Voith has developed a new generation of sensors with regards to availability, reliability and maintenance handling. As the main components of the Quality Measurement System, the sensors measure the most important quality parameters of the paper being produced, such as basis weight, moisture, caliper and ash. The Quality Control System reduces as much as possible the variability in machine direction (MD) and cross direction (CD). This allows paper manufacturers to move quality targets in the most profitable operational zones – for example to maximize the moisture content of the paper.

  • Higher product quality due to modular and fully independent sensors with optimized housings and integrated temperature stabilization
  • Increased reliability and availability of the MD-Controls
  • Delivering more power within smaller and lighter sensors that require less machine space
  • Minimized maintenance effort through new plug & play standards

Higher product quality due to modular and fully independent sensors with optimized housings and integrated temperature stabilization
The sensors and components are designed to operate in challenging environments under harsh conditions of the paper mill. Special, high-temperature housing options are no longer needed. The new temperature-stabilized housings are designed for ambient temperatures up to 100° C / 212° F.

The new sensor generation features a compact, lightweight design and increases the reliability and availability of the machine direction controls.The new sensor generation features a compact, lightweight design and increases the reliability and availability of the machine direction controls.

Increased reliability and availability of the machine direction controls
A distinctive feature of Voith’s control concept are the machine direction controls based on physical models of the paper machine. Voith’s supervisory controls replicate the physical behavior of the process. The controls manage even high-frequent process disturbances. They also effectively reduce the time for grade changes and therefore minimize production losses.

Delivering more power within smaller and lighter sensors
The new sensor slots have been optimized in their width from 13 cm to 7.5 cm, which leads to smaller and lighter sensor packages, allowing more sensors to be installed in the available machine space.

Minimized maintenance effort with new plug & play principle
The heart of the new sensors is a processor board that provides precise and fast signal and data processing. Sensor features are easy expandable via firmware upgrades. Configurations and calibration parameters are stored inside the sensor and can be changed remotely. Furthermore, the new plug & play functionality reduces complexity in maintenance.

Voith is adding three new products to its range of Measurement and Diagnostic Services. MobiLab is a mobile analysis laboratory to investigate and optimize stock quality on site. With the SpeedUp Certificate, Voith is examining the possibilities for paper manufacturers to operate their paper machines above the original design speed, in consideration of the machine-dynamic behavior. And 3D Scan produces high-precision digital images of the current condition of the production facilities.

As part of its Servolution range, Voith’s Measurement and Diagnostic Services are tailored specifically to the requirements of the paper industry. Plant operators benefit from the mechanical and technological expertise of a full-line supplier and service experts with more than 10 years industry experience on average. This means that Voith’s Measurement and Diagnostic Services not only ensure smooth operation but also improve the economic efficiency of the system.

“Through our Measurement and Diagnostic Services, we are offering paper manufacturers tailored solutions that are state-of-the-art,” explains Stefan Natterer, Head of Measurement and Diagnostic Service at Voith. “And we are continually adding new technologies and services like MobiLab, SpeedUp Certificate and 3D Scan to our range.”

Through its Measurement and Diagnostic Services, Voith offers customized solutions for optimizing paper production.Through its Measurement and Diagnostic Services, Voith offers customized solutions for optimizing paper production.

MobiLab – mobile laboratory to optimize stock preparation
In the event of quality and process fluctuations in the paper production process, plant operators face the challenge of identifying the triggers. Generally, this has to be determined by analyzing and evaluating a large number of stock samples. However, as only very few paper manufacturers maintain a well-equipped wet laboratory on site, large numbers of samples must be sent to designated institutes for testing. This not only involves a significant logistical effort but is generally also very time-consuming and costly. Due to the complex process necessary to preserve the samples, valuable results may be falsified or even rendered worthless.

The solution: the Voith MobiLab – a fully equipped mobile containerized wet laboratory for the analysis of typical problems in the stock preparation process, from fiber loss to issues with chemicals mixing. When trying to identify the causes, Voith experts on site can utilize all the usual analysis processes.

In addition to laboratory measurements in the MobiLab, Voith also offers the Wet End Process Analysis Package. Thanks to a combination of various measurement techniques (pressure pulsation, stock density, air content, online paper transmission and offline Tapio analysis) the basis weight stability profiles of the paper can be determined, for example. Using a paper sample database and best practices, the current status and any faults can be identified quickly and efficiently and action initiated to rectify them. In addition, the MobiLab can be used when trialing new paper grades or qualities in the course of machine tests on actual customer equipment – to get the best possible results from what are generally expensive field tests.

SpeedUp Certificate – verifying speed increase options
In theory, the operating speed of a paper machine can be increased by installing a new, technologically improved component, and as a result the cost efficiency of the entire manufacturing process improved. But what if the original maximum design speed of the paper machine is lower than the potential speed of the new component?

With the Voith SpeedUp Certificate, companies can have an audit performed on the entire paper machine to determine whether the design of the machine components is suitable for a future operating speed that is higher than the original design speed. For example, machine dynamic limitations such as vibrations, critical speeds, drive design, condition of existing components and technological process considerations are checked as necessary. Unsuitable components are identified, and the measures required to increase the operating speed are indicated. Such measures could include, for example, the replacement of unsuitable guide rolls or adding bracing to the machine frame.

Following successful completion of a speed-up inspection by Voith, the machine gets a “Type Design Speed Certificate” that defines a new maximum design speed of the analyzed components and machine groups. This gives paper manufacturers a reliable basis to work with before they increase the production speed of their machine.

3D Scan – spatial image of actual machine accurate to the millimeter
Paper mills change over time, for example as a result of upgrades and the installation of new components. Often, however, this is not documented in the design drawings, which can cause complications in the event of further rebuilds.

With the 3D Scan, the Voith experts on site can create a digital spatial image of a machine and its environment, and in this way record the actual situation of the machine to an accuracy of one millimeter at a scanning distance of ten meters and a maximum scanning range of 360 meters. The real data obtained can be stored as point clouds in various formats and then processed to be used as a template for a rebuild project, installation check or for measurements on your desktop. Point cloud data can be combined with CAD data to produce a machine model including all cable and piping. The spatial review in the 3D CAD system with automatic collision check reduces the likelihood of complicated rework and adaptations on site.

Attila Bencs, General Manager at Hamburger Hungaria Ltd., views this as a distinct advantage: “When converting the pulpers at our plant in Dunaújváros, the 3D Scans had already given us the most accurate information in advance on the spatial conditions on site. The improved visualization was beneficial to both all project participants and machine operators,” Bencs says, summing up the extremely useful deployment of the 3D Scan by Voith, and adding: “This saved us a lot of time and work for the rebuild.”

Ten years ago Papierfabrik Palm put the PM 7 supplied by Voith into service at its King’s Lynn facility in the UK. Voith has now been engaged to supply new calender rolls with heating system for the newsprint paper machine. The rolls are scheduled for completion by the end of the year.

  • Rolls cast at Hüttenwerke Königsbronn foundry
  • High-quality newsprint and excellent printing results
  • Improved paper quality and expanded product portfolio

Rolls cast at the Hüttenwerke Königsbronn foundry
The scope of the order consists of identical calender rolls and a new heating system. The calender rolls are being cast at Hüttenwerke Königsbronn in the Heidenheim district, a foundry that can look back on a 650-year history.
The casting for the roll tube has an outer diameter of around 1.6 meters, is about 11 meters long and weighs approximately 76 metric tons. The material used is ductile cast iron, which allows the finished calender rolls to be heated up to a surface temperature of 210°C. “These dimensions make them the heaviest calender rolls worldwide made from the modern material CDI”, says Christian Tenbruck, Vice President Sales & Application at Voith. The rolls also undergo an induction-hardening process during fabrication. Higher load capacity, fatigue strength and durability are just some of the benefits of this hardening process.

Papierfabrik August Koehler SE has engaged Voith to comprehensively modernize the PM 5 paper machine at its main paper mill in Oberkirch. This vote of confidence in Voith is further evidence of the long-standing successful business relationship between the two companies.

  • SpeedSizer AT improves competitiveness and increases flexibility
  • Fewer downtimes and web breaks 
  • Contactless high-performance qDryPro Compact dryer increases efficiency
  • Upgrade to pave the way for future speed increase and second expansion phase

Voith worked with Koehler to develop a customized concept for the PM 5 that improves competitiveness and increases flexibility. Downtimes and web breaks will be reduced and efficiency increased. The upgrade with high-tech components will allow paper coated on both sides to be produced in a larger operating window in future. The paper machine is also being prepared for a speed increase in a possible second expansion phase.

To achieve these ambitious project goals and improve the customer’s competitiveness, Voith’s upgrade incorporates the applicator unit SpeedSizer AT, which is ideal for fast running paper machines, the energy efficient, contactless high-performance dryer qDryPro Compact, and the PrevoSystem for short and reliable threading. For the pulpers in the press and reeling section, new pulping units are to be installed for even more effective pulping of the broke.

Voith PM 5 August Koehler SE Oberkirch, Germany.Voith PM 5 August Koehler SE Oberkirch, Germany.

“The main reasons for upgrading our PM 5 are to increase efficiency, improve flexibility to allow a wider range of paper grades, and reduce costs.”, says Hartmut Felsch, Mill and Division Director Oberkirch at August Koehler SE.

SpeedSizer AT: Optimum film application at all times
SpeedSizer AT enables uniform, flawless application of sizing and coating films and improves paper qualities, penetration and surface coverage. The carbon fiber support beam is dimensionally stable regardless of external temperature fluctuations. It maintains maximum straightness and allows uniform film application over the entire operating period. The doctor rod holder used will be the patented modular system SpeedRod M, in which doctor rod, doctor bed, pressure hose and clamp hose are integrated in one component. Any type and diameter of doctor rod can be selected without necessitating laborious machine adjustments. Because individual components can be replaced, malfunctions can be fixed quickly and easily, downtimes reduced and production losses minimized. The SpeedSizer AT has already proven effective in more than 300 customer installations.

qDryPro Compact: Energy efficient, contactless high-performance drying
The qDryPro Compact is a high-performance dryer for paper and board grades with single or double-sided coating. There is usually very little space available for paper machine upgrades. This is why the air system of the qDryPro Compact was designed to be especially space-saving. The air circulation fan is integrated into the dryer. The combination of infrared and hot air drying is extremely energy efficient, because it uses only the waste heat from the infrared heaters to heat the air hood.

PrevoSystem: Reliable and short threading processes
Voith’s scope of supply also features the Prevo threading and cutting system including the PrevoThread C vacuum threading belt and a PrevoCut DTC double tail cutter. Because an inefficient threading process can stop production for up to an hour for every web break and restart, Voith developed the fully automated PrevoSystem, which ensures reliable threading processes and short threading times. It reduces production losses after every web break and increases productivity. 1,000 Prevo solutions installed worldwide testify to its benefits.

About the Koehler Paper Group
With a history that goes back some 210 years and a turnover of around EUR 900 million, the Koehler Paper Group is one of the few independent family-owned German companies in the paper industry.

At its headquarters in Oberkirch and paper mills in Kehl, Greiz and Weisenbach, its workforce of 1,850 people uses cutting-edge technology to produce more than 500,000 metric tons a year of specialty papers and board for the worldwide market.

SealView technology captures the development of wear on every single seal strip and can be used with conventional and Voith HydroSeal seal strip designs. Its functional principle is based on a non-electric solution, which ensures maximum reliability in the adverse suction roll environment.

Digital wear detection for seal strips
Seal strips in suction rolls delimit the individual vacuum zones and are subjected to constant wear as they are pressed against the rotating suction roll shell. At the moment, it is not possible to determine the current state of wear after its final assembly or while the roll is in operation. The right time for a roll change has therefore generally been determined based on empirical values. When operating parameters change, for example due to a failure of individual lubrication nozzles, an unexpected vacuum failure might occur which negatively influences the planned runtime of the roll.

With SealView, this risk is now a thing of the past. The new technology can be built into the suction roll – independently of roll design and brand – during a roll service at one of Voith’s service centers. After changing the rolls, Voith personnel will do the initial commissioning and training at the paper machine.

Non-electric wear detection for seal strips on suction rolls with SealView technologyNon-electric wear detection for seal strips on suction rolls with SealView technology

No unscheduled machine downtimes and sufficient time to plan replacement part procurement
The system alerts the operator when the seal strip has reached half of its service life. When it gets to a safety margin before the maximum wear level, an alarm is triggered. Via a visual representation on a monitor, the system informs the operator about the actual wear condition and the probable remaining service life of the seal strip, alerting the operator in good time to the necessity for a roll change. Moreover, the associated notifications are sent by email and are therefore available to personnel on their smartphones.

After receiving this information, the operator has sufficient time to systematically plan the disassembly of the roll and coordinate further action for a roll service and the procurement of replacement parts with the Voith service department. “A further advantage of the new SealView technology is that it is no longer necessary to keep an expensive set of seal strips inventory in the warehouse for emergencies. This helps customers to reduce working capital, a topic which plays a more and more important role in our industry,” explains Jochen Honold, Global Product Manager Mechanical Roll Service, Voith Paper.

Highest system reliability through seal strip wear tracking, even with extended run timesHighest system reliability through seal strip wear tracking, even with extended run times

Longer suction roll service life and maximum reliability
The system reveals its full potential, particularly in the case of runtime extensions over and beyond the usual lifetime. Because the seal strip wear is displayed, the operator can rely on the system over extended periods of use without worrying about an unscheduled downtime.

Voith has decades of experience in the maintenance of rolls in general and suction rolls in particular. Based on the information currently available, particularly important components need to actively communicate with the operating and maintenance system to achieve maximum reliability. Through its SealView technology, Voith has reached another milestone in implementing this approach in respect to Industry 4.0.

As part of an extensive investment program, the company plans to produce up to 600,000 tons of kraftliner per year at its new plant in Ust-Ilimsk, Eastern Siberia, starting in 2021. The key partner in this project is the technology group Voith, which is working with Ilim Group on this scale for the first time.

  • Production of up to 600,000 tons of kraftliner per year
  • Project scope includes two BlueLine refining lines, one XcelLine system, drive components, comprehensive training measures and the Process Line Package (PLP)
  • Integrated Papermaking 4.0 components increase efficiency, product quality and machine availability

As part of the Process Line Package (PLP), Voith assumes full responsibility for the project. The experts for the entire papermaking process ensure that the plant in Siberia starts up safely, on schedule and with precisely coordinated components. The PLP reduces the number of required interfaces and contact persons and simplifies the entire project handling, which ultimately also reduces costs.

As a full-line supplier, Voith is able to provide all system components including screens for each section, as well as comprehensive Papermaking 4.0 digitizing technologies. In addition, the globally positioned group is responsible for the electrical equipment and the entire drive system of the plant. A comprehensive training program on the new machine is also part of the project scope.

With XcelLine paper machines, Voith offers efficient paper production of every paper grade on a new level.With XcelLine paper machines, Voith offers efficient paper production of every paper grade on a new level.

“Voith is partnering with Ilim Group in this historical and outstanding project. It will become a milestone for the Russian pulp and paper industry, and we are proud to contribute with our deep experience and latest innovations,” says Christoph Müller-Mederer, President Projects EMEA at Voith Paper.

The centerpiece of PM 1 in Ust-Ilimsk is a XcelLine of the latest generation. With a wire width of 10,300 millimeters, the Ilim Group plans to produce up to 2,150 tons of kraftliner per day with basis weights between 80 and 175 grams per square meter. This will make the new machine the most powerful of its kind in the world. The production speed of 1,200 meters per minute also represents a top performance.

OnCare.Health and OnCare.Asset as well as OnEfficiency.Strength are among Voith’s Papermaking 4.0 digitalization technologies that ensure consistently high product quality and reliably efficient manufacturing. In Ust-Ilimsk, OnCare.Health monitors the current status of the system at all times, registers even the smallest malfunctions and their causes, alerts the papermaker and independently works out optimization measures. In combination with the intelligent maintenance management system OnCare.Asset, this enables a significant increase in machine availability.

In addition to the record-breaking XcelLine machine, two BlueLine stock preparation systems are also included – one for hardwood pulp, the other for softwood pulp. They ensure exact compliance with the composition of the pulp. Voith's technology thus sets the course for maximum product quality right from the start of the process.

The preassembled equipment will be erected directly at the construction site in Ust-Ilimsk. In addition to the XcelLine and the BlueLine, components supplied by Voith will include a FlowJec dosing system for additives, the former section with two Fourdrinier machines equipped with MasterJet Pro F, a ModuleJet II and DuoShake, EcoCal hard calender, the drying section with CombiDuoRun dryers and a Sirius reel with EcoChange and VariFlex Performance winder. The delivery of the 79-ton Nipco-P roll represents a particular challenge for the project.

“Ilim sees its leadership role not only as the largest pulp and paper product manufacturer, but also as an investor into state-of-the-art innovative technologies. This investment decision was based on impressive results demonstrated by Ilim Group in the Asian market”, said Xenia Sosnina, General Director of Ilim Group. “We know this market well and see its opportunities. The contract we have signed is one of the largest contracts in the history of the Russian pulp and paper industry. Voith Paper, a leading manufacturer of paper and board machines with the highest level of automation and digitalization, has become our partner under this project. Our project will be one of the most advanced high-tech projects in the global pulp and paper industry, and will provide the Asian market with the volumes of high quality products it demands.”
