Abstract
A headbox system for a paper-manufacturing machine includes an equalizing chamber the interior of which receives pulp stock from any suitable source and delivers this pulp stock to an outlet end of the equalizing chamber. A plurality of elongated passages, situated in a horizontal plane, respectively have inlet ends which communicate with the outlet end of the equalizing chamber to receive a pulp stock therefrom, the stock flowing along the interiors of these passages toward a slice of the headbox. A throttling plate is situated between the outlet end of the equalizing chamber and the inlet ends of the passages for throttling the flow of pulp stock from the equalizing chamber into these passages. A plurality of strips extend along the interior of the equalizing chamber and through the throttling plate into and along the interiors of the passages for guiding the pulp stock flowing through the throttling plate in such a way as to prevent variations in flow from being created by changes in the direction at which the pulp stock passes through the throttling plate into the passages.
