Abstract
Abstract A method and apparatus for treating textile materials, such as carpet, employs an applicator station having a number of spray jets for causing a plurality of streams of fluid to be fanned out into a corresponding plurality of fan shape sheets of spray directed to the surface of a roller. The spray jets are used to spray either air, dye or gum. The roller is mounted for rotation in a dye or gum trough and the jets spray air or other fluid to cause a pattern to be formed in the dye or gum film on the roller. The pattern is transferred to the face of the carpet by a doctor blade or, alternately, directly to the carpet face. The trough may be filled with gum in which case the jets spray dye onto the film of gum picked up by the roller. The trough may also be used for dyeing in which case a different color dye is applied by the jets or multiple roll applicator stations may be provided for multi-color and tone effects. Alternately, no trough is used and dye or gum may be applied by the spray jets to the roller.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
110 words
Apparatus for dyeing a continuously moving textile web comprising a roll applicator extending the width of the moving textile web and adapted to be mounted above the moving textile web, said roll applicator including a trough for supplying liquid dye, a roller mounted for rotation in said trough and adapted to pick up the dye in a film on a surface of the roller upon rotation of the roller, a doctor blade adjacent said roller and inclined downwardly away from said roller for transferring dye from said roller to said web, and a plurality of spaced spray jets for spraying gaseous fluid on said roller to rearrange said dye film.
Claim 2
Dependent Claim
110 words
Apparatus for dyeing a continuously moving textile web comprising a roll applicator extending the width of the moving textile web and adapted to be mounted above the moving textile web, said roll applicator including a trough for supplying liquid dye, a roller mounted for rotation in said trough and adapted to pick up the dye in a film on a surface of the roller upon rotation of the roller, a doctor blade adjacent said roller and inclined downwardly away from said roller for transferring dye from said roller to said web, and a plurality of spaced spray jets for spraying gaseous fluid on said roller to rearrange said dye film.
Claim 3
Dependent Claim
27 words
The apparatus of claim 1, wherein each spray jet includes a cupped surface for fanning out the sprayed gaseous fluid into a fan shaped sheet of spray.
Claim 4
Dependent Claim
11 words
The apparatus of claim 1 wherein said spray jets are stationary.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1 further including a plurality of spray valves, each spray valve controlling gaseous fluid flow to a corresponding one of said spray jets.
Claim 6
Dependent Claim
22 words
The apparatus of claim 4 wherein said spray jets are mounted for spraying gaseous fluid onto a front side of said roller.
Claim 7
Dependent Claim
22 words
The apparatus of claim 4 wherein said spray jets are mounted for spraying gaseous fluid onto a back side of said roller.
Claim 8
Dependent Claim
30 words
The apparatus of claim 4 further including a plurality of control valves, each control valve controlling fluid flow of a control fluid to a corresponding one of said spray valves.
Claim 9
Dependent Claim
44 words
The apparatus of claim 7 further including a plurality of support members, each support member supporting at least one spray valve and a corresponding control valve and including a control fluid passage connecting said at least one spray valve to the corresponding control valve.
Claim 10
Dependent Claim
36 words
The apparatus of claim 8 wherein each support member supports a plurality of spray valves and corresponding control valves and includes a plurality of control fluid passages connecting each spray valve to the corresponding control valve.
Claim 11
Dependent Claim
31 words
The apparatus of claim 7 further including a flexible tube connecting each spray jet to a source of fluid, each said tube passing through a corresponding one of said spray valves.
Claim 12
Dependent Claim
35 words
The apparatus of claim 10 wherein each spray valve includes a spring-biased piston and a freely-rotatable ball for pinching off fluid flow in the corresponding flexible tube, said ball movable by movement of said piston.
Claim 13
Dependent Claim
46 words
The apparatus of claim 1 or 4 wherein said spray jets are disposed in a straight line and are sufficiently close together such that the spray of each spray jet on said roller extends at least to the spray of adjacent spray jets on said roller.
Claim 14
Dependent Claim
23 words
The apparatus of claim 1 or 4 wherein each spray jet includes an arcuate surface curved in two planes perpendicular to each other.
Claim 15
Dependent Claim
25 words
The apparatus of claim 4 wherein each spray jet includes a cupped surface for fanning out the sprayed gaseous fluid into a fan shaped spray.
Claim 16
Dependent Claim
140 words
Apparatus for dyeing continuously moving textile web comprising: a roll applicator extending the width of the moving textile web and adapted to be mounted above the moving textile web, said roll applicator including a trough for supplying liquid dye, a roller mounted for rotation in said trough and adapted to pick up the dye in a film on a surface of the roller upon rotation of the roller, a doctor blade adjacent said roller and inclined downwardly away from said roller for transferring dye from said roller to said web, and a plurality of spaced spray jets for spraying fluid on said roller to rearrange said dye film, said spray jets being spacd sufficiently close together such that the spray of each spray jet on said roller extend at least to the spray of adjacent spray jets on said roller.
Claim 17
Dependent Claim
140 words
Apparatus for dyeing continuously moving textile web comprising: a roll applicator extending the width of the moving textile web and adapted to be mounted above the moving textile web, said roll applicator including a trough for supplying liquid dye, a roller mounted for rotation in said trough and adapted to pick up the dye in a film on a surface of the roller upon rotation of the roller, a doctor blade adjacent said roller and inclined downwardly away from said roller for transferring dye from said roller to said web, and a plurality of spaced spray jets for spraying fluid on said roller to rearrange said dye film, said spray jets being spacd sufficiently close together such that the spray of each spray jet on said roller extend at least to the spray of adjacent spray jets on said roller.
