Abstract: For distributing stock evenly across the face of a tube bank (30) in a papermaking machine, the stock supply header (14) has an increasing change in cross-sectional area per unit width traveling from the inlet end (16) to the recirculation end (18) of the header (14). The header top wall (22) converges toward the bottom wall (24), while the rear wall (26), converges toward the front wall (28). The change in a cross-sectional area down the header (14) from the inlet end (16) to the recirculation end (18) is thus closely matched to an ideally parabolic shape.
