With +Pro, the combination of fiber mixture and binder system offers an exceptionally uniform felt surface, resulting in a smoother paper surface and, therefore, better printability of the material. A benefit of +Pro is the more uniform pressure distribution across the whole fabric. This enables for a higher dryness in paper production and, at the same time, mitigates the number of costly and time-consuming web breaks. The uniform pressure distribution also guarantees stable running conditions, mitigated wear on the press fabrics, and therefore a longer felt life. With these qualities, +Pro offers a basis for efficient papermaking production.
Besides +Pro, Voith has two other modular product extensions for press fabrics in the Efficiency Add-Ons family. +Peak has been on the market for several years. It is an elastomer material integrated into the fabric, which mitigates the startup time of the felt and ensures a lasting high level of performance. +Peak compresses more than a standard felt. This means the felt reaches functional saturation and, therefore, its full potential much faster. +Peak has increased the machine efficiency for several customers.
While +Pro and +Peak boost efficiency on all paper machines, +Up is an add-on optimization for tissue manufacturing requirements. The objective of the development launched in 2019 was to bring about the faster startup of the felt. The startup time has been reduced by up to 50 percent. The higher saturation potential during startup enables a more stable and rapidly available capacity, which means higher overall productivity throughout one felt cycle.
Efficiency Add-Ons such as +Peak and +Up have already paved the way for efficient and sustainable production on several paper machines worldwide. With +Pro, the company has added another innovative module to this range, further assisting the customers in enhancing their products' quality.
