Stora Enso Narew in Ostroleka, Poland, has successfully started up its new Voith (Germany) supplied PM 5. Along with installation and startup, various services such as mill consulting and total roll management were part of the delivery.
The DuoFormer Base II installed provides for very good sheet formation, Voith notes, adding that thanks to its proven multilayer technology, the gap former ensures excellent CD basis weight profiles for packaging paper. A highlight of PM 5 is the DuoDry CC installed for the first time. What is special here is that this drying concept effectively reduces curl. The basic idea is a vertically inverted single-tier dryer group that functions as the last group. Substantial thermal energy is saved thanks to this setup.
The VariFlex winder is also part of the delivery. Equipped with an automatic splice system, it was able to process the paper machine's jumbo reel spools at a maximum operating speed of 2,800 m/min in a test run without any problem. The whole capacity of the paper machine can be handled in a safe and effective manner with only one VariFlex winder.
For Stora Enso Narew, it was important to build up a competent team at the location that can operate as independently as possible in the areas of production and maintenance. Through its Mill Consulting Service package, Voith can provide support at this point and continuously train the local team. Stora Enso Narew thus ensures itself a year of quick and direct access to Voith's knowledge and network of experts.
With a wire width of 8,600 mm, PM 5 produces around 455,000 metric tons of testliner and fluting annually in a basis weight range of 65-140 gsm. Its operating speed is 1,600 m/min. The location was taken over by Stora Enso a few years ago and is mainly used for supplying paper to its own group for the production of corrugated board paper.
