METHOD OF BEARING-GUARDING ELEMENTS OF WALL TIMBER FROM SMALL-DIMENSION TIMBER STOCK Russian patent published in 2014 - IPC B27B1/00 

FIELD: process engineering.

SUBSTANCE: invention relates to woodwork, Log is rounded up and its end is milled to preset shape and separated by sawing. Then, grooves are cut at remainder two-edged cant for insulant and bearing-guarding elements of composite wall cant are sawn off. Bearing sites of guarding elements feature different width equal to 1/3 and 2/3 widths of two-edged cant site. Element with site width equal to 1/3 of that of two-edged cant site is sawn to two parts of equal height. Grooves are milled for insulant composed of sealant cord opposite the site with groove at parts of sawn element. Element with site width equal to 2/3 of that of two-edged cant site is sawn to two parts of equal to 1/3 of said cant. One of said parts is similar to guarding element with width equal to 1/3 of cant side width while second part is an edge-surfaces lumber. Lumber of identical cross-section is fitted instead of sawn off lumber and screwed in place at guarding element.

EFFECT: higher yield of commercial timber.
