Abstract
Abstract A photographic filmstrip is initially coiled about a spool inside a cartridge with a trailing film end portion secured to the spool and a leading film end portion being free. The filmstrip is advanced, leading film end portion first, from the supply cartridge into a host container such that the filmstrip is reverse coiled in the host container to reduce any longitudinal curl in the filmstrip resulting from the filmstrip being wound on the spool. The trailing film end portion is released from the spool. The film in the host container can be heated to further reduce the longitudinal curl in the filmstrip.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
109 words
A method of transferring a photographic filmstrip from a film supply cartridge to a photo finishing apparatus, wherein the filmstrip is initially coiled about a spool inside the cartridge with a trailing film end portion secured to the spool and a leading film end portion being free, said method comprising the steps of: advancing the filmstrip, leading film end portion first, from the supply cartridge into a host container; reverse coiling the filmstrip, leading film end portion first, inside said host container to reduce any longitudinal curl in said filmstrip resulting from the filmstrip being wound on said spool; and releasing the trailing film end portion from the spool.
Claim 2
Independent Claim
109 words
A method of transferring a photographic filmstrip from a film supply cartridge to a photo finishing apparatus, wherein the filmstrip is initially coiled about a spool inside the cartridge with a trailing film end portion secured to the spool and a leading film end portion being free, said method comprising the steps of: advancing the filmstrip, leading film end portion first, from the supply cartridge into a host container; reverse coiling the filmstrip, leading film end portion first, inside said host container to reduce any longitudinal curl in said filmstrip resulting from the filmstrip being wound on said spool; and releasing the trailing film end portion from the spool.
Claim 3
Dependent Claim
27 words
The method of claim 1, further comprising the step of: advancing the filmstrip, trailing film end portion first, from the host container to a photo finishing apparatus.
Claim 4
Dependent Claim
33 words
The method of claim 1 wherein said step of reverse coiling the filmstrip inside the host container includes the step of reverse winding said filmstrip onto a spool located in said host container.
Claim 5
Dependent Claim
44 words
The method of claim 1, further comprising the step of heating said filmstrip, while located in said host Container, to a temperature and for a time sufficient to reduce any longitudinal curl in said filmstrip resulting from the filmstrip being wound on said spool.
Claim 6
Dependent Claim
31 words
The method of claim 4 wherein said heating step is carried out at a temperature of between about 40 and 100 degrees Celsius for between about 30 seconds and six minutes.
Claim 7
Dependent Claim
24 words
The method of claim 5 wherein said heating step is carried out at a temperature of about 80 degrees Celsius for about four minutes.
Claim 8
Dependent Claim
46 words
The method of claim 1 wherein said step of advancing the filmstrip from the supply cartridge to the host container includes the step of rotating said spool to thrust a forward end of the leading film end portion from the supply cartridge towards the host container.
Claim 9
Dependent Claim
118 words
Apparatus for transferring a photographic filmstrip from a film supply cartridge to a photo finishing apparatus, wherein the filmstrip is initially coiled about a spool inside the cartridge with a trailing film end portion secured to the spool and a leading film end portion being free, said apparatus comprising: a host containers for the filmstrip, including means for reverse coiling the filmstrip, leading film end portion first, inside said host container to reduce any longitudinal curl in said filmstrip resulting from the filmstrip being wound on said spool; means for advancing the filmstrip, leading film end portion first, from the supply cartridge into said host container; and means for releasing the trailing film end portion from the spool.
Claim 10
Dependent Claim
118 words
Apparatus for transferring a photographic filmstrip from a film supply cartridge to a photo finishing apparatus, wherein the filmstrip is initially coiled about a spool inside the cartridge with a trailing film end portion secured to the spool and a leading film end portion being free, said apparatus comprising: a host containers for the filmstrip, including means for reverse coiling the filmstrip, leading film end portion first, inside said host container to reduce any longitudinal curl in said filmstrip resulting from the filmstrip being wound on said spool; means for advancing the filmstrip, leading film end portion first, from the supply cartridge into said host container; and means for releasing the trailing film end portion from the spool.
Claim 11
Dependent Claim
26 words
The apparatus of claim 8, further comprising: means for advancing the filmstrip, trailing film end portion first, from the host container to a photo finishing apparatus.
Claim 12
Dependent Claim
32 words
