Abstract

Seulalevy (5, 16) pulpperiin (2, 12) kuitumassasuspension valmistamiseksi. Seulalevy käsittää seulalevyn läpi ulottuvilla seula-aukoilla (7, 7a, 7b, 18a, 18b) varustetun seulapinnan (6, 17). Seulalevyn seulapinta käsittää ainakin kaksi seulapinta-aluetta (6a, 6b, 17a, 17b) ja ainakin yhdellä seulapinta-alueella olevan ainakin yhden seula-aukon (7a, 7b, 18a, 18b) koko on erilainen ainakin yhdellä toisella seulapinta-alueella olevan ainakin yhden seula-aukon (7a, 7b, 18a, 18b) koosta. Lisäksi pulpperi (2, 12), prosessi (1) ja menetelmä kuitumassasuspension valmistamiseksi.
