This project was carried out in three parts. Part one was to collect strands from commercial OSB mills and quantify how the strand shape mixtures found in the different mill samples impact OSBpanel properties. Part two quantified the impact of strand shape distributionon OSB production processes and panel properties. Part three, which is described in the this report, was carried out to determine whether relationships could be established between strand manufacturing condistions and strand shape. The reasoning behind the work was that if relationshiups could be established, strand shape factor could become a tool for OSB manufacturers to usein controlling strand quality and troubleshooting strand manufacturing problems.
