description The web-forming section of a twin-wire papermaking machine includes a plurality of sets of web deflectors. Alternate sets are disposed on opposite sides of a pair of forming carriers between which a water suspension of fibers is disposed. Each set of deflectors has a plurality of deflectors providing forming carrier guiding surfaces spaced along a gentle convex curve. The sets of deflectors are disposed to guide the forming carriers over a tortuous path through the forming section. The tension in the forming carriers presses the outer carrier against the inner carrier at each curve, expressing water from the suspension through the carriers. The expressed water is doctored off by the deflectors.
