What is the selitch?

Slitch is a beam of wood cut from a tree. Some robbers are transferred to thinner pieces for use in various wood processing projects and many of them are cut into very sharp blades for extremely thin slices called veneer. The inserts are also used in the construction to prepare luda rays. This creates a very strong beam that can be used in areas where a long, unsupported beam is required. The standards for the production of these rays are very demanding and charge not only for length, width and thickness of wood and steel members, but also for used wood species. For example, a beam of California sequoia is a bit stronger than the same beam made of Lodgepole pine. As a result, the construction of the sewn beams is very demanding to work and for this reason, when more varieties of engineering lumber, such as laminated veneer lumber (LVL), was easily accessible at the end of the 20th century, the popularity of Fastch Beams has fallen.

selitches used to produce robbers are straight cut from pine protocols; This means that the protocols are simply cut into long rays of the same thickness by log over the entire length. However, simple cutting distorts the appearance of a wooden grain, some of which of the cereal lines appear widely placed and others tighter. However, wood -sowers generally prefer uniform grain patterns and there are other ways to reduce protocols, such as their neighborhood around the center of the protocol that will produce boards and veneers with even grain patterns.

Veneers are very thin layers of wood, often not stronger than 1/8 inches (three millimeters), "peeled" from lusts with very sharp blades. Veneers are usually cut out of hardwoods such as oak, cherry, maple or more exotic species. MORE PLAIN PINE WOOD used to create a piece of furniture or cabinet, give the surface a more interesting or attractive look. The use of a saw for cutting veneer is discouraged by woods because this reason whyThe EC blurring the grain detail and also because a large amount of wood is lost on the saw. The veneers are usually chopped from the lusts by air machines that pass through the blades through paper robbers and shave very thin slices.
