Abstract: Interconnectable panels having tongue-and-groove connections are mechanically connected to each other by first moving two panels into an intermediate position and then pivoting one panel with respect to the other. The underside of the tongue of one panel has a depression, while the groove of another panel has a protruding lower lip. The lower lip has a projection that fits in the depression when the two panels are in the intermediate position.

Abstract: The invention relates to a method for the production of a lignocellulose product from a) at least one material containing lignocellulose, b) a resin-based binding agent and (c) an organic compound comprising at least one first and second functional group. The first functional group is an oxidizable functional group and the second functional group is a group which can react with the binding agent forming a substantially covalent bond. The reactand and reaction conditions of the method are selected in such a way that substantially covalent cross-polymerization occurs between the material containing lignocellulose and the binding agent. The lignocellulose products produced according to the inventive method contain less binding agent and have improved physical-chemical properties.

Abstract: The technical problem of the invention is to improve the wetting of wood fibers with a binding agent. This technical problem is solved according to the present invention by a device for wetting wood fibers (10, 109) with a binding fluid, with a transport pipe (16, 105) for transporting the wood fibers (10, 109), with a fan (14, 106) for generating a transport air current, with a guide tube (17, 109) connected to the transport pipe (16, 105), with a fan (20, 110) for generating a conveying air current in the guide tube (17, 109), with means (27, 12) for supplying the binding fluid in the guide tube (17, 109). The invention also relates to a process for wetting wood fibers with a binding fluid.

Abstract: The invention relates to a large-size OSB-board having improved technical and mechanical properties. The aim of the invention is to solve the technical problems posed by an OSB-board which is suitable for using on large surfaces and also, for example, for the construction of buildings. To this end, the board has a width of at least 2.60 m and a length of at least 7.0 m, and the flectional elasticity module is it least 700 N/mm2 in the main loading direction.

Abstract: An interconnectable panel has a pair of surfaces on a lateral edge that adjoins a second pair of surfaces on a complementary lateral edge of another panel when the two panels are interconnected. The edge profiles are such that the first pair of adjoined surfaces has a cross-sectional contour in the shape of a segment of a circle. The circle has a center lying in the upper sections of the connected lateral edges. The circle also has a radius measured from the center to the first pair of adjoined surfaces. The second pair of adjoined surfaces is spaced away from the center of the circle by a distance greater than the radius. That distance increases in a direction away from the first pair of adjoined surfaces.

Abstract: A joint between two components (2, 4), with both components (2, 4) having joint faces (6, 8) which at least partially correspond with one another, which at least partially press against one another in the jointed state. The technical problem, on one hand, of preserving the advantages of an adhesive joint in comparison to mechanical joining systems, but simultaneously not increasing the outlay by the consumer and the outlay for handling the components, is solved in that a matrix (14, 16) is positioned on at least part of at least one of the joint faces (6, 8), multiple capsules (18) are positioned distributed in the matrix (14), a material of a reaction adhesive system is contained in the capsules (18), and at least a part of the capsules (18) at least partially release the material contained in them under external action. Also, a component having at least one joint face and a method for producing an adhesive matrix on a joint face.

Abstract: A particle board, a fiberboard or an oriented strand board (25) is formed by the process according to the invention from a mixture of a comminuted cellulose material and a binder, especially a synthetic resin containing an unsaturated oligimer, that is hardenable by electron radiation. The process of the invention includes first forming a loosely scattered layer (4) of the mixture, e.g. on a conveyor belt, then compressing the layer in a press device (16), after performing a pre-compression in a pre-press in Some embodiments, and rapid setting of the layer (4) by means of electron radiation from an electron radiation device (22). Unlike the known processes that only use a thermosetting binder, the inventive method is hindered neither by heat transfer to the center of the board nor by a non-uniform humidity profile. High quality boards may be produced at a high yield without splitting and these boards require no conditioning storage.
