The invention relates to methods and technologies intended for processing small-diameter unpeeled state of raw wood for the purpose of obtaining necesaarily of elements (NOE) in the form of a third side rail and bulk waste suitable for pulp and paper production (PPI), and can be used on wood processing enterprises and the enterprises of the construction industry.

Various methods of processing small-diameter unpeeled state of raw materials, particularly for wood chips for pulp and paper industry [Loggers N. M. Chippers, - M: Lesn. Industry. 1980, 96 pages]. Processing of the present method is carried out by small-sized timber debarking debarking on the machines and grinding chipper machine for wood chips for pulp and paper industry.

The disadvantage is that wood chips are crushed large volumes of coniferous wood of valuable breeds Siberian, such as cedar and larch trees that are becoming more popular in residential construction because of its unique properties.

Closest to the proposed is a method for processing of wood raw material for details for wood construction [Kovalchuk L. M. Production of glulam. 2-e Izd., revised and enlarged extra - M.: Lesn. industry. 1987, 247 S.], which consists in obtaining of logs by milling.

The disadvantage �of the textbook is its focus on the production of round timber only from raw materials of medium and large diameter, which is becoming increasingly scarce and therefore more expensive.

In recent years the construction industry begins to actively use three-layer construction of the walls of houses, such as "Lumber to build the wooden frame" [RU 77885 U1, publ. 10.11.2008. Bul. No. 31], in which the NOE are connected to each other by wooden bridges, and the space between the elements and vias filled with a filler, and in this structure, the width of the beam is greater than its height. Such design of the beam allows the use of small-diameter imported coniferous raw local organic fillers. And the use of different types of wood in one design, for example, outside - larch, and inside - cedar, gives additional environmental benefits houses, built of timber this design, and reduces the cost of their construction.

The closest to the proposed is a Method for processing of small-diameter wood raw material for the enclosing elements of the two-sided precast wall beams" [Application 2008123621/03, 10.06.2008. Publ. 20.12.2009], including cylindering logs, then milling two parallel planes, and division longitudinal sawing received a cant beam into two equal third side of the beam.

The disadvantage of this method is that the inten�and giving raw wood form of a cylinder subjected to small assortments without prior debarking, leads to get chips with a high content of bark. To separate this mixture into components (shredded wood and bark) requires additional equipment, and this leads to higher prices for products. Besides giving the original beam without debarking cylinder shape leads to a rapid blunt cutters for cylindrical shaping of logs of the machine and, consequently, to a decrease in performance associated with the change of knives on the milling heads. The important deficiencies must be attributed the fact that during the processing of assortment on NOE in the form of solid wood presents only two-sided cant, and everything else is shredded wood. And especially it should be noted that during the drying NOÉ on the outside will crack as a result of the removal of internal stresses in the wood due to the lack of compensation grooves.

The technical problem solved by the invention is to obtain NOÉ two-sided precast wall beams from thin wood raw material with a maximum output solid business Gresini, wood chips for pulp & paper and bark.

The technical result is achieved in that a method of processing small-diameter wood raw material on NOE two-sided precast wall beams, including cylindering logs, then create two parallel planes, and division cant beam longitudinal sawing into two identical�x third side of the beam, according to the formula of the invention, before cylindering logs produce debarking by removing the bark from logs by sawing separate blanks for the production of finishing boards, while simultaneously split a cant make timber longitudinal through grooves of semicircular cross-section on the supporting planes of the third side of the bars. The invention is illustrated by the diagram, which presents the execution order of processing operations unpeeled state of raw wood.

The order of the operations numbered:

A - unpeeled state thin wood raw material;

1 - barking;

2 - cylindering;

3 - Department of blanks for the production of finishing boards;

4 - cutting through longitudinal grooves and longitudinal sawing;

B - NOE two-sided precast wall beams.

The operations of the present method is as follows. The feedstock is in the form of unpeeled state small-sized timber And exposed the operations of debarking 1 by removing the bark and drain it into a separate hopper. Then debarked raw material attached to the form cylinder 2, from which, by sawing separate blanks for the production of finishing boards and reproduces the look of a cant bar 3 with two parallel surfaces. And then two-sided cant by longitudinal sawing 4 is divided into two equal third side of the beam 3 with synchronous�variable item by cutting longitudinal through grooves of semicircular cross section. The resulting bars are NOE two-sided precast wall beams B, but before they are subjected to a drying chamber, which reduces shrinkage of the framework and dimensions of the cracks visible on the surface due to compensation in the form of grooves longitudinal through grooves of semicircular cross-section (designed for securing of the cord dock shelter during construction). Chips and sawdust are collected in a separate hopper, and delivered to the enterprises of pulp and paper industry, and the workpiece is transferred to the shop floor to generate the block-house. The beam Assembly is the final step and is performed in accordance with the project of the future house.

The advantage of the proposed method is the manufacture of wall beams with improved characteristics in industrially from thin materials with a high yield of solid wood and reducing the cost of raw materials, reducing the cost and construction time, to improve the environment in the house.

Method for processing thin wood raw material on messeakademie elements two-sided precast wall beams, including cylindering logs, then create two parallel planes, and division cant beam longitudinal sawing into two equal third side of the beam, characterized in that before cylindering logs produce debarking by removing the bark from logs by pileni� separate blanks for the production of finishing boards, at the same time with split timber make a cant longitudinal through grooves of semicircular cross-section on the supporting planes of the third side boards, designed for fastening of the cord dock shelter during construction, with wood chips and sawdust is collected in a separate bin and shipped the enterprise of pulp and paper production.
