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 i…
