The invention relates to a material board, in particular an engineered wood board (1) comprising at least one core layer (2) made of strands (3), and outer layers (4, 5) made of chips (6), characterised in that one or both of the outer layers (4, 5) is/are designed as partial-coverage outer layers such that individual strands (3) extend at least partly through the outer layer (4, 5) up to the board surface, thereby forming interruptions in the outer layer (4, 5).

A method for producing a composite material comprises the following steps: comminuting wood elements into wood fragments; crushing the wood fragments; mixing the wood fragments with an adhesive agent and/or a bonding agent; and pressing the mixture of wood fragments and the adhesive agent and/or bonding agent.

A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.

A method for manufacturing a fiber formed body includes forming a fiber board into a predetermined outer shape while forming a pattern on an outer surface of the fiber board by compressing the fiber board, a forming at least one positioning member by compressing the fiber board, and positioning, relative to a cutoff device, the fiber board using the positioning member, and cutting off a cutoff target part of the fiber board using the cutoff device. In the method for manufacturing the fiber formed body, formation of the pattern during the forming of the outer shape and formation of the positioning member during the forming of the positioning member are simultaneously performed.

An extrusion press device (1) and a method are for an extrusion material (3) which has small loose plant parts, in particular wood chips, provided with binder. The extrusion press device (1) has an extrusion press (7) which presses the supplied loose extrusion material (3) and shapes same into a strand (8) and which advances the strand in an extrusion direction (9). The extrusion press (7) has a shaping device (21) which forms one or more inner tubular cavities in the strand (8) in the extrusion direction (9). The extrusion press (7) forms a continuous strand (8) with one or more inner tubular cavities (29) during the extrusion process, the cavities being closed by the extrusion material (3) at the end face.

A method to manufacture, on one or more production or manufacturing lines, an integrated roofing product, such as a roofing panel or roofing plank. A blank panel of engineered wood is cut or sawn into a plurality of raw planks or raw panels, each with an outer face, an inner face, a top edge, and a bottom edge. Each raw plank or panel is then processed by cutting or routing a profile into the top edge, the bottom edge, or both; affixing a gasket seal to the profile in the top edge or the bottom edge, or both; coating at least some or all of the outer face with a silicone-based or silicone-containing coating; applying a mix of granules and/or sand to the silicone-based coating while wet; and curing the coated plank or panel. A plurality of panels or planks can then be installed on a roofing structure.

A method for producing an ultra-stable and enhanced solid wood flooring for under-floor heating via surface compression technique includes: subjecting, while subjecting a solid wood to surface compression and enhancement, the solid wood to primary stabilization treatment by controlling a temperature of a hot pressing plate to obtain a compressed enhanced solid wood; putting the compressed enhanced solid wood into a heat treatment tank; and subjecting the compressed enhanced solid wood to secondary stabilization treatment by controlling a pressure and a temperature of steam or air in the heat treatment tank and a treatment time to obtain a finished product. The ultra-stable surface-compressed enhanced solid wood flooring produced by the method features high dimensional stability, low set-recovery after water absorption, and desired moisture and heat resistance.
