METHOD FOR LOCATION AND SPACING OF ROUND TIMBERS HAVING PITH ROT Russian patent published in 2005 - IPC

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

SUBSTANCE: the method consists in location and spacing of timber in the plane passing through the tops and butt ends, removal of the pith layer. First the shape and parameters of the pith layer are determined, the timber is divided into sectors in the longitudinal direction in the plans passing through the centers of the affected layer in the top and butt end. The sectors are divided into parts in parallel with the generating line on curvilinear surfaces in the plane of the fibers, the obtained parts are classified according to the geometric parameters and qualitative characteristics. The parts are turned relative to each other through 180 deg in the horizontal plane, the treatment surfaces are joined, then the parts are rectified by bending or pressing, fastened together at the same time. The fastened parts are pressed, and after pressing, are dried.

EFFECT: enhanced yield of qualitative product.
