Summary:PCT No. PCT/FR95/01028 Sec. 371 Date Apr. 5, 1996 Sec. 102(e) Date Apr. 5, 1996 PCT Filed Jul. 31, 1995 PCT Pub. No. WO96/05369 PCT Pub. Date Feb. 22, 1996Device for the formation of a fan jet (J) of liquid, of the type comprising: means (3) for supplying a liquid; means for distributing the delivery and for controlling the turbulence of the liquid supplied; outlet means (4) for the fan jet (J) formed, characterized in that the means for distributing the delivery and for controlling the turbulence of the liquid supplied are formed: from a first fixed curved conduit (15) for the flow of the liquid; from a second curved conduit (25) having an axis parallel to that of the first conduit (15); from means (26) for forming calibrated vortices having an axis parallel to the curved flow, so as to bring about a harmonic transverse distribution of the speeds and pressures and to control the scale and level of the vortices. Planned uses: headbox of a paper machine or installation for the couching of paper.
