METHOD OF CUTTING ROUND TIMBER WITH CENTRAL ROT Russian patent published in 2006 - IPC B27B1/00 

FIELD: timber industry; production of lumber.

SUBSTANCE: proposed method comes to initial determination of form and parameters of core layer, division of timber into sectors ion longitudinal direction in planes passing through centers of affected layer in top and butt. Sectors obtained after definition of form and parameters of core layer and division of timber are subjected to steaming. Sectors are divided into parts parallel to generatrix over curvilinear surfaces in plane of fibers, parts are straightened out by bending or pressing and then parts are turned relative to each other through 180° in vertical and horizontal planes, surfaces subjected to treatment are mated and fastened to each other and are glued together after drying, then connecting members are made in parts and parts are sorted out according to geometric parameters and quality characteristics.

EFFECT: increased output of quality products.
