FIELD: process engineering.
SUBSTANCE: invention relates to woodworking. In compliance with proposed versions, butt-ended logs are sawn into blanks with rectangular or square cross section, or, correspondingly, two or four isosceles triangles or trapezoids. Then said blanks red dried glued together by inclined sides, and, thereafter, they are sawn into two identical-width blanks to be glued together by their inclined sides.
EFFECT: wide range of processed log diametres, higher yield of timber and its quality.
