ABSTRACT:
A device for introducing the free end of a negative film unwound from a reel into a developing unit. The device is constituted by a clamp formed by a lower shell and an upper shell articulated about an axis parallel to the spindle of the reel. The clamp includes a cylindrical cradle adapted to receive the reel and prevent rotation of the reel during unwinding of the film. A rectilinear portion of the clamp is contiguous with the cradle and is adapted to guide the film during unwinding. The rectilinear portion includes two parallel paths for guiding the film. The rectilinear portion includes a first window for passage of a blade of a cutting member for cutting the film when the unwinding of the film is complete. The rectilinear portion includes a second window for passage of a pair of press rollers for advancing the film.
