voith logo 2013Voith filed a patent infringement suit in Italy before the First Instance Court in Rome against Toscotec S.p.A. In its complaint, Voith alleges that a Tissue Machine with shoe press technology type Ahead 2.0S. version Shoepress produced by Toscotec S.p.A. in Italy and delivered to a paper mill in Portugal infringes Voith’s European Patent No EP 0 926 296 in Italy. The Voith Patent EP´296 protects Voith´s shoe press technology NipcoFlex TTM in combination with suction turning roll for Tissue machines.

Toscotec reacted to Voith´s infringement law suit by requesting the nullification of the Voith EP´296 patent as well as filing a request for ascertainment of non-infringement. In this respect it has to be noted that the validity of Voith´s EP´296 patent has already been unsuccessfully challenged before the European Patent Office in a previous opposition filed by another competitor.

voith logo 2013Voith has successfully completed the modernization of the paper machine PM 6 at BillerudKorsnäs AB in Gruvön, Sweden. As part of the rebuild project, the press section and parts of the dryer section have been modernized. BillerudKorsnäs manufactures on the PM 6 fluting for packaging paper from virgin fibers.

In the press section the existing roll press was taken out of the second position and installed in the first press position. Now a new NipcoFlex shoe press is being used as the second press. The NipcoFlex package delivered to BillerudKorsnäs is the first one which can achieve lineloads of up to 1,700 kN/m. This is only possible through an optimal combination of roll, shoe, press sleeve and press felt, which were all developed by Voith. Through the extremely high press pulse maximum dewatering is achieved with the highest paper quality. The closed web run through the press reduces sheet breaks and increases the runnability of the paper machine. Dryness and speed of the paper machine are increased simultaneously. In addition, the cantilevering structure in the shoe press position of the new press allows the use of endless felts.

For the conditioning of the press felt a ProLub cleaning system has been installed for the first time in a paper machine for packaging papers. ProLub cleans continuously the felt across the entire working width. The dryer section has been reduced by two dryers, resulting in further energy savings.

Also part of the scope of supply were MultiFlex machine clothings in the press and dryer section and an OnQ ModuleSteam steam box that ensures a uniform CD moisture profile and a higher dryness.

BillerudKorsnäs AB, headquartered in Solna, Sweden, emerged in 2012 from the merger of Billerud and Korsnäs and is one of the leading manufacturers of packaging paper made from virgin fibers.

voith logo 2013The new PM 5 for light-weight packaging paper at Modern Karton went into operation on time in Corlu, Turkey, in the middle of 2015. The entire process technology – from the stock preparation to the winder, including automation – was delivered by Voith and is characterized by low fresh water and energy consumption.

Decisive for the choice of supplier were Voith's references in the field of light-weight packaging paper and good experience in working with Voith. Ahmet Eren, managing director of Modern Karton, confirmed: "The comprehensive technological experience of Voith and the sustainability concept of the system convinced us. With this project we can build on our position in the market."

PM 5 is designed for a production speed of 1,500 m/min and has a wire width of 8,180 mm. It produces around 400,000 metric tons of packaging paper annually with a basis weight of 70 to 160 g/m². "We offer paper manufacturers in this growing market segment convincing, attractive solutions. Our system concept is perfectly adapted to the requirements of this market and our customers benefit from resource- and cost-effective, high-quality machines," said Andreas Endters, member of the Voith Paper Board of Management.

The modern stock preparation system comprises two lines and is specially designed for the high percentage of rejects in Turkish waste paper. Also the consumption of resources of the paper machine is as low as currently possible thanks to the technology supplied by Voith. For example, due to the installation of the innovative FlowJec dosing system in the approach flow system of PM 5, it is possible to exactly coordinate the use of chemicals. In addition, the OnV EnergyProfiler software localizes and visualizes all the energy consumption during paper production. Added to this are the automation, rolls and first clothing for the machine as well as all additional services and auxiliary packages. Voith has conducted extensive training for new staff and provides additional technology support. Modern Karton itself has set up a power plant on the mill premises to utilize the residual materials from the production process and to generate energy.

The Turkish company Modern Karton is part of the Eren group and is one of the largest manufacturers of board and packaging paper in Europe. At its Corlu location, 120 km west of Istanbul, 630,000 tons of packaging paper were produced annually on two machines prior to the startup of PM 5, both for the domestic market as well as for the export market. With the new machine the production will reach 1.2 Mio tons, which represents approx. 50% of Turkey’s total production capacity. Modern Karton has now further expanded its leading position in the market of packaging paper producers in Turkey.

Steel cylinders for the dryer section

EvoDry a winner at WEIG-Karton

2015 07 09 091141

Compared with cast iron cylinders, steel cylinders offer impressive features like higher thermal conductivity and greater material strength. These and other benefits mean that it makes good sense to install steel cylinders when upgrading dryer sections. Recently, WEIG-Karton also opted to install EvoDry steel cylinders at its plant in Mayen, Germany.

2015 07 09 091230Because EvoDry steel cylinders for the dryer section have high material strength they can have a thinner wall thickness than comparable cast iron cylinders. The temperature distribution in EvoDry drying cylinders is very even, which ensures optimum paper quality. The head and shell of EvoDry cylinders are welded to one another, so that larger sheet widths can be passed over the drying cylinder. The high material strength and low wall thickness of the steel cylinder result in higher thermal conductivity, improving heat transfer by 7 – 10 %. Thanks to this high efficiency, production can be stepped up or investment cost minimized when using EvoDry, as fewer drying cylinders need to be installed.

On two machines in Mayen, WEIG-Karton produces recycling board for the folding boxboard industry and plasterboard for the plasterboard industry. Total annual production is 630,000 metric tons of board. In 2014 the company decided to rebuild the dryer section of its BM 6 plasterboard machine. Voith won the order to convert the dryer section and installed a total of 31 EvoDry steel cylinders. The board manufacturer opted in favor of steel cylinders to achieve the maximum possible drying efficiency. As well as supplying the cylinders, Voith was also responsible for assembly and commissioning.

The rebuild of the dryer section was a smooth and fast process. After just 19 days, WEIG-Karton could resume production of plasterboard on its BM 6. “We are absolutely delighted that the rebuild was accomplished so quickly and smoothly,” says Henning Dippel, Operations Manager BM 6, adding: “We are equally pleased about our decision to install the EvoDry steel cylinders. We have been able to save space and yet achieve better runability and energy efficiency than before.” Shortly after startup of the EvoDry steel cylinders the guaranteed CD moisture profile values have already been achieved.

EvoDry drying cylinders can be used for the production of all paper grades. Optimum results are achieved with paper grades that are dried at high temperature, for example board and packaging papers.

TheWall is a new disperser filling from Voith that was developed to ensure an improved fiber treatment during a long service life. The design of TheWall is innovative and unique. It is made of an especially strong material and used by tissue, newsprint and magazine paper manufacturers as well as board and packaging paper producers. It can be integrated into all current Voith dispersers and in selected dispersers of other manufacturers.

VP TheWall 14

TheWall features three impressive innovations. Firstly, on the inner circle, the rotor vanes of TheWall ensure that the stock can be feeded uniformly to the distributing teeth. The new design also has a continuous functional barrier between the individual working edges of the filling. This prevents the stock from passing by untreated (short circuit flow) and gives the fine rows of teeth more stability. Another new feature is that the operating gap is adjustable in a wide range without impairing the efficiency of the disperser. Thus the energy input can be kept constant over the entire service life of the filling. At the same time, TheWall uses less energy than conventional disperser fillings while offering the same technological results.

Around 25 test installations are now successfully operating in various paper mills, with several customers ordering TheWall even before completion of the test phase. They will use them as their standard equipment.

Voith has brought to market a new screen element for the screw press. SplitScreen is the first screen element consisting of a supporting structure and a screen plate, enabling maintenance and inspection time to be significantly reduced compared with conventional cylindrical screen baskets. In addition, investment costs over the lifetime of the screw press are much lower than for conventional screen elements.

SplitScreen comprises a split supporting body with two removable screen plates instead of one cylindrical basket. This design enables direct access to the individual screw press components without having to dismantle it completely. Whereas with previous technologies the entire press screw including screen baskets had to be lifted out using an indoor crane to get to the cylindrical screen elements, SplitScreen allows the top half of the SplitScreen to be disconnected after lifting the hood to check the condition of the plate. If the screen plate, which is a wearing part, does actually need to be replaced the lower half can also simply be turned to the top. This then gives easy access to exchange the upper and lower screen plates. At the same time this makes the press screw accessible for inspection.

VP SplitScreen 14

With SplitScreen, the time necessary for replacing a screen element is only three to four hours instead of the average 24 to 48 hours that were previously needed. Moreover, procurement costs can be cut up to 40 percent per year after first installation, as in the event of wear only the screen plate and not the entire SplitScreen has to be changed. The large, open design of the screen area also helps improve the dewatering efficiency of the screw press.

SplitScreen is a standard feature of Voith's new InfiltraScrewpress. All conventional screen elements of Voith’s Thune screw press as well as screw presses from other manufacturers can be converted to SplitScreen.

The new screen element has already been successfully installed more than a dozen times worldwide and has also been retrofitted to conventional screw presses six times to date. The product is proving effective in the field and customers that have installed SplitScreen are very satisfied with its performance.
