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

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

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.

When resins containing isocyanate (MDI, PMDI) are used, particles and bres are prone to stick and cake to the steel belts in MDF, OSB and particleboard production. These processes require the use of release agents to be sprayed onto the steel belts. In the press infeed drum seat of the ContiRoll® one unit each is installed at the upper and the lower infeed drums. The release agent application device uses a dip roller to spread the release agent onto the press belts. The surface-textured dip roller rotates inside the release agent tub. The dip roller is pressed against the application roller (setting force is adjustable) to transfer the release agent. The applicator roll applies the agent to the steel belt. Features Precise and economical setting of the agent between 7 and 18 g/m²depending on the product.

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

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.

Wet electric lters are required where high demands are made on the levels of separation of aerosols, ne dusts and so on. Wet electric lters may be synergistically integrated into Siempelkamp's press extraction systems. Features Optimum performance through integration of the wet electric lters into the press extraction systems Water-circulation system for press extraction systems and wet electric lters Advantages Lower investment costs through integration High aerosol-separation levels (blue haze) High dust-separation levels Options Unscrubbed gas volume ows from 70000 Bm³/h to 150000 Bm³/h* *) Bm³ = cubic metre at operating pressure

HPC-40 is a roller rod chain with clearly dened characteristics developed with regard to modern mechatronic monitoring systems - created to enable reliable performance monitoring. Modern, computer-aided, reproducible manufacturing processes enable a more precise assembly of the individual components thus extending their service lives signicantly. Sensors monitor the wear thus contributing to an extended overall service life od HPC-40. For HPC-40, it was possible to extend the breaking load by 30 % and the fatigue strength by 40 %, as we were able to eliminate the risk of fatigue factors. Existing plants can, of course, be retrotted with the new HPC-40. HPC-40 helps fully utilise the features and functions of a modern ContiRoll® in a fast continuous operation

The cooling and stacking line, which is downstream of the ContiRoll, is the rst part of the nishing line. This is where the continuous process becomes a discontinuous one and the boards are cut from the endless mat. The cooling and stacking line is the rst section of an intralogistical concept that Siempelkamp develops with the customer: We work with the plant owner to dene the best master-board formats that will allow the later end-product formats to be made without ocuts. We develop all downstream processes for the master board and product on the basis of optimum material ows in constant dialogue with the customer. To this end, Siempelkamp sets up a team of experts that will act as the reliable partner throughout the process – from the intralogistical concept, technical implementation, assembly and commissioning/start-up to ongoing support.
