## CPC

- B41B 21/32: Film carriers; Film-conveying or positioning devices (film-handling means in line-composing photographic devices B41B15/32; machines with means for moving the film in its plane for photographing characters in succession B41B17/16)

## 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.

## Claims

### Claim 1

A process for saving film in a photographic device employing a continuous strip of film and a cutting blade, wherein the steps of the process comprise:
completing exposure of a first portion of film;
advancing blank film;
beginning to expose a second portion of film;
interrupting exposure of the second portion of film to stop the film when the blank film is adjacent to the cutting blade;
cutting through the blank film; and
reactivating exposure of the second portion of film.

### Claim 2 (depends on 1)

The process of claim 1 wherein the photographic device is a phototype setter.

### Claim 3 (depends on 1, 2)

The process of claims 1 or 2 wherein the blank film is a minimum length required for handling the film.

### Claim 4 (depends on 1, 2)

The process of claims 1 or 2 wherein the film advancement is monitored.

### Claim 5 (depends on 1, 2)

The process of claims 1 or 2 wherein signals indicate the completion of steps in the process.

### Claim 6 (depends on 1, 2)

The process of claims 1 or 2 wherein the first exposed portion of film is advanced into a first cassette, which is removed from the photographic device after cutting the film, and which first cassette is replaced by an empty cassette to receive the second portion of exposed film.

### Claim 7

A process for saving film in a phototype setter provided with a continuous strip of film and a cutting blade, wherein the steps of the process comprise:
exposing a first galley on the strip of film;
advancing a length of blank film equal to a minimum length required for handling the film;
beginning to expose a second galley on the strip of film;
interrupting the exposure of the second galley to stop the film advance after the first galley is inside a cassette and the blank film is adjacent to the cutting blade;
cutting through the blank film between the first and second galleys;
removing the cassette containing the first galley;
replacing the cassette containing the first galley with an empty cassette to receive the second galley; and
reactivating exposure of the second galley.

### Claim 8 (depends on 7)

The process of claim 7 wherein film advances are monitored.

### Claim 9 (depends on 7, 8)

The process of claims 7 or 8 wherein signals indicate the completion of steps in the process.

### Claim 10 (depends on 7, 8)

The process of claims 7 or 8 wherein a galley comprises a series of closely-spaced galleys.
