    摘要: A panel element may be provided for a covering. In particular, a panel element for a floor, wall or ceiling covering, which covering may be formed by a plurality of panel elements of the same kind which are connected to one another. Each panel element has a basic body having a defined total thickness and upper and a lower surfaces. The basic body has in each case differently contoured longitudinal sides and in each case differently contoured end faces. One longitudinal side has groove-like contouring and the other longitudinal side has tongue-like contouring corresponding thereto.

    摘要: A method of producing a board for production of panels is provided comprising: providing particulate material comprising or consisting of particulate wooden material, producing glued particulate material by applying an adhesive to the particulate material, forming a spreading material mat by homogeneously spreading the glued particulate material onto a conveyor on which the spread glued particulate material is conveyed in a conveying direction, and producing a board by pressing the spreading material mat. A reinforcement material is applied to the spread glued particulate material parallel to the conveying direction during forming the spreading material mat and/or after forming the spreading material mat before any pressing of the spreading material mat such that the spreading material mat has at least one longitudinal reinforcement zone containing the reinforcement material. Boards can be obtained from which panels can be produced which have reinforced longitudinal and/or transversal edges.

    摘要: A flooring system is provided comprising a plurality of (identical) floor panels, which are mechanically connectable to each other along at least one pair of adjacent first and second opposite joint edges. The panels comprise locking elements for connecting said panels in both horizontal and vertical direction. In order to consider the often occurring situation that in panels—especially when stored under changing external conditions, especially changing humidity—might warp, the (vertical) locking element in the panels is constructed with a (slight) play, so that in the event that two panels have slightly different warp nevertheless can easily and reliably be mechanically connected with each other omitting the need to exert an excess of force to fit the panels.
