METHOD OF BEARING-GUARDING ELEMENTS PRODUCTION 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 warmth-keeping jacket and bearing-guarding elements of composite wall cant are sawn off. Bearing sites of guarding elements feature different width equal to 1/3 width of two-edged cant site. Simultaneously with production of bearing-guarding elements, edged-surface lumber its thickness making 1/3 of the area of two-edged cant site is made by sawing the mid part of said cant. 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. Every second solid element is screwed with lumber of similar cross-section.

EFFECT: higher yield of commercial timber.
