Abstract

Keksinnön kohteena on menetelmä kuiturainan käsittelemiseksi, jossa menetelmässä kuituraina pintaliimataan pintaliimauslaitteessa (10), jossa pintaliima-aine (T) applikoidaan kuiturainalle kahden kovan pintaliimaustelan (11, 12) välityksellä pintaliimausnipissä (N). Kuituraina (W) pintaliimataan pintaliima-aineella (T), jolla on korkea kuiva-ainepitoisuus, epäsuoralla verhopintaliimauksella verhopintaliimauslaitteessa (10) ja pintaliimausnipissä (N) olennaisesti tasaisen painejakauman alaisena ja tasaisella nopeudella kuiturainan (W) poikkisuunnassa. Pintaliimauksen jälkeen kuituraina (W) lämpökäsitellään lämpökäsittelylaiteen (20) lämpökäsittelyvyöhykkeessä (Z). Keksinnön kohteena on myös käsittelyjärjestelmä kuiturainan käsittelemiseksi, joka järjestelmä käsittää pintaliimauslaitteen (10), joka käsittää kaksi kovaa pintaliimaustelaa (11,12), jotka muodostavat pintaliimausnipin (N). Järjestelmä edelleen käsittää lämpökäsittelylaitteen (20), joka käsittää lämpökäsittelyvyöhykkeen (Z). Pintaliimauslaite on verhopintaliimauslaite (10), jossa on epäsuora korkeassa kuiva-ainepitoisuudessa olevan pintaliima-aineen (T) applikointi ja toinen kovista pintaliimausteloista (11;12) taipumakompensoitu tela ja olennaisesti suora pintaliimausnippi (N) on muodostettu.
