Abstract

A method of preparing a roll of film for development. The method involves inspecting the film for defects and imperfections as the film is unwound from a magazine. A method of preparing a roll of film for development and developing the film is also disclosed. The development of the film involves conveying the film to a development station and controlling a temperature of the development station.

Claims (35)

1. A method for preparing a roll of film for development, the method comprising:

receiving a film magazine having a roll of film therein at a film unload station of a film processing system;

extracting a tongue of said roll of film from said magazine;

unwinding the roll of film from said magazine;

cutting the trailing end of the film from said magazine;

transporting a leading end of said film to a leader splicing apparatus of the film processing system; and

splicing a leader to the leading end of said film, wherein the leader is threaded at least partially through a developing apparatus of the film processing system;

wherein during said unwinding step, the method further comprises inspecting the film for defects and imperfections.

2. A method according to claim 1 , wherein said defects and imperfections include at least one of cuts, scratches, tears and missing perforations on said film.

3. A method according to claim 1 , comprising the further steps of:

inspecting said film for proper length during said unwinding step; and

rewinding the film back into the film magazine if a defect, imperfection or improper film length is detected during said inspecting step.

4. A method according to claim 1 , comprising the further step of splicing a trailing end of said film to a leading end of a new section of leader.

5. A method according to claim 1 , comprising the further step of conveying the film to a development station adapted to develop exposed images on said film.

6. A method for preparing a roll of film for development and developing said film, the method comprising:

receiving a film magazine having a roll of film therein at a film unload station of a film processing system;

extracting a tongue of said roll of film from said magazine;

unwinding the roll of film from said magazine, wherein during said unwinding step, the method comprises inspecting the film for defects and imperfections;

cutting the trailing end of the film from said magazine;

transporting a leading end of said film to a leader splicing apparatus of the film processing system;

splicing an end of a leader to the leading end of said film, wherein the end of the leader is threaded at least partially through a developing apparatus of the film processing system;

conveying the film to a development station adapted to develop exposed images on said film; and

controlling a temperature at the development station through a heating system.

7. A method according to claim 6 , wherein said heating system includes at least a heated roller provided in a conveying path of said film.

8. A method according to claim 6 , wherein said heating system includes at least a heated roller and a heated element.

9. A method for preparing a roll of film for development, the method comprising:

receiving a film magazine having a roll of film therein at a film unload station of a film processing system;

extracting a tongue of said roll of film from said magazine;

unwinding the roll of film from said magazine;

cutting the trailing end of the film from said magazine;

transporting a leading end of said film to a leader splicing apparatus of the film processing system; and

splicing an end of a leader to the leading end of said film, wherein the end of the leader is threaded at least partially through a developing apparatus of the film processing system;

wherein during said unwinding step, the method further comprises inspecting the film for defects, imperfections and proper length.

10. A method according to claim 9 , comprising the further step of:

rewinding the film back into the film magazine if a defect, imperfection or improper film length is detected during said inspecting step.
