An apparatus for controlling the consistency of a flow of stock solution in a papermaking machine comprises a generator (10) of ultrasonic waves (12-14) and an ultrasound absorber (24) arranged in such a way that the flow of the stock solution flows for deviating the fiber particles (18-20) suspended within the stock solution are deviated from the flow direction for the control of the cross machine direction stock solution consistency profile.
La présente invention concerne un appareil destiné à contrôler la régularité d~un flux d~une solution mère dans une machine de fabrication de papier qui comprend un générateur (10) d~ondes ultrasonores (12 à 14) et un absorbeur d~ultrasons (24) disposé d~une manière telle que le flux de la solution mère s~écoule pour dévier les particules de fibre (18 à 20) en suspension dans la solution mère qui sont déviées à partir du sens d~écoulement pour le contrôle du profil de régularité de la solution mère en sens travers.
