Abstract
The method is for distributing cellulose pulp that has a 2-12% consistency. A manifoid housing is in fluid communication with distributor housing. The distributor housing has holes that are distributed along a generatrix of the distribution housing. The cellulose pulp is fed into an inlet of the manifold housing. The feed screw is rotated to convey the cellulose pulp in the transverse direction through the distributor housing. The feed screw sweeps across the holes in the distributor housing to urge the cellulose pulp through the holes. The cellulose pulp is uniformly fed through the holes and then through an inlet to dewatering drums. The cellulose pulp is run between the dewatering drums and a trough to form a pulp web. The pulp web is dewatered in a press nip formed between the dewatering drums. The dewatered pulp web is collected by a feed screw.
