ABSTRACT:
Disclosed is a new and improved apparatus for aligning and bonding a pre-perforated flexible repair tape to the side edge portion of an elongated strip, such as motion picture film, having damaged sprocket feed hole perforations located therealong. Film to be repaired is fed continuously from a supply reel to a repair station comprising a grooved pressure roller cooperating with a sprocket roller specifically designed to more precisely align the preformed feed holes of the tape with the damaged feed hole locations of the film, and to bond the tape and film together in the aligned condition, the laminated tape and film thereafter being directed over an exit ramp to a storage reel for collection.
