Date Oct. 28, 1993.Sheets of wood are cut from a timber piece along a guide and against a cutting blade. A transverse taper of the wood piece is measured as the wood piece is conveyed. In accordance with changes in the measured transverse taper, the guide or the blade is pivoted about an axis extending perpendicular to the blade edge as the wood piece is being conveyed. Also, the longitudinal taper of the wood piece can be measured as the wood piece is conveyed. In accordance with the changes in the measured longitudinal taper, the distance between the blade edge and the wood guide is varied as the wood piece is conveyed.
