Abstract
Abstract A photographic film packing apparatus cuts film segments from a web of photographic film, partially overlaps the segments in a shingled manner, and conveys the segments in partially overlapping relationship into an insertion opening of a package, such as a customer order envelope. The apparatus advances the web a selected distance past a knife location, at which a knife assembly is located. The knife assembly severs a film segment from the web. The movement of the film segment is then reversed to cause a trailing edge of the film segment to be deflected downward out of the path of the leading edge of the web. The web is then advanced while the segment is maintained stationary until the web has overlapped the segment by a predetermined amount. The web and the film segment are then conveyed together toward the insertion opening until a desired cut location on the web is aligned with the knife location. The knife assembly then cuts another film segment from the web. As the apparatus continues to operate, additional film segments are partially overlapped in a similar manner until all segments corresponding to a customer's order are severed from the web. The film segments are conveyed in partially overlapping relationship into the insertion opening.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
75 words
A method of inserting photographic film segments into an insertion opening of a package, the method comprising: severing a first segment from a photographic film web; advancing the web, while maintaining the first segment stationary, to partially overlap the first segment; advancing the web and the first segment together in partially overlapping relationship; severing a second segment from the web; and conveying the first and second segments in partially overlapping relationship into the insertion opening.
Claim 2
Independent Claim
75 words
A method of inserting photographic film segments into an insertion opening of a package, the method comprising: severing a first segment from a photographic film web; advancing the web, while maintaining the first segment stationary, to partially overlap the first segment; advancing the web and the first segment together in partially overlapping relationship; severing a second segment from the web; and conveying the first and second segments in partially overlapping relationship into the insertion opening.
Claim 3
Dependent Claim
46 words
The method of claim 1 and further comprising: reversing motion of the first segment after the first segment is severed from the web to cause a trailing edge of the first segment to be positioned out of a path of a leading edge of the web.
Claim 4
Dependent Claim
21 words
The method of claim 1 wherein the package comprises a pair of generally parallel members between which the segments are deposited.
Claim 5
Dependent Claim
161 words
Apparatus for inserting photographic film segments into an insertion opening of a package, the apparatus comprising: first conveyor means for advancing a photographic film web past a knife location; knife means at the knife location for severing film segments from the web; second conveyor means for conveying the film segments in partially overlapping relationship into the insertion opening; and means for controlling the first and second conveyor means and the knife means to cause the first conveyor means to advance the web a first distance past the knife location while the second conveyor means maintains a previously severed segment stationary so that the web partially overlaps the segment; to then cause the first and second conveyor means to drive, in synchronism, the web and the previously cut segment in partially overlapping relationship toward the insertion opening until a desired cut location is aligned with the knife location; and to then cause the knife means to sever a segment from the web.
Claim 6
Dependent Claim
161 words
Apparatus for inserting photographic film segments into an insertion opening of a package, the apparatus comprising: first conveyor means for advancing a photographic film web past a knife location; knife means at the knife location for severing film segments from the web; second conveyor means for conveying the film segments in partially overlapping relationship into the insertion opening; and means for controlling the first and second conveyor means and the knife means to cause the first conveyor means to advance the web a first distance past the knife location while the second conveyor means maintains a previously severed segment stationary so that the web partially overlaps the segment; to then cause the first and second conveyor means to drive, in synchronism, the web and the previously cut segment in partially overlapping relationship toward the insertion opening until a desired cut location is aligned with the knife location; and to then cause the knife means to sever a segment from the web.
Claim 7
Dependent Claim
53 words
The apparatus of claim 4 wherein the means for controlling causes the second conveyor means to move the severed segment in a reverse direction after the segment is severed from the web to cause a trailing edge of the segment to be out of a path of a leading edge of the web.
Claim 8
Dependent Claim
41 words
The apparatus of claim 5 and further comprising: deflector means for deflecting the trailing edge of the segment to a position out of the path of the leading edge of the web as the segment is moved in the reverse direction.
Claim 9
Dependent Claim
31 words
The apparatus of claim 6 wherein the knife means has a movable blade and a fixed blade, and wherein the deflector means comprises a curved deflection surface of the fixed blade.
Claim 10
Dependent Claim
49 words
The apparatus of claim 7 wherein the movable blade has a normal position out of engagement with the fixed blade and a cutting position in engagement with the fixed blade, and wherein the segment is moved in the reverse direction when the movable blade is in the cutting position.
Claim 11
Dependent Claim
32 words
The apparatus of claim 4 wherein the second conveyor means has an entrance end positioned to receive the leading edge of the web and a discharge end positioned proximate the insertion opening.
Claim 12
Dependent Claim
21 words
The apparatus of claim 9 wherein the package comprises a pair of generally parallel members between which the segments are deposited.
Claim 13
