Abstract

Fremgangsmåte og apparat (1) for fremstilling av et sammen- hengende sjikt fra hovedsakelig vannløselig, absorberende og hydrogeldannende polymermaterialer i partikkelform. Fremgangs- måten omfatter prosesstrinn som går ut på at tørre absor- berende geldannende partikler legges kontinuerlig i lag på en transportør. Partiklene blir så oversprøytet med en væske- blanding, som er en løsning av vann og fornetningsmiddel for polymerene i partikkelmaterialet. Den mengde som påsprøytes er tilstrekkelig til å frembringe effektiv overflatefornetning av partikkelmaterialet etter at sjiktet er herdet. Lagpåførings- og påsprøytningstrinn kan gjentas et antall ganger, hvis så ønskes. Trykk påføres så partikkelmaterialet ved å føre det gjennom et par pressvalser. Apparatet (1) omfatter en trans- portør (3) en eller flere materinnretninger (5) for lagpå- føring av de tørre absorberende geldannende partikler på transportøren, en eller flere sprøyteinnretninger (4) for oversprøyting av partiklene på transportøren med væskeblanding samt et par pressvalser (6).
