Classic glue-blending systems in blowlines reach their limits when special glue systems need to be applied to bres. It is therefore not possible to apply glues that respond sensitively to higher temperatures before the dryer. Chute glue-blending systems constitute the answer to this challenge. This type of glue-blending system is used, for example, in the insulation-material industry

The light-board package consists of a special cylinder conguration with additional double-acting cylinders. Its concept enables the production of especially light engineered boards still comfortably within precise and tight thickness tolerances. Since light boards can be produced at specic pressing forces below the hot platen weight, the upper hot platens must be lifted by double-acting cylinders. When the light-board option has been installed, there is an abundant number of double-acting cylinders distributed across the hot platens to prevent any hot platen bending, thus maintaining the requested board thickness. Features Additional dierential cylinders operating as double-acting cylinders Additional hydraulic control circuits to enable precise control of the dierential cylinders. Advantages

The hydraulic hot presses have been dimensioned in such a way that they are able to exert and evenly distribute a specic pressure of at least 400 N/cm² on the product. Features, function The loader takes up the pressing batch at the transfer station. The previous nished board is removed from the press and the new press batch is transferred into it. The subsequent pressing time depends on the resin's reactivity, the selected pressure and the set temperature Advantages The press uses a multi-cylinder design that, with the pliant hot platens used, permits the specic pressure on the product to be set very precisely. 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.

The first examples of which were built by CMC TEXPAN in the early 1990s.They are aimed at cleaning the material ow fed into the machine byremoving any possible contaminants, the density of which is higher than that of the processed wood chips, e.g. stones, sand, metals, rubber, coarser chipsetc.The principle of operation is based on densimetric separation chieved in a vibratory box. In addition to the vibration of the machine casing, the materialow is subjected to a strong, pulsating air ow, enhancing the separationeect and providing for further “dry leaning” of chips. Heavy contaminants (e.g. stones, glass, rubber and plastic) are removed from the material ow,discharged from the machine side and conveyed to further re-classication,while clean chips are discharged from the machine’s front end.

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..

Siempelkamp's continuous saws are a tried-and-tested solution for plants with highest outputs. The saw throughput does not depend on the number of cuts and is therefore superior to other cutting solutions, particularly for large master boards. Continuous saws also permit in-line quality grading. This means that the combined sanding and saw line is able to deliver sorted stacks of nished boards from the master boards in a single stage of work. This allows investment and operating costs to be minimised. The cut-to-size saws may be combined in-line with a sanding machine or set up separately just as a cutting system Features and functions Continuous saws for longitudinal and horizontal cuts Scoring unit and main saw blade for top-quality edges Reliable guiding of the board using chains and/or rollers to ensure accurate cutting Trimming of the edges directly by the tool, no additional conveyors and follow-up work required

Siempelkamp has developed the energy-ecient drive system EcoDrive for the ContiRoll® main drives. This system meets tomorrow’s legal and standard demands on the energy eciency of drive systems already today. It comprises frequency converters, motor and gearbox - all well-tuned to one another. In addition to the energy eciency our R&D-work focussed on an improved precision and controllability of the entire drive system. The focus is on high belt speeds, precise r.p.m. for a synchronous operation of the steel belts, torques adjusted to the characteristic load line in connection with the hydraulic pressure/position control, good performance, good uptimes and ease of maintenance. This corresponds to the demand on a very high product quality and an on-demand energy consumption even in partial load operation. This new drive system is able to save more than 10 % of the electrical drive energy compared to traditional Solutions.

The EcoPulser by Siempelkamp uses a completely new almost wear-free, bladeless process to achieve an additional size reduction of chips and particles. Shock waves, generated by interferences of wavefronts aect the bulk material by breaking up its structure. Even the most abrasive particles can be processed using this non-contact treatment because the particles are broken up in the air. The EcoPulser disintegration bases on two counter rotating impeller wheels, which generate by their fast rotation extreme air oscillation and negative pressures. This air current takes in the chips or particles through the rotor so that their wood cells lled with air, water or ice tear apart by the negative pressure impact with the bres separating along their grain. The length of the wood bre nearly remains unchanged thus ensuring a higher board stability

Wind formers convey especially ne particles to the top faces, thus creating ne board surfaces. This is because ner particles are conveyed much farther in an air ow than coarser ones. The forming system of a particleboard line usually comprises two wind formers located at its front and rear ends, as they form the top and the rear board surfaces. The ecoFormer SL by CMC Texpan has been developed from the traditional wind former technology. This was because we wanted to improve the separation of coarse and nes particles to create the optimal board surface. The air ow was simulated using the CFD method (Computational Fluid Dynamics) and optimised with respect to its aerodynamic behaviour thus improving its energy eciency. The ecoFormer SL can also be easily retrotted into existing mat formers, since its outer dimensions are compatible with the conventional wind formers oered by CMC. Features, function
