摘要： Headbox for a paper-making machine including a nozzle extending transversely to the machine running direction across the machine width. The nozzle has a lower and an upper continuous wall each extending across the machine width. The lower nozzle wall is supported by several separate supporting elements distributed across the machine width on a foundation. The supporting elements are non-rigid or flexible plates to permit bending in a direction transversely to the machine running direction. Alternatively or additionally, a swivelable or pivotable upper nozzle wall is connected by several separate supporting members distributed across the machine width to a transverse bar attached above a swivel axis. The supporting members are non-rigid or flexible plates to permit bending transversely to the machine running direction. Alternatively or additionally, an upper arm and a central part of a central component of the headbox are each segmented transversely to the machine running direction, while an inlet-side central part of the central component and the lower nozzle wall are each designed to be continuous transverse to the machine running direction.

摘要： Process for modifying an existing breast box for a paper or cartonmaking machine as well as an intermediate portion for carrying out the process. During the fabrication of a breast box for a paper or cartonmaking machine an intermediate portion is interposed between a supply apparatus and a downstream guiding device, with the material suspension flowing through this intermediate portion wherein, via supply lines, located on the intermediate portion, a liquid is added which differs from that of the suspension stream. Particularly, in this manner, already existing breast boxes can be converted, to water dilution technology, with this invention setting forth special embodiments of differing intermediate portions that can be utilized therefor.

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.
