Abstract: In the veneer cutting process, pressure bar force and the compressive deflections caused in wood play important roles, but few studies have dealt with the exact measurements of the deflections, and so, the main objective of this report is to obtain quantitative information on them. The clear specimens from Red-lauan (Shorea sp.) to which were applied thin sensitive films printed grid patterns with pitches of 0.280mm to the end-grain surface, were prepared. After being soused in water up to saturated condition, they were set on the experimental apparatus equipped with two-axis dynamometers mounted on a feeding carriage (Fig. 1). Then these test specimens were compressed or rolled out by various types of pressure bars in both stationary and feeding state of the carriage. The deflection distributions in the specimens were determined from the distortion pattern of grid lines (Figs. 2 ∿ 9).
