It is of vital importance that the oriented mat be conveyed precisely from the forming line into the infeed head of the ContiRoll®. Otherwise a dependable production process and a symmetrical heating of both surfaces could not be guaranteed. We therefore use an intermediate belt, which is perfectly tuned to the exible infeed head of Siempelkamp’s ContiRoll® and which adjusts automatically to the respective recipe and process Parameters. Features Basic frame including belt drive Belt tracking unit Tensioning device Motorised slide table, swivelling and moving in production direction Pulley unit Advantages Preassembled unit, modular design integrated in the forming line Positioning of the slide table in the press infeed in dependence on the recipe Options Belt cleaning brush Seamless, endless belt

It is possible to reliably remove reject boards without aecting the cycles in the rejects area. Acceptable boards continue to be transported towards the cooling turner. The rejected board stack may optionally be equipped with batch and package forming systems. These are for optimising the cooling turner utilisation and are explained in greater detail in the chapter about the ‘Cooling section’. The rejected board stack is equipped with a variable length adjuster or board lifter for the batch and package forming options. Reject boards are removed by lifting the rst belt conveyor. The rejected board stack may be optionally equipped with a buer for forming the reject stacks or with an additional belt conveyor that transports the rejects to the board breaker.

The high-rack store is primarily for linking board production with the downstream processing systems. Formatted raw-board stacks from board production and boards with papers for board lamination are stored intermediately in the high-rack store and delivered to the downstream systems as required. The high-rack store may be installed separately or combined with complete transport systems for connection to the production systems. Tailored to customer requirements, the high-rack store is designed with all the components needed for storage / removal and connection to the production facilities. Our goal: to achieve the best product in all forms through the optimum use of resources! The machines used are tailored in the best way possible to the products, the required capacity and interactions. It is possible to take account of extension stages from the start. Advantages Optimum use of space Safe and gentle material transport

We have developed the Siempelkamp press extraction systems especially for ContiRoll® presses and adjusted them to the particleboard, MDF and OSB production plants. Being a manufacturer and supplier of ContiRoll® presses, we are able to suit the extraction systems to our presses. We have been able to trace the emission sources thanks to our experience gained from the commissioning of almost 300 ContiRolls® over the past 30 years. Consequently, we have developed special extraction systems, which are generally able to extract the fumes direct. The concept results in a signicantly improved air quality in the vicinity of our presses as well as in the production hall. Moreover, the emission of solids resulting from the technological process have been localised accordingly and are collected by specially developed extraction hoods. This results in an excellent system uptime.

The ContiTherm is the optimally suited for the production of wood-based insulation material, the wood bres being preferably resinated with PMDI or thermoplastic melts. A steam/air mix is conveyed through the bre mat. During this process, the steam condenses at the bres or particles, heating them up. At the same time the gap between the upper and the lower hot platens is precisely maintained. This is essential for the production low-density boards of up to 250 kg/m³ approx. which exhibit outstanding thermal insulating propertie The dew point of the steam/air mix - thus the mat temperature - can be precisely set by varying the steam content. T sections (seen in working direction). Depending on the application these sections are designed for a unidirectional o with hot platens heated by thermal oil. The width of the steam boxes in an MDF-plant can be extended by additional segments to optimise steam-air conve

The EcoResinator is particularly suited to full the specic demands that are made on the technology employed for the glue-blending system used to manufacture MDF. Siempelkamp has equipped the EcoResinator with Schlick two-component nozzles. The second component that is used with the glue is steam. The size of the glue droplets is set with the help of the steam pressure and quantity. The corresponding parameters required for achieving the best possible application of glue based on the breboard's density are stored in the program. The optimised gluing methods may either be used to improve strength with the same amounts of wood and glue o and bres while preserving the same strength. The EcoResinator can potentially save up to 15% of glue over classic b recommended for all MDF plants. The EcoResinator also oers benets when existing plants are modied at a later point in time. The glue-blending sy within 24 hours.

CMC TEXPAN's roller separators are very suitable for processing fresh and recycled wood; they oer high performance when processing wet or semi-wet wood materials. Their principle of operation is based on the rotation of a group of rollers provided with a specic prole or disc pattern; they are adequately spaced apart, whereby such spacing denes the particle size selected. The material is bouncing on the rollers to separate the fractions. Particles of a size smaller than the gap between the rollers pass through the roller spacing. Larger particles are conveyed by the rollers and discharged. The size of the desired fractions can be simply adjusted by changing the gaps between the rollers and/or by using rollers with dierent patterns. "SRD" type - for pre-crushed material "SRU" type - for all typical applications and numbers of fractions "SRO" type - for wet or dry strands

The density of the material fed to the mat formers as well as the weight of the formed mat are important factors and must therefore be continuously monitored. CMC TEXPAN's load-cell scales can easily be tted into new or existing production lines to ensure consistent PB, MDF or OSB qualities. They can be installed inside metering bins to control the density of the material fed to the mat formers or downstream of mat formers to control the weight of the formed mat. The core of a mat scale is its weighing table, made of aluminium and split into two halves each connected to the relevant load cells by means of weighing levers. Mat scales operate in "load" mode that is to say the heavier the weight on the scale, the higher the load on the cells. The weight detected by the load cells will be displayed on a digital amplier, shielded against high and low frequency noise, which will give an mA-output signal for further processing in a PLC.

We will develop the mixing process that is best for the mix of glue that the customer is working with and deploy static mixers, dynamic mixers or tank-mixer systems.

Benets of accurate moisture control Moisture measurement is one of the most-important parameters for ecient panel board production. A moisture content in raw material that is too high results in a slow-down in production speed with an increased risk of causing blows, if raw material becomes too dry excess energy will be consumed. Also the risk of re and explosion in the dryer is greatly increased. If moisture is monitored at dierent locations within the production process, valuable information will exhibit for optimization of the process. Multi-wavelength infrared light is used which is targeted to, and reected by the material surface. A certain wavelength of infrared light is absorbed by water molecules, thus more or less weakened. The weakened signal is compared to the unweakened signal. The resulting values indicate the Visualization-PC Material collector for drop chute applications (e.g. after dryer) Measuring through glass window (e.g. silo, bin, screw conveyor) moisture content Technical Data Technology:Infrared Materials:Fibers, particles, OSB-strands Results:O.D.

Various heater types available, eciency and robustness characterise directly heated drum dryers by Büttner. They are used for drying wood particles, strands, sugar beet pulp and all free-owing types of wood, biomasses and bulk solids Features Water evaporation capacity of up to 80 t/h depending on the product Direct heating system with multi-fuel burners in combustion chambers Direct heating system using ue gases from energy plants Direct heating system using waste gases from turbines or engines All combinations of these types of heaters are possible. A ash tube may be used for pre-drying and oversize separation of material that is quite moist. Material separation via cyclones or drop boxes Function The material to be dried is admitted through an air-tight rotary air lock into a rotating single-pass drum dryer. The dryer drum can be tted with specic internal ights to suit the material to be dried. This results in an increase in surface area and thus an increase in eciency

Using a ContiTherm preheater upstream of the ContiRoll® press increases the production output of a wood-processing plant signicantly. It is an additional component integrated into the forming line and serves to preheat the mat before it is transferred to the ContiRoll® infeed to just below the temperature at which the glue starts to cure. A steam-air mix is conveyed through the mat. During this process, the steam condenses at the bres or particles, heating them up. The preheating temperature can be set most accurately by varying the steam content of the mix. The machine is separate into two to four sections (seen in working direction). Depending on the application these sections are designed for a unidirectional or a bidrectional steam injection or equipped with hot platens heated by thermal oil. The width of the steam boxes in an MDF-plant can be extended by additional segments to optimise steam-air conveyance.

Drum chippers are used to process long and short logs, wood pieces, saw mill waste, veneer waste, residual wood, and other wood waste to high-quality chips. Depending on the size and design of the drum chipper, the machine can be adjusted to the type of wood to be processed and the desired chip quality. The most suitable chipper size is determined by the maximum trunk diameter to be processed and the desired production capacity. The desired chip length also inuences the performance of the chipper.

Thickness measuring systems THICK-SCAN behind the ContiRoll® optimizes the process and to reduces the costs while, at the same time, assuring the quality standard. If the gauges are located in the sanding line, the tool life of the sanding belts is enhanced and the quality is assured. The time is long past since panel thickness tolerances have been measured during production by handheld devices. Today, however, such measurement is carried out continuously online. In the majority of plants, quality control is not the rst priority for new investment for online thickness measurement. The current trend is to achieve the enormous potential savings in wood raw material, resin and energy consumption. If the upper tolerance level is exceeded, valuable resources are wasted. The Thickness Gauge prevents such losses. It is robust and reliable.
