Abstract
Keksintö koskee menetelmää kerrostumien muodostumisen paperikoneen teloille kontrolloimiseksi, joka mainittu menetelmä käsittää anionisen tai ionittoman polymeerin vesiliuoksen levittämisen paperikoneen kuivapäässä paperin pinnalle tahmeiden aineiden ja/tai muun kerrostuvan aineksen, joka on peräisin paperista, estämiseksi likaamasta teloja.
