WOOD PROCESSING AND CUTTING METHOD Russian patent published in 2008 - IPC A01G23/02 A01G23/81 A01G23/83 

FIELD: log processing and conversion.

SUBSTANCE: method involves clamping tree; cutting-off lateral branches and crown; performing barking and horizontal cutting of standing trees, with cutting procedure being performed simultaneously with barking and grinding procedures by drawing through grinding device beginning from tree butt-end and upward; bunching mixture resulted from grinding procedure; notching barked tree in butt-end zone at four sides so as to form base of square section corresponding in size to bar product section; removing notched segments from four sides of tree by performing vertical motion of saws; thereafter separating resultant bar from butt-end; dividing into cuts of predetermined length parameters and individually bunching resulted logs according to designation and sizes. Before or after manufacturing of logs, extracting stumps and grinding or removing from tree growing zone. Method allows ecological situation in wood processing zone to be improved by converting part of waste wood into saw wood and construction or fuel materials, and felled forest to be recovered.

EFFECT: reduced wood losses and waste, improved quality of sawn timber, increased versatility of wood logging procedure, reduced consumption of power and time for wood processing and reclamation by combining a number of procedures and using small-sized maneuverable technique.
