Wood drying (also seasoning lumber or wood seasoning) reduces the moisture content of wood before its use. When the drying is done in a kiln , the product is known as kiln-dried timber or lumber , whereas air drying is the more traditional method.
A sawmill (saw mill, saw-mill) or lumber mill is a facility where logs are cut into lumber. Modern sawmills use a motorized saw to cut logs lengthwise to make long pieces, and crosswise to length depending on standard or custom sizes ( dimensional lumber ).
A process for steam straightening and kiln drying lumber, (1972). [10] A method for producing parallel laminated pine lumber from veneer, (1975). [11] A helical flaking head with multiple cutting circle diameters for milling lumber, (1977). [12] A system for burning green bark to produce heat or power in sawmills, (1977). [13]
The NHLA has a long history of being involved in the national and international issues that affect the hardwood lumber industry. In 1976, the hardwood lumber industry was concerned with the long-standing practice of the footage as an allowance for shrinkage in lumber measured after kiln drying. This practice was challenged as being misleading ...
Rubberwood has a dense grain that is easily controlled in the kiln drying process. Rubberwood has very little shrinkage, making it one of the more stable construction materials available for furniture, toys, and kitchen accessories. It is easily worked, and takes on stains uniformly. As with all hardwoods, rubberwood comes in varying degrees of ...
The drying process varies on the species of lumber, but can be done in as little as a week. Once the drying process is complete the planks are sent through a surfacer (or planer), which makes the face of the lumber perfectly smooth. These planks travel to a machine, which then spreads a special glue on the interior boards.
Apart from structural wood preservation measures, there are a number of different chemical preservatives and processes (also known as timber treatment, lumber treatment or pressure treatment) that can extend the life of wood, timber, and their associated products, including engineered wood. These generally increase the durability and resistance ...
The portable mills can cut lumber with speed and accuracy, though the subsequent steps of planing and drying must still be performed to produce finished lumber. Commodity lumber in standard sizes can be made this way. The more common use, however, is in the production of specialty timber products not readily available through lumber yards.
