Effect of moisture content and speed of cut on quality of rotary-cut veneer
U.S. Dept. of Agriculture, Forest Service, Forest Products Laboratory, 1967 - House & Home - 13 pages
Within the limits of the study, high moisture content in the wood and high cutting speed resulted in higher loads on the roller bar than when cutting wood having moderate moisture content at slow cutting speed. In general, veneer cut with high loads on the roller bar was thinner and weaker in tension perpendicular to the grain than veneer cut with moderate loads on the roller bar. (Author).
