DIGITAL ANALYSIS IN THE PRESS SECTION: NIPMASTER INCREASES EFFICIENCY AND QUALITY
With NipMaster, Voith offers a powerful analysis tool that helps papermakers perform data- driven optimizations on the shoe press section of paper machines. The simulation-based evaluations specifically improve drainage, energy consumption and production performance – for greater efficiency, sustainability and quality in paper manufacturing. Efficiency, sustainability and production flexibility are among the key success factors in the paper industry. The basis for advancing these goals is a precise design of the press section. In this context, Voith's NipcoFlex shoe presses have been impressing customers for decades with their reliable performance and robust design. The main technological advantage of Voith's solution lies in the high press impulse, which is achieved through the interaction of a long dwell time in the nip and an optimized pressure gradient. Both parameters are crucial for maximum dewatering performance and consistently high paper quality. Optimal dewatering is the result of the precise interaction of a positionstable counter roll and a hydraulically pressed, concave pressure shoe – enclosed by a flexible press shell, such as the NipcoFlex sleeve from Voith. Holistic view of the press section However, the shoe press is only one part of the overall press section system. Experienced paper technologists know that the decisive factor is the complex interaction of all components. Only through careful coordination of the felt, shoe press belt, roll cover and doctoring can efficiency and productivity be significantly increased – and high paper quality guaranteed.
