Now maximising the efficiency for finger-jointing applications has now become easier with Opticut 450 FJ+ from Weinig. This high-performance optimising cross-cut saw is the ultimate solution for short-length processing with maximum accuracy and speed. The machine retains full control at the end of the board over short parts up to 110 mm, that are reliably separated from the waste and transferred to the sorting station.
The OptiCut 450 FJ+ was specially developed for finger jointing applications. The FJ model variant stands for Finger Jointing. It features a special feed system that reliably transports even the shortest workpieces. This allows the machine to maintain full control of short workpieces up to 110 mm at the board end, which are reliably transferred to the sorting system.
To achieve the required performance even with the shortest lengths, the OptiCut 450 FJ+ comes standard with the clever VarioSpeed feed system and the intelligently controlled high-performance waste chute. Individually suspended feed rollers from above, with HighGrip rollers specifically tailored to the wood type, deliver full power to the workpieces and position them precisely. To ensure precise positioning, the workpieces are fully measured lengthwise before the first saw cut. An additional non-driven measuring wheel in the saw ensures maximum cutting accuracy.
In addition to additional software solutions to optimise your production, various mechanisation solutions are available. OptiCut is designed according to a modular system that ensures someone well-equipped for the future. Appropriate extensions allow one to quickly respond to changing market requirements. Connecting scanners, OptiCut Stackers (for automatic stacking of preferred lengths), and/or expanding to multiple cross-cutting lines are no problem.
Finger jointing with WEINIG: for a strong connection
Finger jointing is recognised 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!
