METHOD OF PROCESSING SMALL-SIZED WOOD RAW MATERIAL TO BEARING-ENCLOSING ELEMENTS OF TWO-SIDED ASSEMBLY WALL BEAM Russian patent published in 2015 - IPC B27B1/00 

Abstract RU 2551103 C1

FIELD: woodworking industry.

SUBSTANCE: for obtaining bearing-enclosing elements of two-sided assembly wall beam the log roundup is carried out, then two parallel planes are created, and two-sided beam is divided by longitudinal sawing into two equal three-edge cants. Before the log roundup its debarking is carried out by removing the bark. The performs are separated from the rounded log by sawing for production of finishing boards. Along with the division of two-sided beam the longitudinal through grooves of semicircular cross section are made on bearing planes of the three-edge cants. Obtaining the three-edge cants provides a two-stage division of two-sided beam simultaneously on both sides to a depth sufficient to relieve internal stresses during drying, but with the possibility of leaving the jumper. The jumper enables to save the cross-sectional shape of two-sided beam for transportation. Final separation of the beams is carried out by the longitudinal sawing the jumper at the place of the assembly of wall beam. The chips and sawdust are collected in a separate hopper and shipped to the companies of pulp and paper production.

EFFECT: increased output of solid industrial wood, chips and bark.
