摘要： A headbox for passing fiber suspension from a headbox entrance to a headbox outlet. A microturbulence insert with a plurality of flow channels inside the headbox. The channels are defined by channel forming elements having upstream ends. The headbox has an antechamber upstream of the turbulence insert. Respective individually adjustable additional feeds for feeding at least one second liquid into the antechamber upstream of the upstream ends of the channel forming elements of the turbulence insert. The feeds are preferably directed counter to the direction of the main flow of suspension into the channels of the turbulence insert. Vanes direct the main flow of suspension through the antechamber to the channels creating a respective sectioned flow to each channel. The additional liquid feeds are positioned to feed their additional liquid into the respective sectional flows after the main flow of suspension has already been diverted to a sectional flow. A method of use of such a headbox wherein each feed of additional liquid into the main flow of suspension is deflected in the direction of the nearest channel of the turbulence insert by the main flow of suspension and by the vanes which guide the main suspension flow toward the channels and which prevent the additional liquid feed from one sectional flow entering another sectional flow.
