A headbox ( 10 ) of a paper machine or such includes a bypass manifold (J<SUB>1</SUB>), from which the pulp is conducted by way of pipes ( 11 a<SUB>1.1</SUB> , 11 a<SUB>1.2 </SUB> . . . 11 a<SUB>2.1</SUB> , 11 a<SUB>2.2 </SUB>. . . ) of pipe rows in a set of pipes ( 11 ) and an intermediate chamber (E) into a turbulence generator ( 12 ), or from the bypass manifold (J<SUB>1</SUB>) directly into the turbulence generator and by way of the pipes ( 12 a<SUB>1.1</SUB> , 12 a<SUB>1.2</SUB> , . . . ; 12 a<SUB>2.1</SUB> , 12 a<SUB>2.2 </SUB>. . . ) of the turbulence generator's ( 12 ) pipe rows into a lip cone (K) and further out from the headbox on to a formation wire. The turbulence generator ( 12 ) of the headbox includes a fluidization element ( 14 ), wherein fluidization is carried out in one stage only and in which structure as little disturbance as possible is then caused to the fluidised flow.
