摘要： This device, preferably formed as a dual paper machine, has according to a preferred embodiment two endless screens, mainly a lower screen (21) and an upper screen (22). The lower screen (21), on which is formed a paper web, and the upper screen (22) are moved together in the lower part of a dehydration cylinder (25) arranged in the upper screen. Both screens (21,22) are unrolled from the rising lower quadrant of said cylinder (25) and are laid on the upper part of the support cylinder (26) arranged in the lower screen (21). The bandage of the dehydration cylinder (25) has hollows which absorb water from the screens along their arcs of contact with the cylinder and which project the water towards the inside of the loop formed by the screens of the cylinder. In the feed direction of the screens and downstream of the support cylinder (26), there is arranged a receiving container (36) for the projected water. The container has a curved covering wall (40) which extends opposite the feed direction of the screens up to the interstice formed between the dehydration cylinder (25) and the screens (21,22). The reception container (36) is divided into two chambers (44,45) which extend transversally to the screens and which have separate side discharge conduits. The water supplied into the main chamber (45) through the covering wall (40) is deviated by means of blades (52) towards the direction of the discharge conduit.

摘要： A manifold-like chamber is shown having a plurality of distribution conduits in communication therewith for evenly and uniformly distributing fluid pulp stock for subsequent paper forming operations; alternate ones of such conduits communicate with the chamber as at a relatively low elevation thereof while intermediate alternate ones of such conduits communicate with the chamber at a relatively higher elevation; the distribution conduits are formed as with two straight sections joined by an intermediate single curved or bent portion to further enhance turbulence therein; the distribution conduits are further situated as have the discharge therefrom generally parallel, at least as viewed from above; edge-forming means is provided within the chamber as to thereby obtain desired flow patterns within the fluid pulp in the chamber.
