Abstract

A foam applicator includes a pressure manifold having a pair of adjacent inner conduits and an outer conduit which surrounds the inner conduits. The inner conduits extend axially beyond the length of the outer conduit and are connected on both ends of each to a source of foam under pressure. The outer conduit has a slotted port formed therein which extends axially along a major portion of the length thereof. One inner conduit has an effluent port formed therein which extends over the central half thereof. The other inner conduit has effluent ports formed therein which extend over the end quarter portions thereof. Foam supplied to the inner conduits under pressure pass through the effluent ports formed in the inner conduits and is evenly distributed over the entire length of the outer conduit. The foam in the outer conduit passes through the slotted port of the outer conduit and is distributed onto a moving fabric passing in contact with the pressure manifold.
