Abstract
This report presents the results of the first stage of an investigation into the feasibility of developing a machine capable of automatically tensioning a bandsaw blade. The present work involves an experimental and analytical investigation of the effects of roll tensioning upon the cutting performance of the bandsaw. In order to understand the role of roll tensioning its effects on internal stress distribution, torsional and lateral natural frequencies and stiffness of the blade have been investigated. The results of strain measurements induced during different rolling patterns and with different thickness of plate and differing rolling pressures are presented and an analytical explanation of the results is given. Experimental results showing how the stiffness of the blade and its natural frequencies are affected by the roll tensioning are also presented. An accurate analytical model that relates the rolling pattern to the lateral stiffness has not been found. Cutting tests have been conducted in which the performance of a blade with no tension is compared with a blade with different levels of tensioning. The results of these tests are presented and indicate that the relationship between cutting accuracy and tensioning is very subtle.

Abstract
Forintek has developed a sawmill profit improvement program for mills in western Canada. A team of Forintek specialists work in cooperation with sawmill management to identify short-term low-cost improvements that can be made to current operations, and to identify the need for additional studies required to justify changes to equipment and processes that would achieve future profit improvement. Key areas included in the evaluation are sawmill processes, saws and sawing, kiln drying and lumber protection. The mill evaluation begins with documentation of known operating characteristics such as timber resource, sawmill design and maintenance, kiln design and control, and lumber drying schedules. The Forintek team visits the sawmill to evaluate current operating practices with the mill staff responsible for each aspect of the operation. Findings are discussed and a report is provided. This paper describes the sawmill evaluation process and provides examples of observations and recommendations made following three case studies. In all three case studies, significant improvements in mill operations could be made at very little additional cost

Abstract
The new technologies, incising, moisture tolerant phenolic adhesives and steam pressing were evaluated for the manufacture of laminated veneer lumber (LVL). Both 8- and 13-ply incised spruce LVL panels were prepared using these new technologies. The results showed that both steam pressing and self-generated steam from wet face and back veneers accelerated temperature rise in the innermost glueline of 13-ply incised spruce LVL panels. This would help facilitate faster production rates for LVL manufacture. Bond quality and edge bending values were determined for the steam-pressed 8-ply and 13-ply incised spruce LVL panels. In all cases the average % wood failure was above 90% indicating excellent adhesion between the moisture tolerant adhesive and wood. The modulus of rupture and modulus of elasticity values measured for the steam-pressed incised spruce LVL samples compared very favourably with those for a commercial Norway spruce 15-ply LVL product.
