Abstract
Stock distribution means for delivering an aqueous slurry in a papermaking machine has a tapering passage which delivers stock to a nozzle by way of several rows of channels whose inlets are in communication with the passage. The passage, the entire channels and/or the inlets of the channels are configurated and dimensioned in such a way that the resistance which the inlets nearer to the intake end of the passage offer to the inflow of stock is more pronounced than the resistance of inlets which are more distant from such intake end. This insures uniformity or substantial uniformity of the volume of stock flow in each channel in spite of the fact that the channels of neighboring rows are at least partially inclined with respect to each other and that the inlets of channels in successive rows are located downstream of each other, as considered in the direction of stock flow in the passage.
