FIELD: construction.
SUBSTANCE: machine contains frame with two located in parallel longitudinal guides where trolley is installed. On the trolley bridge is rigidly fixed. The bridge is equipped with processing tools in the form of chain saws. To get longitudinal slot on raw log, two chain saws are mounted with their chain blades planes being parallel to log axis and opposite-directed under the same tilt angle to horizontal plane. Chain saws are attached to separate sliders located on corresponding bridge guides and interconnected with common horizontal actuator screw with possibility of synchronous counter or opposite motion. To process end locks of raw logs, the machine is provided with two additional trolleys with double bridges equipped with processing tools in the form of chain saws. Additional trolleys with double bridges are installed on opposite ends of frame guides.
EFFECT: invention improves timber processing quality and reduces labor consumption.
