Manufactured by Eastman Kodak Co. - Rochester, Monroe County NY
Assigned to Eastman Kodak Co. - Rochester, Monroe County NY

Abstract: This invention relates to a photographic roll film cartridge comprising a spool with a core and end flanges upon which is wound sensitized and protective strip material. This invention has for its object to construct such a cartridge in which the strip material is accurately and certainly located, insuring the positive engagement of the end thereof in the core of the spool and the even winding of the strip, without particular care being exercised by the user. The strip material usually comprises a band of film and protective backing or lead strip, the end of which forms the outer convolutions of the cartridge. It has been customary to bend hack a small portion of the extreme tapered end of this backing or lead strip to provide a reinforcement, permitting he easy breaking of the seal wrapped around the package. Claim: In combination, a spool with a core and a film strip with a lead portion adapted to be wound on said spool, there being a slot in the core longitudinally thereof, the end of the lead portion being tapered and having a transverse weakened line therein at that point thereof which lies a width equal to the length of said slot.
