摘要： A papermaking machine is shown with an inner traveling screen and an outer traveling screen which are led towards each other to form a generally layered arrangement therebetween during a region of their joint travel and, in such region, the inner and outer screens are caused to pass over a portion of a water extracting or dewatering roller; a water collection apparatus situated outside of the roller serves to collect water centrifuged from the screens passing over the roller; and a preliminary water extraction zone preceeds the roller and such zone extends over a portion of, for example, a generally horizontal section of the inner screen.
