ABSTRACT OF THE DISCLOSURE The flow ratio of a paper machine headbox is adjusted by arranging such a by-pass out from the slice chamber that the flow conditions, such as the speeds and turbulences in all parts of the headbox remain unchanged regardless of the adjustment. The adjustment is carried out by opening the slice chamber wall or by using a separate discharging device positioned inside the slice chamber.
