Abstract: A process for the production of OSB wood-based panels including: a) producing wood strands from suitable wood logs; b) treating at least part of the wood strands with steam at a temperature between 80° C. and 120° C. and a pressure between 0.5 bar and 2 bar; c) drying the steam-treated wood strands; d) gluing the steam-treated and dried wood strands and, optionally, gluing the non-steam treated wood strands with at least one binder; e) scattering the glued wood strands onto a conveyor belt; and f) pressing the glued wood strands into an OSB wood-based board. The steam treatment takes place after the wood strands have been produced and made available, or after the wood strands have been sifted and separated according to the use of the wood strands for the middle and top layers of the panel. Also, an OSB wood-based panel made using the process.

Abstract: A chipping machine includes a debarking assembly, a chipper assembly, and a log advance system to conveys logs through the chipping machine and into contact with the debarking assembly and chipper assembly. A rotating chipper disk cuts chips from the log. A housing encloses the chipper disc and includes a spout that provides an exit path for chips out of the housing. The chipper assembly includes a first path for collecting bark and directing bark out of the machine. A second path that is separate from the first path collects trash and directs the collected trash to first path and out of the machine. An inlet of the second path is an opening formed in a base of the housing. The second path includes a chute onto which trash falls and then slides under the force of gravity to the first path.

Abstract: An apparatus for determining one or more optimal operating parameters for debarking wood is provided. The apparatus has a scraper and an actuator configured to adjust the position of the scraper toward a sample portion of the wood to scrape a surface of the sample portion of the wood with a scraping force. The apparatus also has a force sensor operatively associated with the scraper for detecting the scraping force. A light source impinges light on a scraped surface of the sample portion. A light detector detects a light image defined by light from the light source reflected by the scraped surface. A controller is operatively associated with the force sensor and the light detector. The controller has processing means to determine the one or more optimal operating parameters based on signals relating to the scraping force and signals relating to the light image. The one or more optimal operating parameters are relevant to debarking wood proximal to the sample portion.

Abstract: Method and device for delimbing a tree trunk (60) in a compliant gripping state defined by a set of limbing knives (18, 24, 26, 28) enclosing the trunk. The limbing knives are repeatedly adjusted through a control unit (46) for adaption of the gripping state to a varying thickness of the trunk when the trunk is advanced between the knives for the delimbing of the trunk. The invention comprises entering a desired compliance (D1) of the gripping state in the control unit (46), detecting an actual compliance (d) of the gripping state, and performing each adjustment of the limbing knives via the control unit until the actual compliance (d) corresponds to the desired compliance (D1).

Abstract: A method and an apparatus which defines the amount of wood material present in a bark flow and controls a debarking process on the basis of the data to reduce wood losses in the debarking process. In accordance with the invention, the bark flow is imaged by a camera and an image processing unit processes the image by using different whitenesses of the picture elements or pixels of the image as a basis for defining programmatically the amount of wood material in the bark flow. The image processing unit is adapted to produce an output signal for controlling the debarking process. In addition, the invention also provides a method and an apparatus which defines the amount of wood material in a bark flow being moved to a combustion process and controls the combustion process on the basis of the data.
