Abstract (en)
[origin: EP3617403A1] The invention relates to a method of treating a fiber web, in which method the fiber web is sized in a sizer (10), in which the sizing agent (T) is applied onto the fiber web by two hard sizing rolls (11,12) in a sizing nip (N). The fiber web (W) is sized with high solids content sizing agent (T) by indirect curtain sizing in a curtain sizer (10) and in the sizing nip (N) at substantially uniform pressure distribution and uniform speed in cross-direction of the fiber web (W). After the sizing the fiber web (W) is heat-treated in a heat-treatment zone (Z) of a heat-treatment device (20). The invention also relates to a treatment system for treatment of a fiber web, which system comprises a sizer (10) comprising sizing rolls (11,12) forming a sizing nip (N). The system further comprises a heat-treatment device (20) comprising a heat-treatment zone (Z). The sizer is a curtain sizer (10) with indirect application of sizing agent (T) in high solids content and one of which hard sizing rolls is a deflection compensated roll and a substantially straight sizing nip is formed.
