Almost every paper mill using forming fabrics has one: a mechanical tension gauge to measures the tension of Paper Machine Clothing, mostly forming fabrics. When these instruments are not in a perfect condition they can cause serious problems on the paper machine like torn fabrics, too narrow and/or too long fabrics and bearing failure.

Surprisingly, most papermakers choose the first option.
This whitepaper explains a dangerous production habit we need to break. It then offers a new approach to PMC trials that allows paper mills to better assess their machine clothing—and PMC suppliers to innovate.
Read MoreA board machine regularly has problems with unstable streaks. It comes up suddenly and is uncontrollable. It leads to unsaleable paper quality and many sheet breaks, hence much production loss. The streaks are fluctuations of high and low basis weight in machine direction and are completely parallel over the full sheet width.
This whitepaper describes how the cause of this problem was identified and solved with the help of a Feltest FiberScan.
Read MoreThis whitepaper will show you how you can increase machine output through better performing press felts. Simply because there is still a lot of potential in this part of the machine.
Read MoreIn order to remove water from the sheet in the press section, water must flow easily into the press felt. On the other hand, at the exit of the press nip, water must be kept from flowing back into the sheet. These conflicting demands ensure that felt permeability is always a compromise between good dewatering and re-wetting.
This whitepaper gives background information on felt permeability and describes hands-on tools to determine and optimize the permeability of felts which are running in the machine.
Read MoreWhen a forming fabric doesn’t want to run straight it usually causes many problems and costs. In the worst case it actually runs into the machine frame and the fabric is completely destroyed. But also continuous strong guiding corrections lead to excessive fabric wear and hence high costs. This article explains the principles of forming fabric guiding and gives the papermaker tips on how to systematically solve guiding problems.
