Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 107 words
Apparatus for applying a liquid to a moving web in patterns, comprising: (a) means for forming a liquid shroud which falls on the web and extends transversely over the web; and (b) means, disposed between said means for forming the liquid shroud and the web, for displacing the falling shroud before it hits the web to cause non-uniform application of the liquid to the web, said means comprising at least one nozzle pointed toward the shroud for blowing a fluid medium against the shroud, said at least one nozzle supported such that its discharge direction is variable, in a plane parallel to the plane of the web.
Claim 2
Dependent Claim 107 words
Apparatus for applying a liquid to a moving web in patterns, comprising: (a) means for forming a liquid shroud which falls on the web and extends transversely over the web; and (b) means, disposed between said means for forming the liquid shroud and the web, for displacing the falling shroud before it hits the web to cause non-uniform application of the liquid to the web, said means comprising at least one nozzle pointed toward the shroud for blowing a fluid medium against the shroud, said at least one nozzle supported such that its discharge direction is variable, in a plane parallel to the plane of the web.
Claim 3
Dependent Claim 19 words
Apparatus according to claim 1, wherein said at least one nozzle is supported for movement perpendicular to the shroud.
