Voith introduces eVenFilm Pro, a high-performance rubber film press roll cover. Engineered to meet growing demand from papermakers and board producers for ex-tended runtimes and lifespans even in the most extreme conditions, eVenFilm Pro is a high-end addition to Voith’s eVenFilm portfolio.
In paper and board production, sizing and coating is an essential finishing step. This is where the film press applies a thin, controlled and uniform starch coating to the sheet surface. The process direct-ly impacts final paper and board quality, surface properties, printability, strength and performance. Voith’s robust eVenFilm portfolio is designed specifically for the sizing and coating section of the paper production line.
Extended runtimes in extreme film press conditions
Developed in response to growing demand for highly durable film press roll covers, eVenFilm Pro is engineered to withstand higher line loads in the press nip, starch temperatures above 60°C and abrasive starch applications. eVenFilm Pro is also suitable for rolls that have no cooling systems during start up.
The roll cover for maximum protection against water permeation
In harsh environments, film press roll covers can weaken over time from a build-up of water permeation, resulting in unexpected cover failure. Severe water permeation leads to costly unplanned shut-downs and corrosion damage to the roll.
Building on the proven Voith roll cover technology and the eVenFilm range of covers, Voith experts have enhanced the polymer matrix design of eVenFilm roll covers to provide superior resistance to me-chanical wear and greater protection against water permeation. For added protection, an integrated safety module significantly reduces water permeation rates.
The new film press roll cover features an upgraded modular fiber and filler concept that can be individually tailored to the operating conditions, machine set-up and production goals. To ensure the most suitable roll cover is selected for each configuration and ap-plication, Voith experts work closely with papermakers.
Reliable, longer runtimes with eVenFilm Pro
With the launch of eVenFilm Pro, Voith further strengthens its film press roll cover portfolio for papermakers looking to increase runtime and runtime predictability even in extreme conditions.
