ABSTRACT:
The fiber orientation of fourdrinier laid machine made paper is simulated with a bench top handsheet mold by means of a two-axis flow convergent nozzle asymmetrically positioned in the slurry reservoir box of the mold. When a pulp slurry is drained of water, a strong flow stream vector component parallel with the forming wire plane is generated within the flow stream as the slurry flows inductively over the nozzle surfaces and from the nozzle throat.
