Apparatus for dry cleaning exposed films |
摘要 |
An apparatus for cleaning exposed film includes a dry cleaning unit including at least a first dry cleaning station comprising an ionization unit having an electrostatic discharge device and means for removing discharged dust particles from the film. A roller driven by a drive motor draws the film from an unwinding reel through the dry cleaning unit. A film take-up reel driven by a controlled drive motor is disposed downstream of the driven roller. The controlled drive motor is controlled so that a tensile force acting on the film remains uniform as a diameter of the film winding on the film take-up reel varies. A satisfactory cleaning of the film is thus achieved, even when cleaning old and heavily-soiled films, together with a reliable take-up of the cleaned film without a danger of film breakage in the film cleaning apparatus.
