Abstract
A strip cutting apparatus such as a photographic paper cutter senses position of the blade which cuts segments from the strip. The strip is driven in a reverse direction by a predetermined number of steps after the blade has cut the strip and before the blade is retracted. This back step motion or reverse motion eliminates the occurrence of interference between the forward edge of the strip and the blade as the blade is retracted. Damage to the forward edge of the strip caused by interference with the retracting blade is thereby avoided.
