Method and system of aligning lumber, especially blocks from which the first pair of cants has been removed

A method of aligning lumber from which a first pair of cants has been removed to provide blocks for feeding along a sawing line, said blocks having a base, sides and a top, comprising:

• using a control device having information to define a side profile of a block to examine the blocks which traverse thereby to calculate and to determine the optimal direction and position of the blocks with respect to the sawing line;
• moving each of the individual blocks on its base in a longitudinal direction to pass by the control device to permit the control device to produce an output characteristic for defining each of the individual block's side profile and outlining the even sawed surface;
• causing one of the individual blocks to fall on its side;
• providing at least two adjustable stops and adjusting the stops relative to the individual blocks side profile in response to the output characteristics of the block provided by the control device;
• and,
• transversely moving the block after it has fallen on its side against the at least two adjustable stops, the adjustable stops being positioned in a desired manner in response to information contained in the output characteristic so as to ascertain an optimum amount of wood products at a next processing stage in accordance with information obtained by the control device from the block.
