FIELD: wood-working industry, applicable at location and spacing of logs for lumbers. SUBSTANCE: after sawing-out of thin edge-unsurfaced lumbers from the side surface of the log it is turned around the axis by 90 deg. For sawing off of the next thin lumbers. A cant is obtained with two adjacent sawn-through sides. After that it is turned by 90 deg. And sawn into thin edge-unsurfaced boards and thick lumbers with one surfaced edge. Location and spacing of the log, cant into thin boards is carried out to a distance of 0.707 of the topped radius of the log from the center of the log end face. The thickness of thick boards is preset from the condition of equality or multiplicity to its width of thin lumbers. EFFECT: reduced waste of wood to edging and sawdust. 1 dwg
