Path-controlled press operation permits a cylinder movement that is technologically optimised with the loader’s and unloader’s cycle times tuned accordingly.

Finding out the unrealized potential through the use of weight per unit area gauges One of the most vital factors in the production of wood panels is the constant spreading of material. If tolerances are exceeded, higher material and energy consumption are the consequences. MSX, which constantly moves back and forth across the mat before it enters the hot press, maintains tolerances within the optimum range. The result is homogeneous forming in lengthwise and crosswise directions. The enormous technical developments of “Weight per Unit Area Gauges” of the past years are physically not visible. What are the previous limitations of weight per unit area gauges? The x-ray tube needed a cooling device. This resulted in a reduced lifetime. Electronic Wood Systems developed a detector with extremely high sensitivity – probably unmatched in the world. Due to this new detector the net power could be reduced to a small portion of the permitted power.

Fibre sifters are used for processing softwood and rubberwood bres. They serve to remove tramp material, glue clots or latex particles from the resinated and pre-dried bre ow. Only a meticulous preparation like that can ensure a homogeneous board surface without any stains. In addition, sifting is an eective protective measure for the steel belt in the subsequent pressing process. The sifter is fed from the top. Disintegrating rollers mounted in the feed chute loosen up and homogenise the bre ow. Air is introduced from the bottom. The calculated volume ensures that the acceptables, which are lighter, are conveyed upwards, while the heavier rejects drop downwards to be discharged via rotary air lock. The entire sifter and all its ducts and piping are calculated and optimised precisely to the bre ow. This enables the pressure losses to be minimised and the energy eciency of the sifter to be improved signicantly compared to other systems..
