    Abstract: Provided are a method and an apparatus for the application of a flowable composition to fiber webs or mats, particularly oriented fiber mats, that suppresses the disruption of the fibers within the fiber mat that may result from turbulent flow in and near the point at which the flowable composition contacts the fiber mat. The apparatus includes a conveyor configured to pass through and be supported by a flood pan that allows the flowable composition to accumulate and move with the fiber mat in a machine direction in order to submerge or saturate the fiber mat as it passes through the flood pan. The apparatus also includes a recess provided in the flood pan substantially below an impact zone for redirecting the flowable composition while suppressing turbulent flow and counter-current flow within the flowable composition.
