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.

The continuous non-contact Area-Weight Scale CONTI-SCALE X MULTIENERGY determines the panel weight and its distribution during production by measuring the area-weight and by taking the known panel dimensions into account. CONTI-SCALE X MULTIENERGY uses X-ray technology. Two X-ray tubes are located on a horizontal frame above the panel. The low energy X-ray beams are focused across the production width, but scan the full width of the panel. Metal plates on each side of the system prevent someone reaching inside the radiation area. There is no risk to human body parts which might stay beside/outside the system. The X-ray energy will be absorbed. Several detectors are lined up along the lower beam under the panel to measure (per track) the absorbed X-ray energy. This is how the area-weight is measured.

The ultra-thin board package consists of a special cylinder conguration with additional double-acting cylinders. Its concept enables the production of ultra-thin engineered boards in a reliable and stable process. A standard ContiRoll® has a degassing zone in its front section. Double-acting cylinders serve to lift the sides of the press gap to enable a controlled degassing. Since ultra-thin boards are produced at especially high speeds, this standard degassing zone is not long enough for the mat to degas. The optional ultra-thin board package includes additional dierential cylinders functioning as double-acting cylinders to extend the degassing zone signicantly. Dierential cylinders in the remaining part of the press ensure that the upper and the lower steel belts do not make contact during ultra-thin board production, even if there were no mat in-between. Features Additional dierential cylinders operating as double-acting cylinders

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

CMC TEXPAN oers several solutions for the removal of metal (ferrous and non-ferrous) contaminants, based on dierent principles of operation, hence suitable for various applications. magnetic drum The machine consists of a rotating drum made of stainless steel

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 particleboard forming line consists of machines for forming and monitoring the particle mat. Additional devices for quality monitoring complete the function of Siempelkamp’s forming line. The plant modules can be adjusted to the respective requirements thus preparing the mat optimally for its compaction in a ContiRoll®. The equipment is designed to produce board thicknesses between 6 and 40 mm without any problem. A typical particle mat former consists of one or two mechanical mat formers for the core layer and two wind sifters for the top and the rear surfaces. The three-layer particleboard thus produced distinguishes by a homogeneous, core layer consisting of coarse particles and two surface layers, the particle size of which is decreasing from the core to the outer faces.

The secondary heating system is an integral part of the ContiRoll® and one of the decisive factors for its optimal functioning. For a perfectly dimensioned secondary heating system signicantly contributes to its eciency. The oil is heated in the boiler house to the temperature required and delivered to the primary circuit. The secondary heating station maintains the temperature in the secondary circuit to the press at set temperature by mixing the oil returning from the press that has already cooled down with the hotter oil of the primary circuit. The thermal oil transfers its thermal energy via hot platens, roller rods, steel belts to the mat to be pressed. Features Advancing temperature of the primary circuit is 280 °C Quick-acting aps for immediate re protection Heating circuits for setting the temperature distribution required by the respective process over the entire press length
