Abstract
Abstract In a continuous process for inserting a scroll of interwound photographic film and backing paper into a film cartridge comprised of two cartridge halves, an assembled-but-unsealed cartridge is presented to a movable cartridge carrying fixture having manipulable clamping members for engaging the respective cartridge halves. The cartridge, while on the fixture, is incrementally advanced through a series of work stations as the cartridge halves are separated from each other, by means of the fixture, for scroll insertion purposes. By means of the fixture the cartridge halves are maintained in a fixed predetermined relationship to facilitate re-assembly following insertion of the scroll.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
148 words
The method of loading a wound photographic element scroll into a film cartridge of the type having body member means for defining a major portion of a generally cylindrical supply compartment having a central axis and cover member means for defining an end wall of said compartment, said method comprising the steps of: engaging the respective member means of an assembled cartridge; separating said member means by displacing said member means relative to each other in a direction generally parallel to said axis; positioning said body member means at a scroll loading station, and relatively moving said cover member means away from said axis to clear the opening to said supply compartment; inserting said wound scroll into said supply compartment; and reassembling said member means by realigning said cover member means along said axis and by then relatively moving said member means toward each other along said axis.
Claim 2
Independent Claim
148 words
The method of loading a wound photographic element scroll into a film cartridge of the type having body member means for defining a major portion of a generally cylindrical supply compartment having a central axis and cover member means for defining an end wall of said compartment, said method comprising the steps of: engaging the respective member means of an assembled cartridge; separating said member means by displacing said member means relative to each other in a direction generally parallel to said axis; positioning said body member means at a scroll loading station, and relatively moving said cover member means away from said axis to clear the opening to said supply compartment; inserting said wound scroll into said supply compartment; and reassembling said member means by realigning said cover member means along said axis and by then relatively moving said member means toward each other along said axis.
Claim 3
Dependent Claim
85 words
Apparatus for use in loading a wound photographic element scroll into a film cartridge of the type having body member means for defining a major portion of a generally cylindrical supply compartment having a central axis and cover member means for defining an end wall of said compartment, said apparatus comprising: a. a scroll loading station; b. fixture means for engaging the respective member means of an assembled cartridge, and for relatively positioning said member means with respect to each other, said fixture means comprising;
Claim 4
Dependent Claim
85 words
Apparatus for use in loading a wound photographic element scroll into a film cartridge of the type having body member means for defining a major portion of a generally cylindrical supply compartment having a central axis and cover member means for defining an end wall of said compartment, said apparatus comprising: a. a scroll loading station; b. fixture means for engaging the respective member means of an assembled cartridge, and for relatively positioning said member means with respect to each other, said fixture means comprising;
Claim 5
Dependent Claim
51 words
means for positioning said body member means at said scroll loading station; and c. means at said scroll loading station for inserting said scroll into said supply compartment; and d. means for reassembling said members including means for moving one of said members in a direction generally parallel to said axis.
Claim 6
Dependent Claim
51 words
means for positioning said body member means at said scroll loading station; and c. means at said scroll loading station for inserting said scroll into said supply compartment; and d. means for reassembling said members including means for moving one of said members in a direction generally parallel to said axis.
Claim 7
Dependent Claim
41 words
The invention of claim 2 wherein said body member means further defines a takeup compartment for housing a movable takeup core and said apparatus includes means for retaining said core in said takeup compartment during said separating of said member means.
Claim 8
Dependent Claim
45 words
The invention of claim 3 wherein said cover member means further defines a takeup compartment end wall having an aperture alignable with said takeup core and said retaining means comprises means for directing a flow of fluid through said aperture and against said takeup core.
Claim 9
Dependent Claim
171 words
Apparatus for use in loading a wound photographic element scroll into a film cartridge of the type comprising body member means for defining a major portion of a generally cylindrical supply compartment having a central axis and including a first supply compartment end wall and cover member means for defining a second supply compartment end wall, said apparatus comprising: a scroll loading station; first clamping means for engaging said first end wall; second clamping means for engaging said second end wall; means for separating said clamping means including means for displacing one of said clamping means in a direction generally parallel to said central axis and for relatively moving said one clamping means away from said axis; means cooperable with said clamping means for positioning said body member at said scroll loading station; means at said scroll loading station for inserting said scroll into said supply compartment; and means for reassembling said cartridge including means for moving one of said clamping means in a direction generally parallel to said central axis.
Claim 10
Dependent Claim
171 words
