AboutMWN Niefern Maschinenfabrik GmbH.
MWN has always specialized in producing state-of-the-art rolls, ever since its foundation in 1909. Today, we consider the engineering and production of suction rolls and suction roll shells one of our core competencies. MWN first used a multispindle drilling machine to produce suction roll shells as early as the 1950s. By the 1990s, we increased our production capacity by adding computerized gun-drilling machines and new machine tool facilities. MWN still enjoys coming up with innovations today as much as it has in the past. In 2010, MWN set up a new production building covering 2000 square meters.
This expanded the overall production area to 7600 sq m. MWN’s modern lifting system is no less than 25 meters wide with a maximum load of 80 tons, allowing us to produce and service larger rolls than ever before. MWN also has the very latest in innovative test stand equipment to ensure everything they supply to customers meets the very highest standards. MWN regularly test rolls weighing up to 80 tons, putting them through their paces with up to 2000 revolutions per minute. For you, this means total reliability in production. MWN also places emphasis on world-class service and support. What matters most is delivering precisely the solution you need.
So as well as offering advice from highly qualified specialists, they use state-of-theart materials and provide no-worry, full-service support – at your mill or in the MWN factory. MWN is an international company doing business wherever paper is manufactured, with the customer base to match. These customers are a testament to our stringent technical standards and the quality of all MWN products. MWN’s clients in North and South America are serviced by their own separate sales office. MWN is one of the world’s leading specialists in the design and production of suction rolls and functional rolls. With over 100 years of history and engineering experience, MWN is an expert partner to the paper, cardboard, tissue and foil industry.
To manufacture, process or treat paper webs, films or non-wovens, MWN products have to address some highly exacting demands. With machine speeds of up to 2500 m/min and widths of up to 12 m, everything needs to work in total harmony. And MWN provides what its customers need - in every respect. Probably the most important factors for our clients are the reliability and longevity of our products, as round-the-clock production means rolls must stay up and running.
A particular specialty: Custom-made suction rolls and suction roll shells, suitable for a variety of applications. The rolls offered by MWN can be used individually and offer tremendous dewatering performance on all kinds of paper machines – ideal for raising the dry content of paper sheets and improving material strength.
Focusing on precision: suction rolls and suction roll shells.
