Abstract
Disclosed is an apparatus and method for automatically aligning and bonding a preperforated 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 through a pair of straightening and flattening rollers to a repair station comprising a pressure roller cooperating with a sprocket roller to automatically and 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. From the repair station, the laminated tape and film pass through a pair of cooperating rollers to more firmly bond the tape and film preparatory to collection on a take-up reel.
