Apparatus for uniformly applying either liquid or foam compositions to a moving web

Apparatus for applying liquid and foam compositions to a moving web, comprising:

• a distributor to which said composition is supplied, said distributor being provided with a plurality of outlets;
• an applicator joined to said distributor means by a plurality of conduits, each conduit being connected between a respective outlet in said distributor and a respective passageway in said applicator, the passageway being arranged in spaced relationship along one side of an elongated reservoir which forms a portion of said applicator, said applicator further including means for constricting flow of said composition from the passageways into said reservoir whereby individual streams of composition discharged from said passageways are merged into a sheet-like form for passage into said reservoir, said applicator further comprising a curved blade extending along the length of said reservoir on the opposite side thereof from said plurality of passageways, said blade being arranged such that as the reservoir fills with composition, an overflow of said composition passes over the crest of said blade and moves along the blade's curvature to be deposited uniformly across said web as the web moves in a direction normal to the length of said reservoir.
