Abstract
Abstract Apparatus for uniformly distributing liquid to a moving web or the like including a housing having side walls with elongated liquid exit slits formed therein. Curved deflector plates are positioned adjacent to the exit slits to direct fluid exiting therefrom toward the moving web. Baffles are provided within the housing defining openings through which the liquid must pass prior to exiting from the exit slits. The baffles are positioned in such a manner as to agitate the liquid prior to its reaching the exit slits.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
160 words
Apparatus for uniformly distributing liquid to the surface of a moving web, said apparatus comprising a housing having side walls and a bottom wall, said housing being disposed above said surface and having an interior accommodating said liquid, at least one of said side walls having an upper wall section having a curved bottom end and a lower wall section having a narrow top end, said ends spaced from one another to define an elongated narrow slit extending across said web surface and positioned above said bottom wall, said curved bottom end extending from the housing interior over said narrow top end and at least partially defining a curved liquid deflection surface extending from said elongated narrow slit externally of said housing interior and adapted to direct liquid exiting in a generally horizontal direction from said housing interior through said exit slit downwardly toward said web surface in a thin stream conforming to the dimensions of said elongated narrow slit.
Claim 2
Dependent Claim
160 words
Apparatus for uniformly distributing liquid to the surface of a moving web, said apparatus comprising a housing having side walls and a bottom wall, said housing being disposed above said surface and having an interior accommodating said liquid, at least one of said side walls having an upper wall section having a curved bottom end and a lower wall section having a narrow top end, said ends spaced from one another to define an elongated narrow slit extending across said web surface and positioned above said bottom wall, said curved bottom end extending from the housing interior over said narrow top end and at least partially defining a curved liquid deflection surface extending from said elongated narrow slit externally of said housing interior and adapted to direct liquid exiting in a generally horizontal direction from said housing interior through said exit slit downwardly toward said web surface in a thin stream conforming to the dimensions of said elongated narrow slit.
