Abstract
Oriented structural board (OSB) is a wood-based material made from wood particles with a certain size and shape: The "natural" stiffness of the strands together with their size and orientation is utilized to produce boards with a low glue content but with a good MOE (modulus of elasticity). Strand geometry, influenced by the flaking process, and strand orientation and homogeneity during mat forming are crucial quantities which determine the board quality. Wilhelm-Klauditz-Institut (WKI) already reported on automatic strand geometry measurement and assessment (see Asian Timber March/April 2005) and detection of density variations in the board using thermography (see Asian Timber Nov(Dec 2005). This article deals with a development ready for use to assess mat quality on-line between the forming station and the press.
