ABSTRACT:
Method and apparatus for testing wind and trip in camera units for use with photographic film. Each camera unit encloses and defines a film path and includes a film driven preset member and a film spindle. The preset member extends into the film path. In the method, the film spindle of the camera unit is wound; and, in tandem with the winding, a film surrogate is propelled along the film path from a position upstream from the preset member to a position downstream from the preset member. During the propelling, the film surrogate is maintained in the film path.
