Finger jointing with WEINIG: for a strong connection

Finger jointing is recognized as the most stable method of creating length joints between two solid wood or wooden composite components. It is used in order to produce very long wood components or to separate out branches and cracks which lower the strength. Using finger joints it is possible to joint short pieces of wood into one, in principle, infinitely long strand of wood.

It is produced using a longitudinal joint with high initial force (self clamping), which is then always glued. As a result of the constant crossover between the two connected parts it also has a correspondingly high flexural strength. These characteristics mean that it is superior to steel-wood joints as well as other wood-wood joints. Finger jointed components can almost achieve the same strength as components grown in one piece, given the ideal conditions in terms of production and quality assurance.

Using WEINIG finger jointing technology makes residual wood processing and upgrading particularly profitable and easy for you!
