ABSTRACT:
After exposing one galley on a continuous strip of film, advance a length of blank film equal to the minimum length required for handling the film. Then begin to expose a second galley on the film. After the first galley has advanced into a cassette and the blank film is adjacent to the cutting blade, interrupt the exposing of the second galley to stop the film advance. Cut through the blank film, remove the cassette containing the first galley, and replace it with an empty cassette to receive the second galley. Reactivate exposure of the second galley. The process may be repeated between any galleys thereafter and between series of closely-spaced galleys exposed on the same strip of film. Advances of the film must be monitored for required distances and signals may be given between steps in the process.
