Abstract
Abstract Powder spraying apparatus which includes a plurality of nozzles fed by a manifold. Each nozzle is placed at an angle to the web being sprayed and has a deflector surface substantially perpendicular to the web. A curved transition zone is located between the nozzle and deflector to provide a fan-shaped powder spray.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
234 words
In a powder spray system for spraying a mixture of powder and air on the surface of web or sheet material, including means for supporting and locating the web or sheet material during the spraying thereof, the improvement comprising, in combination, a plurality of fan deflection-type nozzles disposed above said material to be sprayed and having deflection surfaces which when impinged by a powder and air mixture will form the same into a plurality of relatively flat fan-shaped sprays contiguous to one another at the surface of the material to be sprayed, each of said nozzles having an axial passage inclined downwardly at a first angle to the surface of the material to be sprayed, a deflection surface inclined downwardly at a second angle from said axial passage and a curved transition surface leading from said axial passage to said deflection surface for producing a spray of powder and air parallel with said deflection surface, the sum of said first and second angles being approximately 90* whereby the deflection surface of each of said nozzles will be disposed approximately perpendicular to the surface of the material to be sprayed so as to produce a flat fan-shaped spray directed approximately perpendicular to said surface, a manifold assembly for distributing a powder and air mixture to each of said nozzles, and powder gun means for supplying a mixture of powder and air to said manifold assembly.
Claim 2
Dependent Claim
234 words
In a powder spray system for spraying a mixture of powder and air on the surface of web or sheet material, including means for supporting and locating the web or sheet material during the spraying thereof, the improvement comprising, in combination, a plurality of fan deflection-type nozzles disposed above said material to be sprayed and having deflection surfaces which when impinged by a powder and air mixture will form the same into a plurality of relatively flat fan-shaped sprays contiguous to one another at the surface of the material to be sprayed, each of said nozzles having an axial passage inclined downwardly at a first angle to the surface of the material to be sprayed, a deflection surface inclined downwardly at a second angle from said axial passage and a curved transition surface leading from said axial passage to said deflection surface for producing a spray of powder and air parallel with said deflection surface, the sum of said first and second angles being approximately 90* whereby the deflection surface of each of said nozzles will be disposed approximately perpendicular to the surface of the material to be sprayed so as to produce a flat fan-shaped spray directed approximately perpendicular to said surface, a manifold assembly for distributing a powder and air mixture to each of said nozzles, and powder gun means for supplying a mixture of powder and air to said manifold assembly.
Claim 3
Dependent Claim
113 words
A powder spray system of the type defined in claim 1 including injection means for supplying an injection airstream to said manifold assembly, first automatically operable timing valve means for controlling the supply of powder and air so as to pulse the mixture of powder and air to said manifold assembly at predetermined timed intervals, and second valve means for controlling said supply of injection air to said manifold assembly, said second valve means being continuously open whenever an associated printing press is operating whereby said injection airstream will be continuously supplied to said manifold assembly even when said timing valve means is closed to maintain said manifold assembly free of residue powder.
Claim 4
Dependent Claim
25 words
A powder spray system of the type defined in claim 1 where said first angle is approximately 30* and said second angle is approximately 60*.
