    • Disclosed is a method for producing a fibrous web, in particular a paper web, paperboard web or tissue web, with which a material flow of higher consistency and a material flow of lower consistency are mixed in a variable ratio over the machine width and the mixed flow is fed via a headbox as a headbox stream to a mesh section, whereby the mixing ratio between these two material flows of different consistency in the respective mixed flow acts as the set-point variable for controlling the gsm substance of the fibrous web over the machine width. In this case the ratio between the fibrous material content and the filler material content in the material flow of lower consistency is established or controlled such that the filler material fraction in the fibrous web can be established or controlled at least essentially independently of the gsm substance.
    • 公开了一种用于生产纤维幅材的方法,特别是纸幅,纸板幅材或纸巾纸,其中较高稠度的材料流和较低稠度的材料流以机器宽度上的可变比率混合,混合 流动通过作为流浆箱流的流浆箱供给到网孔部分,由此,各个混合流中不同稠度的这两种材料流之间的混合比例用作用于控制纤维网上的gsm物质的设定点变量 机宽。 在这种情况下,建立或控制下部稠度的材料流中的纤维材料含量和填充材料含量之间的比例,使得可以至少基本上独立于gsm物质建立或控制纤维网中的填料部分。
