METHOD FOR LOCATION AND SPACING OF BLANKS OF ROUND TIMBERS HAVING A PITCH ROT Russian patent published in 2004 - IPC

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

SUBSTANCE: first the shape and the parameters of the pitch rot 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 in the butt end. The sectors are divided into parts of parallel generating line on the curvilinear surfaces in the plane of fibers. The parts are straightened by means of steaming and bending or compaction, after that the parts are turned relative to one another through 180 deg. In the vertical and horizontal planes. The surfaces of working are conjugated and fastened to one another. After drying gluing together of the parts in the edge is probable. Connecting elements are made to strengthen the joints in the obtained parts. To obtain products of different dimensions in thickness and quality, the obtained parts are classified according to the geometric parameters and quality characteristics.

EFFECT: enhanced yield of qualitative products.
