The papermaking machine contains at least one water pervious dewatering wire or the like for forming a fiber web, particularly one layer of a multi-ply fiber web, and at least one headbox for infeeding a fiber stock suspension to be applied in the form of a free jet to the dewatering wire. Between the headbox and a section of the dewatering wire extending along the headbox there is arranged at least one deflecting device for separating and withdrawing a partial flow or stream of the fiber stock suspension. The deflecting device can be inserted into a marginal region of the free stock jet. Such an arrangement enables, for example, a continuous or infinitely variable adjustment of the format width of the fiber web to be produced. During use of the deflecting device, the partial flow or stream of the stock is deflected prior to the formation of the fiber web and is kept away from the following operational or working sections of the papermaking machine, in particular from a second fiber web or ply located thereat. If desired, the deflected partial stock flow can be returned to the fiber stock suspension supply or infeed system preceding or upstream of the headbox for re-use of the unmixed fiber stock material.
