Abstract: A method of aligning lumber from which a first pair of cants has been removed to provide blocks for feeding along a sawing line before they are fed in the sawing line. The block is charged in a longitudinal direction to pass by the control device. The control device defines the block's side profile and outlines the even or sawed surface, after which the block falls on its side and is charged transversely against at least two adjustable stops, which have been positioned in a desired manner so as to ascertain an optimum amount of wood products at the next processing stage. The block always falls with the same side up so that the edge which was the upper edge while measuring the block's profile, is transferred transversely against the adjustable stops.

Abstract: System of transferring wane-edged boards through a control station for edging to detect the wane consistent and possibly other characteristics of the board automatically. The board is first aligned automatically by transporting each board separately and sequentially against a first group of fixed transversal stops to provide the same sawing line for each sequentially fed board; then each is moved sequentially from the transversal stops to and through a control station where the wane consistent and other features may be detected. The information is recorded in a data processing unit memory, and then the board is transferred to an edging station and aligned against a second group of transversely positioned adjustable stops. The movable stops are optimized on the basis of information supplied by the data processing unit based on quantities measured at the control station and other information so that each of the boards is transferred to the same sawing line.
