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.
