  • Publication number: 20130328238
    Abstract: A device and a method for specifically influencing the technological properties of individual regions of a sheet-like material are provided, including the following steps: a) fixing the sheet-like material or a pre-compacted material nonwoven or a material fibre cake on a workbench, b) placing at least one applicator on the upper side and/or the underside of the sheet-like material, the material nonwoven or the material fibre cake, c) specifically moving the at least one applicator on the upper side and/or the underside and pressing an improving medium into partial regions of the sheet-like material, the material nonwoven or the material fibre cake in a predetermined amount and under a predetermined pressure, d) optionally, subsequently pressing the pre-compacted material nonwoven or the material fibre cake to form a sheet of the desired thickness.

  • Patent number: 8394302
    Abstract: A method for producing a wood-fiber board, which has a pattern on the top, in that glued wood fibers are scattered at least one layer to form a fiber cake, and the fiber cake is subsequently compressed under pressure and temperature to form a board of the desired thickness, is characterized in that the pattern is applied to the fiber cake before compression. An installation for producing a wood-fiber board with a scattering device, by means of which a fiber cake comprising at least one layer of wood fibers glued with resin is scattered, and a conveyor device, which conveys the fiber cake in a process direction to a pressing device in which the fiber cake is pressed to form a board of the desired thickness, is characterized in that a printing device is arranged above the conveyor device between the scattering device and the pressing device.

  • Publication number: 20120027957
    Abstract: A method for the refinement of a panel and an apparatus for the refinement of a panel according to a method of this type. The method for the refinement of a panel includes: unpacking of a panel having a core made from wood material from a transport-safe packaging, a grounding in the form of at least one synthetic resin layer pressed together with the core and, if appropriate, a primer being arranged on a top side of the core, and a coating being arranged on a core underside lying opposite the top side of the core, and connection and locking means being attached to at least two mutually opposite side faces; application of a decorative layer having a decoration to the grounding or primer; and application of at least one wear layer to the decorative layer.

  • Publication number: 20120023856
    Abstract: A method for the production of grounded panels and to a panel having a core made from a wood material board. The method includes provision of a wood material board, application of a grounding in the form of a synthetic resin layer to at least one topside of the wood material board, application of a coating to an underside, lying opposite the topside of the wood material board, of the wood material board, pressing of the layer build-up consisting of the wood material board, grounding and coating under the influence of pressure and, if appropriate, temperature, division of the grounded and coated wood material board into individual panels, cutting machining of side faces of the panels for the incorporation of connection and locking means, and transport-safe packaging of the grounded panels.

  • Patent number: 8092865
    Abstract: A method for producing a building board. The method includes applying synthetic-resin layers to the top side and/or the bottom side of a support board made of a wood material or a mixture of wood material and plastic. The layered structure is compressed under the impact of pressure and temperature. At least one of the synthetic-resin layers expands during compressing.
