ABSTRACT:
A machine which is capable of cleaning and inspecting motion picture films with respect to splices, tears or breaks, sprocket hole elongation, or the like, includes a supporting frame, a rewind motor assembly and rewind reel, a take up motor assembly and take up reel, and motor control means for controlling the rewind and take up motor assemblies, the motion picture film extending between the rewind reel and take up reel. The machine frame has provision for selectively receiving separate and independent modules along the motion picture film between the rewind and take up reels. Each separate module has a panel which is removably securable to the frame. One of the modules is a motion picture film cleaning module, another is a motion picture film inspecting module, and still another is a capstan module. Each module may differ in construction and operation and be substitutable one for another, although certain modules are preferred. Any one or more or all of the cleaning, inspecting and capstan modules may be removably secured to the frame.
