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.
Claims10
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.
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.
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.
