The present invention relates to an improved paper machine wire pit of reduced volume and made of modules that may be located in several various relative positions, at the level of the mill or at the bottom of the mill, for separating gas from white waters, while maintaining laminar liquid flow. A characteristic feature of the wire pit (50) according to the invention is that its wall/walls (52', 52", 54', 62) converge downwards so that the average flow direction of the liquid along the most part of the wire pit (50) height deviates from vertical.
La présente invention se rapporte à une fosse sous toile. Une caractéristique particulière de cette fosse sous toile (50) est que sa (ses) paroi(s) (52', 52", 54', 62) converge(nt) vers le bas de sorte que la direction moyenne du flux de liquide le long de la majeure partie de la hauteur de cette fosse sous toile (50) s'écarte de la verticale.
