FIELD: wood industry.
SUBSTANCE: method comprises cutting timber in the plane passing through the centers of the top and butt. The shape and parameters of the core layer are determined in advance, and the timber is divided into sectors in the longitudinal direction in the planes passing through the centers of damaged layer at the top and butt. The sectors are divided into parts along the bisectrix of the sector angle. The parts are straitened by means of steam-softening and bending, are pressed, and, after drying, rotate by 180° with respect to each other in the vertical and horizontal planes. The worked surfaces are brought together and fastened.
EFFECT: enhanced quality of wood.
