Method and apparatus for producing a fibrous web

A method for producing a fibrous web, with which a material flow of higher consistency and a material flow of lower consistency are divided among respectively shared sections over the machine width and the material flows of each section then mixed in a variable ratio to each other and the respective mixed flow 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 transverse profile of the gsm (grams per square meter) of the fibrous web, wherein the ratio between a fibrous material content and a filler material content in the material flow of lower consistency is at least one of controllably established and controlled prior to its division by at least one of adding and removing one of fibrous material and filler material from the material flow of lower consistency such that the filler material fraction in the fibrous web can be established or controlled at least essentially independently of the gsm.
