Verfahren und Vorrichtung zur Bestimmung einer Dichteverteilung in einer Holzwerkstoffplatte

The method involves recording a narrow side (2) of the wood panel (1) with a camera device (4) after compression in a continuous hot press. The images acquired by the camera device are evaluated based on the thickness of the wood panel. The density distribution in the dissolved layer is determined by the thickness of the wood panel. The lighting device (5) and the camera device are arranged in a constant orientation to each other. An independent claim is included for apparatus for determining density distribution in wood material plate. USE: Method for determining density distribution in wood material plate. ADVANTAGE: The density distribution of the wood material plate is calculated effectively, so that quality of wood-based panels is ensured made. The production efficiency of the wood-based panel is improved effectively. The variance in the apparent densities is reduced effectively. The gray value distribution of apparatus is less expensive. The quality of the recordings is improved effectively. The structure of the wood material plate is simple, so that manufacturing cost of the wood material plate is reduced effectively. The drawing shows a perspective view of the wood material plate. 1 : Wood panel 2 : Narrow side of wood panel 3 : Main surface of wood panel 4 : Camera device 5 : Lighting device.
