Abstract

An apparatus for transporting cartridges for exposed photographic roll films to an opening station has a downwardly sloping duct whose inlet can receive the shells of successive cartridges only in a predetermined orientation. The lower end of an inserted container or cartridge comes to rest on a first gate and the gate is retracted from the duct so as to permit gravitational descent of the inserted cartridge only if the orientation of the inserted cartridge is proper. The cartridge which descends below the retracted first gate impinges upon a cylindrical bolt which tilts the cartridge approximately 90 degrees so that the axis of the shell of such tilted cartridge is substantially horizontal before the cartridge descends onto a second retractible gate and thereupon onto a third gate in the bottom of the duct. The inclination of the duct with reference to a horizontal plane is at least 45 degrees. The cartridge which reaches the bottom of the duct is in optimum position for expulsion of the reel of a convoluted exposed photographic roll film thereon from the shell and into the range of an unwinding mechanism.
