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.
