Abstract
A continuous film developing machine adapted for processing photographic films of different formats and different patterns of film perforations, includes a series of treatment baths arranged consecutively in the path of movement of the processed film. Dosing devices with feeding valves adjust the amount of additional filling into the respective baths. A set of pneumatic sensors in the form of air nozzles is arranged opposite one side of the processed film strip, whereas a corresponding set of pressure air operated switches is arranged at the other side of the strip opposite respective nozzles. The switches detect the air jets passing through the perforations characteristic of each film format and actuate relay controlled switches which in turn put into operation a dosing device pertaining to the format of the processed film.
