Furthermore, the invention relates to a method for the production of such a light, single-layer derived timber product board.

Abstract: The present invention relates to a panel, in particular a wall, ceiling or floor panel, comprising a carrier layer made of a plastic material and a priming coat, wherein the priming coat comprises thereon an imprinted decorative pattern. Furthermore, the present invention relates to a method for manufacturing such a panel and a usage of a specific primer in such a panel.

Abstract: A method for coating a board of wood-based material, comprising the steps of providing a board of wood-based material; applying a first liquid coating; applying at least a second liquid coating onto the still wet first coating, so that a partial mixture of the coatings takes place; curing the applied coatings by means of radiation, wherein the coatings are selected so that the cured resultant coating has a hardness gradient wherein the hardness of the resultant coating decreases with increasing depth viewed from the surface of the resultant coating.

Abstract: The present invention relates to a heatable covering system for floors, ceilings, and walls. The covering system comprises covering panels which at least on one longitudinal edge comprise coupling means in order to be able to join covering panels with each other wherein the covering panels are provided with electrical heating means and have electrical contacting means in order to electrically contact the panels.

Abstract: The present invention relates to a direct printed lightweight panel, in particular a flooring panel, comprising a lightweight MDF or LDF carrier board with a density of ?750 kg/m3; a decor layer printed onto the carrier board; and a transparent protective coating. The different layers and coatings are applied in such a manner so that surface structures and/or optical characteristics of the carrier board are at least partially visible and thereby incorporated into the design of the decor layer.

Abstract: The invention relates to a panel which is suitable for use as wall and/or ceiling paneling, in addition to an associated method for laying said panels and a method for the production thereof. The inventive panel for a wall or ceiling comprises coupling means. The coupling means are embodied in such a way that the panel can be joined to other panels in various positions. Said positions can, for example, involve various distances between the longitudinal edges of two panels that are arranged in parallel. According to the inventive laying method, a first panel is engaged with a second panel in a first step, whereupon the panels assume an angular position in relation to each other. At least one of the panels, particularly the first panel, is pivoted in a second step on a common plane, whereupon the panels become locked in relation to each other.

Abstract: A device and method for elutriating and gluing wood chips. At least one elutriating apparatus is used to fractionate the wood chips into at least one coarse chip fraction and one fine chip fraction. The elutriating apparatus has a fall duct and is designed so that the chip fractions pass through different gluing regions in the fall duct. At least one gluing apparatus is provided in order to glue the chip fractions in the gluing regions. Thus, the chip fractions can be glued in a common apparatus specifically with a glue amount adapted to a particular average chip size.

Abstract: The invention relates to a floor covering as is frequently used in houses and apartments. The floor covering has on its underside a layer of thermoplastic material. This layer is connected in a fixed manner to the floor covering. The floor covering consists of wood, wood derivatives and/or synthetic materials. In order to produced said floor covering, the thermoplastic material is heated and applied, or rolled onto the underside of the floor covering. The latter exhibits excellent sound-proofing properties.

Abstract: A method and an apparatus for gluing wood particles, in particular wood strands, is described, as well as a method for the manufacturing of lignocellulosic products, in particular chip boards, oriented strand boards or fiber boards. Since the wood particles are blended in a blending device with a water-curable binder, in particular with polymeric diphenylmethane diisocyanate and moisture is added to the wood particles outside the blending apparatus, curing of the binder inside the blending apparatus, and as a consequence pollution thereof, can be avoided. Moreover, moisturizing outside the blending device can produce a particular even distribution of moisture.

Abstract: The invention relates to a heating device and in particular to an element of a floor heating device. Known floor heating devices comprise heating means which are arranged underneath floor coverings, for example, below stone plates, tiles, parquet elements or laminated panels. Those heating means can be made of electrically heatable films which are arranged close to the surface of a covering in order to directly heat the room.

Abstract: The invention relates to connection elements comprising a tongue (3) and a groove (10), and an additional locking element (6) which is connected thereto in a non-positive manner, which consists of a plastic or adhesive material and is especially embodied as a bar.

Abstract: The invention relates to a device for coating plates (6) in circulation. Said device comprises a transport system for transporting plates (6) and a feeding device (5) which can apply the coating material (8) to the surface of the plates. Means (7) for drying and/or hardening the coating material are provided next to the feeding device and above the plates. Contrary to state of the art devices, said inventive device comprises means which enable a material web (3) to pass between the transport elements for the transport of plates and means (7) for drying and/or hardening.

Abstract: A paper for a laminate panel includes a first layer that includes a resin impregnated decorative paper or a resin impregnated overlay; and a second layer of abrasion resistant particles uniformly distributed on and adhered to the first layer.

Abstract: The invention relates to panels comprising coupling means which permit the panels to be interconnected by form fit. A first panel comprises a projecting edge positioned laterally on its underside as the coupling element. A second panel comprises a projecting edge positioned laterally on its upper side as the coupling element. One of the aforementioned edges has a first projecting locking element which engages in a corresponding first cavity or recess of the other edge when the two panels are joined together. The panels comprise additional coupling elements which lock the panels by form fit in a vertical direction, in relation to the surface of said panels. The coupling elements are configured in such a way that one panel can be connected to the other panel by form fit, by lowering the former in relation to the latter. Two panels of the aforementioned type can be interconnected without adhesive in a particularly rapid manner.

Abstract: The invention relates to panels (1, 2) that can be interlinked without using glue. In the interlinked state of the panels, a cord (3) runs along the upper side of and between the panels. Said cord widens downwards and rests on the upper side of a spring (5) that forms the coupling element of a panel. The widening is preferably asymmetric. The inventive panels especially allow to provide a wall covering or a ceiling covering in an especially simple manner. The cord consists of a compressible material and prevents water from entering the gap between the panels. The design also compensates for effects related to expansion and shrinkage.
