Abstract: A headbox of a paper machine for distributing stock suspension over the machine width of the paper machine onto a forming or wire section includes a headbox nozzle that extends over the machine width and that has spaced apart top and bottom lips that gradually converge from the stock nozzle inlet toward the nozzle outlet. At least one baffle that extends over the machine width is located in the nozzle between the lips and spaced therefrom. The length of the baffle in the flow direction of the stock suspension is less than twice the maximum spacing or height between the top and bottom lips of the headbox nozzle, which is the spacing between them at the tallest space, typically at the upstream entrance end of the nozzle. In addition, the length of the baffle is at most less than 50% the length of the nozzle. The baffle tapers narrower in height in the flow direction, and the angle of divergence of the top and bottom surfaces of the baffle is less than 5.degree. from the flow direction of the suspension through the nozzle.

Abstract: A method and apparatus for reducing turbulence in a pulp flow stream flowing through a paper making machine headbox includes providing lamellae disposed in a portion of the headbox. A lamella end portion is modified which provides for the flushing of a dead space formed in the wake of the lamella. The modified lamella end portion produces small flow channels which divide the pulp stream flowing past the lamella into a plurality of substreams and guides the substreams into the region of the dead space.

Abstract: A method of manufacturing a web of fibers, especially a web of paper. The pulp is uniformly distributed through an outlet over the width of the machine and along a wire or between two wires. Most of the moisture is subsequently extracted from the pulp accommodated on or between the wires at a draining point. Various amounts of retaining agents are added to the pulp at sections across the headbox and the web in order to control the level of retention sectionally.
