Menges Roller Co, Wauconda, Ill., USA, a designer and manufacturing of precision rollers for the paper converting industries, has announced the enhancement of its engineering department capabilities. Heat transfer rollers are a flagship product at Menges, and these engineering enhancements are primarily aimed at the heat transfer roll marketplace. Using advanced technology, Menges says that it engineers can now see and predict the exact temperature a roller will achieve and how that temperature will affect the web – all before the roller is built. These advancements help Menges Roller design rollers that perform specific tasks at very specific temperatures.
Using the latest computational fluid dynamics (CFD) technology, Menges Engineers compute all of the relevant factors—substrate types and dimensions, line speeds, thermal transfer fluid data, roller dimensions, flow rates, etc.—to see the temperature and thermal profile of a roller before it is built, the company emphasizes.
Matt Menges, president of Menges Roller, explained that "with modern converting applications, heat transfer rolls must perform at a very high level...and we take pride in building some of the best heat transfer rolls on the market. With these engineering enhancements, we're simply continuing on that path. Now, instead of just seeing static roller dimensions, we can demonstrate how changes to those dimensions affect the flowrate, the roller's temperature, the web's temperature, and the entire converting process. It's all about designing custom rollers that perform flawlessly in their application."
As part of these engineering department enhancements, Menges says that it also has invested in technology that allows engineers to model weight and load-bearing characteristics. This allows engineers to compare the strength and stress capacities of various steels in relation to roller design and component dimensions.
Menges Roller Co. serves the, paper, plastics, non-wovens, and steel markets with heat transfer and chill rolls, large process rolls, as well as web spreaders and other rubber-covered rollers. It also provides a full range of maintenance and repair services, from comprehensive roll refurbishing, to journal and core replacement, dynamic balancing, parabolic crowning, chrome finishing, and rubber covering options.
