METHOD OF MANUFACTURING SAWN GOODS FROM LOGS Russian patent published in 2009 - IPC B27B1/00 

FIELD: woodworking industry.

SUBSTANCE: method involves production of a two-edged cant and two segments from the central part of a log. Three-edged cants and sectors are sawn from the obtained segments. The height of the two- and threee-edged cants is H_cant=0.383·d_t, where d_t stands for the diametre of the top log cut. The sectors produced at the segments sawing are dried and milled at the log top diametre equal to d_t>0.22 m, lumber products with an isosceles triangle in the cross section are obtained and glued into square cants; at the diametre d_t≤0.22 m the sectors are milled into mouldings.

EFFECT: increased volume output of high grade lumber, reduced amount of waste and decreased power consumption.
