摘要： The disclosure concerns a head box for use in a paper making machine, or the like. The open channel through the head box leading to the outlet opening has at least one and more usually a plurality of guide surfaces extending through the channel. The guide surfaces are supported between the side walls of the head box and are spaced from the top and bottom of the head box and, when a plurality of guide surfaces are provided, they are spaced vertically from each other. The guide surfaces are comprised of flexible foil-like material. The guide surfaces are anchored at pivots at their upstream ends and are supported intermediate their lengths toward the outlet openings by a respective tab projecting from each side edge thereof into a receiving slot in the respective side wall of the head box. A tension spring operates in opposition to the shifting of the tab and the guide surface under the influence of the flow through the head box. The guide surface is fastened to the headbox and adjustably tensioned in a direction opposite to the flow of the pulp.
