Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
A protected film strip comprising: (a) a developed rectangular photographic film strip having a front and back and two pairs of opposed marginal edges; and (b) a protective foil having a pressure sensitive adhesive, said foil releasably connected along one longitudinal marginal edge of said film strip, the remaining longitudinal marginal edge of said film strip extending beyond said protective foil.
Claim 2
Dependent Claim
61 words
A protected film strip comprising: (a) a developed rectangular photographic film strip having a front and back and two pairs of opposed marginal edges; and (b) a protective foil having a pressure sensitive adhesive, said foil releasably connected along one longitudinal marginal edge of said film strip, the remaining longitudinal marginal edge of said film strip extending beyond said protective foil.
Claim 3
Dependent Claim
49 words
The film strip of claim 1 wherein the protective foil includes one transparent foil adjacent the front of said strip and a matte foil adjacent the back of said film strip, each said foil including a pressure sensitive coating to permit joinder of said foils to said film strip.
Claim 4
Dependent Claim
26 words
The film strip of claim 1 wherein said film strip includes perforations and said pressure sensitive adhesive bonds only through contact with itself through said perforations.
Claim 5
Dependent Claim
44 words
The film strip of claim 1 wherein said pressure sensitive adhesive is coated in a central region of said protective foil, and said foil includes a fold line in the central region to receive and releasably secure a marginal edge of said film strip.
Claim 6
Independent Claim
92 words
A method of protecting a film strip, said method comprising: (a) providing a foil strip having a centrally positioned pressure sensitive coating; (b) providing a rectangular film strip having two pairs of opposed marginal edges; and (c) enclosing said film strip with said foil strip by folding said foil strip over onto itself and over said film strip so that one longitudinal marginal edge of said film strip is releasably retained in said foil strip by said adhesive, the remaining longitudinal marginal edge of said film strip extending beyond said foil strip.
Claim 7
Independent Claim
92 words
A method of protecting a film strip, said method comprising: (a) providing a foil strip having a centrally positioned pressure sensitive coating; (b) providing a rectangular film strip having two pairs of opposed marginal edges; and (c) enclosing said film strip with said foil strip by folding said foil strip over onto itself and over said film strip so that one longitudinal marginal edge of said film strip is releasably retained in said foil strip by said adhesive, the remaining longitudinal marginal edge of said film strip extending beyond said foil strip.
Claim 8
Dependent Claim
18 words
The method of claim 5 including the further step of severing said protected film strip at predetermined intervals.
Claim 9
Dependent Claim
64 words
The method of claim 5 wherein said foil strip includes two separate foil strips each having a pressure sensitive adhesive coating at a marginal edge thereof and wherein said method includes the additional steps of: feeding said film strip between said foil strips; and applying pressure at said marginal edges of said foil strips to releasably interconnect said foil strips to said film strip.
Claim 10
Dependent Claim
59 words
The method of claim 5 wherein said film strip includes marking notches at the marginal edge thereof extending beyond said foil strip and said method includes the further steps of: controlling the feed of said protected film strip by scanning the position of said marking notches; and severing said film strip based upon the positions of said marking notches.
