The control maintains a stable flow in a section (11) of a multiple flow conveyor. It has at least one grill or roller to prevent irregularities occurring downstream. The grill is positioned in the flow, in front of or at the rear of the section w.r.t. which the disturbances arise upstream or downstream. - The grill(s) can have guide wings (19a-c) and may cooperate with rollers (16a,b,c). The grill can produce a multiple phase flow having a predetermined disposition. (4/5) EPAB- EP-140743 B A device designed to maintain roughly stable flow conditions in a part of a polyphasic flow, characterised in that it consists of two distrubance prevention devices (12 and 13) suitable for stopping disturbances in the flow originating upstream and/or downstream, the said devices (12 and 13) being disposed in the flow of the said part (11).
