FIELD: woodworking industry.SUBSTANCE: roundup of log, making longitudinal semicircular laying groove, cross-cutting of rounded log is carried out. Then the log is sawn into segments and the boards, which side surfaces are oriented parallel to the plane of symmetry of the workpiece passing through the middle of the longitudinal semicircular groove. The longitudinal cutting of the log is carried out along the symmetrical planes which are located at a distance of (0.25-0.5)·R from the plane of symmetry of the workpiece, wherein R is the radius of the log.EFFECT: increased volumetric beneficial yield of decorative lumber when cutting logs of various diameters.3 cl, 13 dwg |
