Voith Revolution Felt Boosts Press Performance

Voith, Germany, has launched its newly-developed Revolution press felt for board and packaging paper machines. Along with increased drying performance, Voith notes that Revolution ensures shorter startup phases, energy savings, and consistent quality characteristics over its entire service life.


The key innovation of Revolution is its structure, which has a special polymer layer, according to Voith. The felt can thus control the flow of water before, during, and after passage through the nip. This allows it to dewater better and contaminate less. The dry content is higher by up to 2% than with a conventional felt. The self-cleaning effect also helps to ensure that felt performance remains the same over its entire service life.


Voith further points out that paper produced with the aid of Revolution has especially good surface characteristics due to the larger contact surface with the paper or board web, adding that practical testing confirmed that the new felt allows substantially shorter startup times. From the beginning, it says, the level of nip dewatering is very high. Revolution thus has a positive effect on energy balance.
