ABSTRACT:
A papermaking machine has a stock manifold or headbox which is tapered in the machine direction. Paper stock flows through a bank of tubes from the stock manifold to a slice for injecting stock onto a forming wire. Each tube in the tube bank extends in a plane which is substantially parallel to the direction of motion of the paper web being formed. The tubes are connected to the interior of the headbox manifold along a stock supply wall. A plurality of supply conduits are connected to the supply wall and discharge emollients such as chemicals and fillers into the manifold where they are immediately drawn, together with the stock, into adjacent tube ends which feed the stock and added chemicals to the slice for forming a paper web.
