Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
223 words
Apparatus for depositing fluid on a strip top side, said apparatus comprising: a first roll means positioned to be disposed below and in contact with a strip bottom side when a strip is passed through said apparatus; a fluid coating station spaced from said first roll means, said station including: an applicator roll means positioned to be disposed above and in contact with said strip top side and to rotate in a direction opposite to the direction of rotation of said first roll means; a fluid feed means positioned in close proximity to said applicator roll means for depositing coating fluid onto said strip top side; said feed means being located on the upstream portion of said fluid coating station; a fluid metering means adjustably positioned relative to said applicator roll means to provide a predetermined gap between said metering means and said applicator roll means to provide a uniform fluid thickness on said applicator roll means which in turn will be deposited on said strip top side to be coated; said fluid metering means being located at the downstream strip portion of said fluid coating station; a second roll means spaced from said fluid coating station in a direction downstream from said first roll means; said second roll means positioned to be disposed below and in contact with said strip bottom side.
Claim 2
Dependent Claim
223 words
Apparatus for depositing fluid on a strip top side, said apparatus comprising: a first roll means positioned to be disposed below and in contact with a strip bottom side when a strip is passed through said apparatus; a fluid coating station spaced from said first roll means, said station including: an applicator roll means positioned to be disposed above and in contact with said strip top side and to rotate in a direction opposite to the direction of rotation of said first roll means; a fluid feed means positioned in close proximity to said applicator roll means for depositing coating fluid onto said strip top side; said feed means being located on the upstream portion of said fluid coating station; a fluid metering means adjustably positioned relative to said applicator roll means to provide a predetermined gap between said metering means and said applicator roll means to provide a uniform fluid thickness on said applicator roll means which in turn will be deposited on said strip top side to be coated; said fluid metering means being located at the downstream strip portion of said fluid coating station; a second roll means spaced from said fluid coating station in a direction downstream from said first roll means; said second roll means positioned to be disposed below and in contact with said strip bottom side.
Claim 3
Dependent Claim
223 words
Apparatus for depositing fluid on a strip top side, said apparatus comprising: a first roll means positioned to be disposed below and in contact with a strip bottom side when a strip is passed through said apparatus; a fluid coating station spaced from said first roll means, said station including: an applicator roll means positioned to be disposed above and in contact with said strip top side and to rotate in a direction opposite to the direction of rotation of said first roll means; a fluid feed means positioned in close proximity to said applicator roll means for depositing coating fluid onto said strip top side; said feed means being located on the upstream portion of said fluid coating station; a fluid metering means adjustably positioned relative to said applicator roll means to provide a predetermined gap between said metering means and said applicator roll means to provide a uniform fluid thickness on said applicator roll means which in turn will be deposited on said strip top side to be coated; said fluid metering means being located at the downstream strip portion of said fluid coating station; a second roll means spaced from said fluid coating station in a direction downstream from said first roll means; said second roll means positioned to be disposed below and in contact with said strip bottom side.
Claim 4
Dependent Claim
223 words
Apparatus for depositing fluid on a strip top side, said apparatus comprising: a first roll means positioned to be disposed below and in contact with a strip bottom side when a strip is passed through said apparatus; a fluid coating station spaced from said first roll means, said station including: an applicator roll means positioned to be disposed above and in contact with said strip top side and to rotate in a direction opposite to the direction of rotation of said first roll means; a fluid feed means positioned in close proximity to said applicator roll means for depositing coating fluid onto said strip top side; said feed means being located on the upstream portion of said fluid coating station; a fluid metering means adjustably positioned relative to said applicator roll means to provide a predetermined gap between said metering means and said applicator roll means to provide a uniform fluid thickness on said applicator roll means which in turn will be deposited on said strip top side to be coated; said fluid metering means being located at the downstream strip portion of said fluid coating station; a second roll means spaced from said fluid coating station in a direction downstream from said first roll means; said second roll means positioned to be disposed below and in contact with said strip bottom side.
Claim 5
Dependent Claim
44 words
Apparatus in accordance with claim 1 wherein said fluid feed means is positioned to deposit fluid at a location on said applicator roll means in which said roll means rotates in a direction opposite to the direction of fluid emanating from said feed means.
Claim 6
Dependent Claim
46 words
Apparatus in accordance with claim 1 in which said applicator roll means is adjustable relative to said first and second roll means to cause a strip to be coated to be depressed relative to the interfaces of a strip and said first and second roll means.
Claim 7
Dependent Claim
22 words
Apparatus in accordance with claim 3 in which said applicator roll means and said metering means are adjustable relative to each other.
Claim 8
Dependent Claim
15 words
Apparatus in accordance with claim 1 in which said metering means comprises a roll means.
Claim 9
Dependent Claim
22 words
Apparatus in accordance with claim 1 in which said applicator means is at least as wide as a strip to be coated.
