METHOD OF CUTTING LOGS Russian patent published in 2014 - IPC B27B1/00 

FIELD: woodworking industry.

SUBSTANCE: method of cutting logs comprises longitudinal cutting, removal bark from the core parts along the rise, drying, turning and connecting. Longitudinal cutting of log is carried out in parallel with two opposite generants to obtain shortened timber from the log central zone. In core parts obtained as a result of longitudinal cutting of several logs the edges are sawed parallel to the longitudinal axis. After drying and additional processing the obtained semiproducts are turned relative to each other by 180° and connected in a beam. The core part of round timber obtained as a result of longitudinal cutting is turned by 90° and cut into timber of alternating rectangular cross-section. After drying and additional processing the timber of alternating rectangular cross-section is turned to each other by 180° and connected to the shield along the edge. In the uncut timber the bark is removed along the rise at an angle to the sawn wood faces, they are turned by 180° relative to each other and interconnected along the edge to the shield.

EFFECT: reduced amount of wood waste.
