Best dewatering in class with proven shoe press technology
Since its first installation in 1984, the NipcoFlex module from Voith has proven itself in more than 620 shoe press installations. The decisive technological advantage of the shoe press is its high press impulse to the paper web. The combination of a long dwell time of the paper in the nip and optimal pressure gradients enables maximum production capacity at the highest quality level. Furthermore, NipcoFlex ensures that specific energy and production costs are minimized.

Key components
NipcoFlex module
The design of the NipcoFlex shoe with top and bottom parts in combination with an insulation leads to low bending, excellent line load profiles and reduced maintenance effort. The hydrodynamic shoe design provides a gentle pressure buildup and high safety against crushing. Additionally, the NipcoFlex features a single pressure control system for simple load control.
Voith’s patented tilted press stack design offers maximum drainage performance with the lowest rewetting of felts on the market. The NipcoFlex module ensures efficient sleeve water removal due to the internal loadable support bar with dampening effect. The intelligent internal air/vacuum control assures high sleeve lifetime and best energy savings.

HydroSeal seal strip for all suction rolls
Thanks to HydroSeal, the lubricating water is distributed continuously over the entire width of the seal strip, which allows the surface to be continuously covered with a homogeneous film of lubricating water. The efficient feed substantially reduces the amount of lubricating water required. Moreover, this new design prevents remoistening of the paper web and also improves the CD moisture profile.

Engineered for success
NipcoFlex increases production of board machine by 15 percent
The installation of a NipcoFlex shoe press was the first step in a comprehensive rebuild of the BM 1 at Macedonian Paper Mills (MEL) in Thessaloniki, Greece. This measure allowed the internationally operating manufacturer of board and packaging papers to increase machine production by 15 percent.
“With the new press section, we were able to improve board quality characteristics, reduce breaks and therefore significantly increase machine availability,” explains Georgios Georgiadis, the manager of the board factory.
Wanlida increases its production speed with NipcoFlex
In the shoe press upgrade on Wanlida Paper-Products Co., Ltd's BM 4 and BM 5 machines, the entire process from shutting down to restarting was carried out smoothly. The operating speed of the two machines went up by 50 to 80 m/min and the dryness of the paper out of the press section went up from 45% to over 50%, well surpassing the expectations of this Chinese customer.
