FELT MOISTURE

The water stored in the void volume of a press felt affects the sheet quality and the machine runnability in several ways:

  • an uneven felt moisture profile means an uneven sheet moisture profile
  • poor sheet dryness due to insufficient hydraulic pressure in the nip
  • sheet crushing or torn felts due to excessive hydraulic pressure
  • trim lifting, sheet stealing and edge drop-offs are often due to local moisture variations
  • press bouncing and other vibrations, for example barring
  • fines and fillers being flushed out of the sheet

Feltest products to measure press felt moisture profiles:

Feltest PresScan – the alternative, no-nonsense felt moisture meter.
Feltest Aequo – still under development, but this revolutionary new felt moisture profile meter will be introduced in a few months. Leave your email here if you want to be informed!
