Abstract
Abstract A nozzle design for particular use with a fabric web treatment facility in which heated air is periodically impinged against the web through nozzles as it is processed through the facility around a plurality of elongated rolls. The design provides for ease of access into the facility for cleaning and threading the web onto the rolls by providing a pivotal mounting for the nozzles in order that they may be arcuately moved between a first operative position closely spaced to the web and a second position spaced remote therefrom. Each nozzle includes three air outlet passages extending transversely thereacross in order that the heated air flow therethrough will impinge the web at varied angles and eliminate return air velocities.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
194 words
A gas flow supply nozzle for particular use in treating a fabric web as it is continuously passed through a web treatment facility, said nozzle comprising: an elongated housing; means for mounting said housing relative to said facility and means for selectively moving said housing between a first position in an operative relationship with said web and a second position spaced remote from said web; and, at least one gas inlet area disposed adjacent one end of said housing and means for forming a plurality of gas outlet passages disposed adjacent the other end of said housing, said plurality of gas outlet passages comprising at least three of said gas outlet passages extending in a generally side by side relationship laterally across said other end wherein said first position one of said at least three passages is disposed so as to direct a portion of said gas flow generally longitudinally outward from said housing substantially transversely across said web and the other of said at least three passages are disposed so as to direct portions of said gas flow outwardly from said housing at angles to the gas flow issuing from said one passage.
Claim 2
Dependent Claim
194 words
A gas flow supply nozzle for particular use in treating a fabric web as it is continuously passed through a web treatment facility, said nozzle comprising: an elongated housing; means for mounting said housing relative to said facility and means for selectively moving said housing between a first position in an operative relationship with said web and a second position spaced remote from said web; and, at least one gas inlet area disposed adjacent one end of said housing and means for forming a plurality of gas outlet passages disposed adjacent the other end of said housing, said plurality of gas outlet passages comprising at least three of said gas outlet passages extending in a generally side by side relationship laterally across said other end wherein said first position one of said at least three passages is disposed so as to direct a portion of said gas flow generally longitudinally outward from said housing substantially transversely across said web and the other of said at least three passages are disposed so as to direct portions of said gas flow outwardly from said housing at angles to the gas flow issuing from said one passage.
Claim 3
Dependent Claim
37 words
The nozzle as defined in claim 1 wherein said mounting means comprises means for pivotally mounting said housing adjacent said one end for permitting said other end to be arcuately moved between said first and second positions.
Claim 4
Dependent Claim
51 words
The nozzle as defined in claim 1 wherein said at least three outlet passages comprise three of said passages, said one passage comprising the middle one of said three passages and said angles comprising diverging angles of approximately 30* from each side of the gas flow issuing from said one passage.
Claim 5
Dependent Claim
61 words
The nozzle as defined in claim 3 wherein said housing has a generally rectangular cross section defined by a pair of opposed side walls, a top wall and a bottom wall, said top and bottom walls converging toward each other from said one toward said other end, said three outlet passages extending transversely across said other end between said side walls.
Claim 6
Dependent Claim
34 words
The nozzle as defined in claim 4 wherein said mounting means are disposed in said side walls, said at least one gas inlet area being disposed inside at least one of said mounting means.
Claim 7
Dependent Claim
144 words
In a fabric treatment facility wherein a fabric web is passed continuously over a plurality of rolls while a gas flow is directed against said web from at least one nozzle assembly, the improvement comprising: said nozzle assembly including means for forming a plurality of adjacent outlet passages, each of said plurality extending generally transversely across said assembly in a generally side by side relationship for separating said gas flow into separate gas streams which each impinge said web generally transversely thereacross at varied angles relative to each other from said nozzle assembly, said nozzle assembly including means for mounting said assembly for permitting selective movement of said plurality of outlet passages between a first operative position adjacent said web and a second position spaced remote therefrom, said passages extending generally transverse to said web when said outlet passages are in said first position.
Claim 8
Dependent Claim
144 words
In a fabric treatment facility wherein a fabric web is passed continuously over a plurality of rolls while a gas flow is directed against said web from at least one nozzle assembly, the improvement comprising: said nozzle assembly including means for forming a plurality of adjacent outlet passages, each of said plurality extending generally transversely across said assembly in a generally side by side relationship for separating said gas flow into separate gas streams which each impinge said web generally transversely thereacross at varied angles relative to each other from said nozzle assembly, said nozzle assembly including means for mounting said assembly for permitting selective movement of said plurality of outlet passages between a first operative position adjacent said web and a second position spaced remote therefrom, said passages extending generally transverse to said web when said outlet passages are in said first position.
Claim 9
Dependent Claim
86 words
The improvement as defined in claim 6 wherein said plurality comprises three of said outlet passages in a coextensive side by side relationship, one of said outlet passages being disposed so as to direct a portion of said gas flow against said web in a direction generally normal thereto when said outlet passages are in said first position and the other of said outlet passages being disposed so as to simultaneously direct portions of said gas flow against said web at angles to said normal direction.
Claim 10
Dependent Claim
51 words
The improvement as defined in claim 7 wherein said one outlet passage comprises the center one of said three outlet passages and said other outlet passages are disposed so as to direct said portions against said web at a diverging angle of approximately 30* from each side of said normal direction.
