Abstract: A liquid distribution device comprising a tubular horizontal reservoir for holding liquid to be distributed, a plurality of passageways through the upper wall of the reservoir and communicating with an elongated space substantially enclosed by an elongated arcuate cap member extending lengthwise along the outside of the tubular reservoir, the cap member having an outlet edge which is adjustable with respect to the outside surface of the reservoir to produce an elongated narrow slit outlet through which the liquid can flow in the form of a thin sheet. This device finds its principal use in delivering wash liquid to a wet sheet of paper pulp.
