Product Description

Automatic Wood Finger Joint Machine

An automatic wood finger joint machine is a specialized woodworking machine that automates the process of creating finger joints in wood pieces. These machines are designed to cut and shape the fingers and slots with precision, resulting in strong and seamless joints.

Wood finger joint machine is mainly used for making finger shape of wood, smear the glue on the tenon,and then put into the finger jointingt machine to make the wood connect tight, then use the wood cutter machine to cut the wanted length.

Finger joints, also referred to as comb joints, are a woodworking technique where two pieces of wood are interconnected with interlocking finger-like projections. These projections resemble interlocking fingers when viewed in cross-section. To create this joint, complementary triangles or rectangles are cut into the two wood pieces, which are then glued together to form a unified piece. This method is recognized for its exceptional strength, as it generates a joint that is stronger than the wood pieces themselves.

Finger jointing is widely recognized as the most reliable method for creating long joints between two solid wood or wooden composite components. Its primary purpose is to produce extended wood components or to eliminate weak points such as branches and cracks that reduce overall strength. By employing finger joints, it becomes possible to connect short wood pieces into a single, seemingly endless strand of wood.

This technique involves a longitudinal joint that exerts substantial initial force, effectively clamping itself, and is always accompanied by adhesive bonding. The continuous interlocking between the two joined parts contributes to its exceptional flexural strength. These qualities make finger jointing superior to both steel-wood joints and other types of wood-wood joints. When produced under ideal conditions of production and quality control, finger jointed components can achieve nearly the same strength as solid, single-piece components.

Finger Joint Wood

Finger jointed wood are made from high-quality logs that have been kiln-dried. The ends of the wood are processed into finger-like shapes and bonded together using appropriate structural adhesives. While finger joints are used in various woodworking processes, including laminated wood horizontal joints, finger-jointed wood typically refers to standard-sized lumber.

The two main advantages of this product are straightness and dimensional stability. Due to the selection of stable short pieces of wood for joining, the product tends to be straight. With finger joints, the length of the wood is no longer limited to the size of the trees, and through manufacturing processes, we can produce beams and rafters of 12m (40′) or longer. Another advantage of this type of product is the ability to utilize short pieces of lower-quality wood, thus making more efficient use of forest resources. The finger-jointing process also helps eliminate wood defects, resulting in improved engineering properties of the product. Strict quality control is required during production to ensure the strength of the finger joints.

Technical introduction

Short-length wood joining techniques involve the use of end-to-end connections, where the processed wood pieces with the same tooth pitch and cross-section are glued together. Finger joints are commonly used in this process, offering several advantages such as cost-effectiveness and the ability to utilize lower-grade and short-length wood. By trimming the ends and planing the sides, the wood can be processed into higher-grade final products, including furniture, tabletops, and even structural products like laminated beams and I-beams.

There are two main types of finger joints: vertical and flat connections, or butt joints. These connections differ in terms of their appearance and the woodworking techniques involved. In vertical finger joints, the wide face of the wood serves as the visible surface, while in flat connections, the joint shape can only be seen from the side of the board. Vertical finger joints are popular in Europe and widely used in the production of structural beams in the construction industry.

For finger joints used in engineering structures, strict standards require them to have high tensile strength. Finger joints offer greater strength compared to large-sized solid wood pieces. Finger joints also find special applications in various value-added products, such as surface materials for doors, windows, cabinet components, aesthetically pleasing flooring materials, and furniture components.
