METHOD FOR CUTTING OF ROUND TIMBERS HAVING A PITHY ROT Russian patent published in 2007 - IPC B27B1/00 

FIELD: forest industry, applicable in production of sawn timber.

SUBSTANCE: the method consists in cutting of the timber in the plane passing through the centers of the top and butt. At first the shape and the parameters of the pithy layer are determined, the timber is divided into sectors in the longitudinal direction in the planes passing through the centers of the affected layer in the top and built; the sectors are divided into parts in the curvilinear generality line of the cutting tool having, for example, the shape of a cylinder, shifting the plane of division in the bisector of the sector angle; the parts are laid in stacks, rectification of the parts occurs in the process of hydrothermal treatment, for example, drying, after that the parts are turned through 180 deg relative to each other in the vertical and horizontal planes, the treatment surfaces are conjugated and fastened to one another.

EFFECT: enhanced output of qualitative timbers.
