Abstract
An elongated manifold is supplied with either foam or liquid under pressure through a plurality of inlet ports spaced along the manifold. The manifold contacts a curved blade along a line substantially parallel to, and below the elevation of, the crest of a horizontally disposed curved blade. The manifold is provided with outlet means above the line of contact whereby foam or liquid discharged from the manifold builds up behind the blade's crest until it overflows the crest to flow as a uniform film onto a web moving past an edge of the blade.
