ABSTRACT:
A film strip with a damaged end portion is repaired by using jig means for severing the strip at a fixed distance from a pre-existing locating hole to remove the damaged end portion and then attaching a pre-formed replacement end member in the same location by reference to the same locating hole. The replacement end member has the same edge configuration and hole features as the original film end portion and overlaps the severed film end to permit it to be adhesively bonded thereto.
