1. Menetelmä kalvon valmistamiseksi fibrillisellusta, jossa menetelmässä -johdetaan fibrilliselludispersiota suodatinkerroksen päälle, - valutetaan fibrilliselludispersiosta nestettä alipaineen vaikutuksesta suodatinkerroksen läpi, joka on fibrillisellun fibrillejä läpäisemätön mutta nestettä läpäisevä, kalvoarkin muodostamiseksi suodatinkankaan päälle, - kohdistetaan kalvoarkkiin lämpöä kalvoarkin vastakkaisella puolella läm-pöpintakontaktin avulla samalla, kun jatketaan nesteen valuttamista suodatinkerroksen läpi suodatinkerroksen yli vaikuttavan paine-eron avulla, joko i) kalvoarkin pinnan kontaktissa lämpöpinnan kanssa tai ii) lämpöpinnan kontaktissa lämpöpinnan ja kalvoarkin väliin sijoitetun kerroksen, kuten suodatinkankaan kanssa tai rakennekerroksen kanssa, johon kalvo laminoidaan, jolloin myös lämpöpinta kohdistaa kalvoarkkiin painetta, joka saa aikaan ainakin osan suodatinkankaan yli vaikuttavasta paine-erosta, ja - irrotetaan kalvoarkki suodatinkerroksesta erillisenä fibrillisellukalvona, tai vaihtoehtoisesti - pidetään suodatinkerros kalvossa olennaisena osana kalvotuotetta, joka käsittää suodatinkerroksen ja fibrillisellukalvon.
2. Patenttivaatimuksen 1 mukainen menetelmä, jossa nestettä valutetaan kalvoarkista suodatinkankaan läpi alipaineen vaikutuksesta samalla, kun lämpöpinta kohdistaa kalvoarkkiin painetta, jolloin mainittu alipaine ja lämpö-pinnan kohdistama paine yhdessä saavat aikaan suodatinkankaan yli vaikuttavan paine-eron.
3. Patenttivaatimuksen 1 mukainen menetelmä, jossa nestettä valutetaan kalvoarkista suodatinkankaan läpi ainakin yhteen adsorboivaan arkkiin samalla, kun lämpöpinta kohdistaa kalvoarkkiin painetta, jolloin mainittu lämpöpinnan kohdistama paine saa aikaan suodatinkankaan yli vaikuttavan paine-eron.
