontal direction with similar floor panels, the connectors having active locking surfaces for cooperation with corresponding active locking surfaces of adjacent floor panels after the floor panel has been joined therewith, the core having an upper surface layer, wherein a material seal of a resilient surface layer covers the upper surface layer of the core.

摘要： 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 the tongue has a total width that varies in the longitudinal direction of the tongue.

摘要： Floorboards which have a core and a surface layer and are provided with decorative joint edges which are formed by removing the surface layer. A method for making a floorboard, or a floor element that is to be divided into at least two floorboards, the method including making a core from a sheet shaped material, from which a part of a locking system for vertical locking of the floorboards is to be formed, impregnating and/or staining the core surface with a substance at least in portions which in the completed floorboard will constitute a joint edge of the completed floorboard, and arranging an surface layer on the core surface.

摘要： 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.

摘要： Floor panels which are provided with a mechanical locking system including tongue and grooves provided with protrusions and cavities which are displaceable in relation to each other. A set of floor panel provided with a locking system including a displaceable tongue in a displacement groove in a first edge of a first floor panel, cooperating for vertical locking of the edges with a tongue groove in adjacent second edges of a second floor panel, the locking system further including a locking strip with a locking element in one edge which cooperates, for horizontal locking of the edges, with a locking groove in an adjacent edge, the displaceable tongue includes a protrusion and the displacement groove a cavity, the protrusion is slideable against a wall of the cavity to obtain a displacement of the tongue in a first direction perpendicular to the edges and thereby the vertical locking of the edges.
