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 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. The bearing-guarding element entire surface composed of parts is cut to log-shape surface. At a time, edge-faced timber is cut from two-edged cant in thickness making 1/3 of two-edged cant while workpiece for finishing material is separated sap-wood side is separated from every second blank. One of two elements with preserved sap-wood side in sawn into two identical-height parts. Grooves are milled for insulant composed of sealant cord opposite the site with groove at parts of sawn element.

EFFECT: higher yield of commercial timber.
