Abstract: Apparatus for repairing sprocket holes on strip material, such as motion picture film, with pressure adhesive tape having holes is provided with improved guide means for feeding material through a sprocket wheel mounted on a shaft at a repair station, an improved means for pressure bonding repair tape on material at the sprocket wheel, an improved sprocket design, and a cutting knife (attached to a knob which can be pushed in on the shaft against the force of a spring and which is used to turn the sprocket wheel) aligned with a slot in the sprocket wheel to cut the repair tape after repairs have been made, but only when the knife and a slot in the sprocket wheel are in a position where a pin in the knob that passes through the sprocket wheel can also pass through a hole in a wall that supports the shaft so the knife will cut only the repair tape, and not the tape and the material. A second embodiment uses a motor to turn the sprocket shaft, and a friction clutch at the end of the shaft to engage the knob.
