O folheado é uma folha fina de madeira produzida com uma espessura de aproximadamente um oitavo de polegada ou menos.
Posicionando uma tora em um torno grande e girando-a contra um longo fio de faca, uma tira contínua de folheado é gradualmente removida à medida que a faca penetra firmemente na tora, resultando em um folheado de corte rotativo.
Plain-slicing, quarter-sliting, e rift-sliting são outros métodos usados no processo de folheamento.
O corte do folheado começa com a preparação de uma parte de um tronco, conhecido como flitch, por meio de serragem.
A trava é então fixada horizontalmente com segurança contra uma estrutura móvel resistente.
Uma faca de folheado, também montada horizontalmente, é colocada ao lado do fitch.
A cada movimento descendente da estrutura, a trava é forçada contra a faca, resultando em uma fatia de verniz.
Após cada movimento ascendente, a faca avança em direção ao flitch pela espessura de uma fatia de folheado. Cada folha é tão larga quanto a seção do fitch.
Painéis finos, armários, pisos de madeira, fabricação de móveis e fabricação de produtos de madeira são usos comuns para folheados.

folheado

Veneer

Folheado se refere a uma folha fina de madeira, normalmente produzida com uma espessura de cerca de 3,18 milímetros ou menos. Este material é criado por vários métodos, sendo o mais comum o corte rotativo. Neste processo, um tronco é montado em um torno grande e girado contra uma lâmina de faca, descascando uma tira contínua de madeira conforme a faca penetra mais profundamente no tronco rotativo, criando um folheado de corte rotativo.

Outras técnicas de folheado incluem fatiamento simples, fatiamento em quartos e fatiamento em fenda. Esses métodos começam com a preparação de um segmento do tronco chamado flitch, que é serrado no tamanho desejado. O flitch é então fixado horizontalmente contra uma estrutura móvel. Adjacente a isso, uma faca de folheado horizontal corta o flitch conforme a estrutura se move para baixo, produzindo uma folha fina de folheado. Após cada fatia, a faca avança mais perto do flitch pela espessura de uma fatia de folheado, garantindo espessura consistente em todas as folhas.

Os folheados são amplamente utilizados em várias aplicações devido ao seu apelo estético e versatilidade. Eles são comumente utilizados em painéis finos, armários, pisos de madeira, fabricação de móveis e na fabricação de outros produtos de madeira. Esses usos destacam a capacidade do folheado de fornecer um acabamento de madeira desejável, ao mesmo tempo em que maximiza a utilidade da madeira ao minimizar o desperdício.

how veneer is cut and used

Veneer is a thin sheet of wood that is usually about one-eighth of an inch thick or less. It is made to show the look of wood while using timber more efficiently. Veneer is common in furniture and other finished wood products.

One common way to make veneer is rotary cutting. In this method, a log is mounted in a large lathe and spun against a knife edge. As the knife moves deeper into the turning log, it peels off a continuous strip of wood. This creates rotary-cut veneer.

Other veneer methods include plain-slicing, quarter-slicing, and rift-slicing. These techniques begin with a log section called a flitch, which is sawn to the right size. The flitch is fixed horizontally on a movable frame, and a horizontal veneer knife slices through it as the frame moves downward. After each cut, the knife moves closer by the thickness of one veneer sheet to keep the sheets even.

Veneer is used in fine paneling, cabinetry, wood flooring, and furniture making. It is also used in the manufacture of other wood products. These uses show why veneer is valued for its appearance, versatility, and ability to reduce waste from timber.

introduction to wood

Wood Structure and Uses in Building

Wood is a construction material made from trees. A tree trunk has several layers. The outside is a protective layer of dead bark. Under that is living bark, then the cambium, then sapwood. As sapwood matures, it becomes heartwood. The pith sits at the center of the trunk. The age of a tree can be read from its growth rings. These rings are concentric bands seen in a trunk cross-section. Wood strength also depends on grain. Grain refers to elongated, tubular cells that run along the length of...

Wood Grain in Softwoods and Hardwoods

Softwoods and hardwoods come from different kinds of trees, and their leaf structures and cell makeup help explain how they are used. Softwoods come from cone-bearing trees with needle-like leaves. Hardwoods usually come from trees that shed broad leaves seasonally. Softwoods are made mostly of long cells called tracheids and a smaller number of rays, which are radial cells. This simpler structure gives softwoods a rougher grain. Because of this, they are often used in construction for...

lumber

Lumber Cutting Methods

Lumber is made from logs that are harvested, debarked, and processed into long pieces with a rectangular cross-section. The process starts when an automated saw slices a log into slabs. Those slabs then move on a conveyor belt to smaller saws, where they are cut into square-edged pieces of specific widths. Freshly cut lumber usually has rough surfaces. Its dimensions may also vary slightly from one end to the other. The way wood is cut affects both the lumber’s appearance and how it is used. <br...

Wood Strength Tests and Lumber Sizes

Wood strength depends on how its fibers are aligned along the length of the tree. This alignment gives wood much greater tensile strength along the grain than across it, sometimes up to twenty times higher. Wood also tends to perform better under compression than under tension. Fiber length varies by wood type. Hardwoods have fibers about one twenty-fifth of an inch long. Softwoods have longer fibers that range from one-eighth to one-third of an inch. Laboratory tests help measure how wood...

seasoning of wood

Wood Drying for Stronger Construction

Seasoning of wood is the drying process used to lower and stabilize moisture content before wood is used in construction. Fresh wood can swell when it takes in moisture and contract as it dries. Seasoning helps reduce that movement so the wood stays more stable after it is built into a structure. The main goal is to reach equilibrium moisture content. This is the point where the wood’s moisture level matches the moisture in the surrounding environment. When wood is seasoned properly, it is...

wood surfacing

Wood Surfacing for Smooth, Safe Lumber

Wood surfacing smooths lumber, improves its size accuracy, and makes it safer to handle. It is a key finishing step in woodworking and construction. The process also helps correct small distortions that can form as wood dries. Before surfacing, the wood may be sized slightly larger to account for shrinkage during seasoning, which is the drying stage. A plane, a tool with rotating blades, is used to remove material and smooth the surface. The same tool can also round the edges a little, which...

lumber defects

Common Wood Flaws in Lumber

Lumber defects are flaws in wood that can change both its appearance and its strength. These defects come from tree growth and from the way lumber is processed. Knowing the main defects helps explain why some boards are better for construction and manufacturing than others. Some defects begin in the tree itself. Knots form where branches were once attached to the trunk, and knotholes appear when those knots fall out. Decay and insect damage are also natural defects that can weaken wood and...

wood fasteners

Wood Fastener Types and Uses

Wood fasteners connect parts of a wood structure and help keep members in place. The strength of the connection depends mainly on direct bearing between the wood members. Different fasteners are chosen for different jobs and structural needs. Nails are the most common wood fasteners. They are sharp-pointed metal pins that are driven into wood with a hammer or a mechanical nail gun. Nails come in many diameters, head styles, and lengths. Nailing methods also matter. Face nailing places the...

Engineered Wood Products in Construction

Engineered wood products are made from wood strands, veneers, lumber, and even waste wood shreds. They are used in both structural and nonstructural building applications. These materials are designed to improve strength, durability, and versatility in modern construction. Glue-laminated wood, or glulam, is made by bonding several smaller pieces of dimensional lumber with adhesive. Cross-laminated timber uses solid lumber panels with layers placed so the grain direction alternates. This layer...

Types of Wood Panels in Construction

Wood panels are common construction materials used for flooring, siding, and roofing. They usually come in standard 4-foot by 8-foot sheets. Their thickness can range from one-quarter of an inch to one and one-eighth inches. Plywood is one of the most familiar wood panels. It is made by gluing thin wood veneers, or layers, under pressure. The outer veneer grain runs lengthwise, while the inner layers run widthwise. Plywood also has an odd number of layers, which helps keep the panel...
