Sawmill

Logging industry – it is a complex, which includes logging and primary processing. Sawmill allows to automate the job of wood processing, improve productivity and quality, reduce the burden on the workers. The use of new techniques and coordination of work of all staff makes the modern sawmill profitable and enhances their competitiveness in the timber market.

Patrimony

Logging – hard work. Before there were the first sawmill, sawing wood or dissolution was made by a saw and two sawyers. This cutting required a lot of effort, but the quality of the board depended on the guide sawyer, who directed the tool carried by the line.

The oldest sawmill worked on a hydraulic actuator, or a waterwheel. The reciprocating movement therein through rods and transmitted to gear 2 saw frame. Such schemes sawmills were found in the ancient Turkish city of Hierapolis. Similar sawmill, driven by a water wheel without gear used in the Byzantine Empire. In Europe, the mills were in widespread use in the 16th century. In our territory, they appeared relatively recently – three hundred years ago.

The sawmill was arranged near the river, which gave the water to the water wheel, and much less – in place felling. Basically it was built on the lower or middle of the river, through which the alloy wire forest or transshipment to other vehicles. Wood contacted in rafts, raft raftsman to the sawmill.

Stages of the sawmill

Harvested (sawn) timber on plots where conduct random or clear cutting, cleared of branches and into the upper storage timber in the form of whips, and then transported by tractor, trucks or narrow-gauge logging sawmill warehouse. Sometimes the logs are divided into dimensional assortments and fused along the river by river barge or rail, to the place of its application.

In the sawmill timber arrives without drying, with natural moisture and joinery it is not suitable. In the sawmill, he is placed on a rack, and then placed on a trolley on the rails and is supplied to the sawing where it cut to sleepers, logs, planks, beams and carriages.

Used for joinery timber, after primary processing and cutting, it is placed on the warehouse site for natural drying or in special drying chambers. In the sawmill, logs are cut into metered parts of different sizes. After that, they are ripping on the machines – tape or circular. Modern Packet file machines, which cut occurs by means of circular saw blades, greatly accelerated the process of sawing logs.
