Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
114 words
A method for processing photogravure curvilinear surfaces comprising the steps of: placing a first photogravure curvilinear surface onto an etching station; rotating said first surface and simultaneously therewith spraying an etching solution thereon for a preselected period of time; removing said first surface from said etching station, then placing said first surface onto an etch terminating station; rotating said first surface and simultaneously therewith spraying an etch terminating solution thereon for a preselected period of time; and, removing said first surface from said etch terminating station, the time of residence of said surface at each of said stations being generally the same thereby prompting the sequential continuous movement of surfaces from station to station.
Claim 2
Independent Claim
114 words
A method for processing photogravure curvilinear surfaces comprising the steps of: placing a first photogravure curvilinear surface onto an etching station; rotating said first surface and simultaneously therewith spraying an etching solution thereon for a preselected period of time; removing said first surface from said etching station, then placing said first surface onto an etch terminating station; rotating said first surface and simultaneously therewith spraying an etch terminating solution thereon for a preselected period of time; and, removing said first surface from said etch terminating station, the time of residence of said surface at each of said stations being generally the same thereby prompting the sequential continuous movement of surfaces from station to station.
Claim 3
Dependent Claim
100 words
The method of claim 1 including placing a second photogravure curvilinear surface onto said etching station after removing said first surface from said etching station; rotating said second surface and simultaneously therewith spraying an etching solution thereon for a preselected period of time; removing said second surface from said etching station after removing said first surface from said etch terminating station, then placing said second surface onto said etch terminating station; rotating said second surface and simultaneously therewith spraying an etch terminating solution thereon for a preselected period of time; and, removing said second surface from said etch terminating station.
Claim 4
Dependent Claim
14 words
The method of claim 1 wherein said etching station includes a plurality of stations.
Claim 5
Dependent Claim
43 words
The method of claim 1 including the placing of photogravure curvilinear surfaces in sequence upon said etching station subsequently with the removing of said first photogravure curvilinear surface, said photogravure curvilinear surfaces in sequence following simultaneously the steps of said first curvilinear surface.
Claim 6
Dependent Claim
15 words
The method of claim 4 wherein said etching station includes a plurality of etching stations.
Claim 7
Dependent Claim
29 words
The method of claim 5 wherein said photogravure curvilinear surfaces are on each of said etching stations and said etch terminating station for substantially the same length of time.
