Abstract

An arrangement (2) for feeding stock to a headbox (1) in a papermaking machine, which comprises at least one stock header (3) with an inlet for receiving stock into the header and a plurality of stock header outlets (5) permitting stock to leave the header. For each stock header outlet (5) there is a stock conduit (7, 8, 9) downstream of the stock header outlet permitting stock to pass from the stock header outlet (5), through the conduit (7, 8, 9) to the inlet of the headbox. The arrangement includes a dilution header (30) for feeding a diluent such as water to a plurality of stock conduits. The dilution header has an inlet (31) for receiving a diluent into the dilution header (30) and a plurality of outlets (32) permitting the diluent to leave the dilution header. For each dilution header outlet (32), there is a diluent conduit (33) permitting the passage of a diluent from the dilution header (30) into a stock conduit (7, 8, 9). According to the invention, the diluent is fed into a stock conduit (7, 8, 9) at a location immediately downstream of a stock header outlet (5) and the stock header together with the stock header outlets (5) is designed such that the velocity of the stock flowing through the stock header (3a, 3b, 3c) is substantially equal to the velocity of the stock in an upstream end (10, 11, 12) of the stock conduits (7, 8, 9).
