Press-Lam: Progress in Technical Development of Laminated Veneer Structural Products.
Abstract
The U.S. Forest Products Laboratory is continually seeking to provide technology for more efficient use of the wood resource, without increasing environmental pollution and energy demands. One of these research activities has centered on a processing system to produce a structural material, called 'Press-Lam', that is suitable for such items as beams and other structural members. Press-Lam promises an improvement in yield of dry product from logs, as compared to saving, in log-to-product times of less than 1 hour. The key to the speedy processing is the saving attained by press drying rotary-cut veneer up to 1/2 inch thick, and laminating the still hot plies into a continuous sheet. Estimated yield of structural product from logs between 12- and 28-in. diameters continues to appear to be between 56 and 66 percent. Large-scale yield studies are required to ascertain whether mill-run recoveries will be of this order.
