    • The invention relates to a process for the production of paper, card and board, including the steps of draining a filler-containing paper stock, having a certain fibrous concentration and containing at least one water-soluble amphoteric copolymer, with sheet formation in a wire section, then pressing the paper in a press section, diluting the paper stock to a fibrous concentration in the range from 5 to 15 g/l, draining the diluted paper stock to form a sheet, and then pressing the sheet in the press section to a solids content G(x) wt % or greater, such that G(x) computes according to: G(x)=48+(x−15)·0.4, where x is the numerical value of a filler content of the dry paper, card or board (in wt %), and G(x) is a numerical value of the minimal solids content (in wt %) to which the sheet is pressed.
    • 本发明涉及一种生产纸张,卡片和纸板的方法,包括以下步骤:排出具有一定纤维浓度并含有至少一种水溶性两性共聚物的含有填料的纸料, 然后在压榨部中按压纸张,将纸料稀释至5至15g / l范围内的纤维浓度,排出稀释的纸料以形成片材,然后将压片部分中的片材按压至 固体含量G(x)wt%以上,使得G(x)根据G(x)= 48 +(x-15)·0.4计算,其中x是干燥的填料含量的数值 纸张,卡片或纸板(以重量%计),G(x)是片材被压制的最小固体含量(以重量%计)的数值。
