METHOD AND DEVICE FOR SAWING Russian patent published in 2006 - IPC B27B1/00 

FIELD: wood-working.

SUBSTANCE: the method consists in measurement or analysis of helicity after drying of the sawn blank and/or lumber obtained by sawing of the wood trunk, the wood trunk is sawn with an opposite helicity, compensating for the helicity after drying, the surface of the saw cut is turned around the trunk with a change of the angle (K) between the segment of the straight line determined by the sawing tools or by the edges of the sawing tools, and the reference segment of the straight line determined by the center of the trunk cross-section. The device has sawing tools and a device for tree motion, which includes a feeding device for tree motion, which includes a feeding device and a receiving device, it also has a measuring means for measurement and/or determination of the angles of inclination of the wood trunk grains and means for provision of the surface of the saw cut turned around the wood trunk with a change of the angle (K) between the segment of the straight line determined by the sawing tools or by the edges of the sawing tools, and the reference segment of the straight line determined by the central line of the wood trunk cross-section. Special different cases of realization of the method and device construction are described.

EFFECT: enhanced quality of lumber processing and reduced time of processing.
