In the adapter the films are superimposed to bring them into emulsion-to-emulsion relationship, with the orthochromatic film nearest the lens. This superimposition is accomplished by looping and laterally displacing the orthochromatic film as shown Fig. 3 (Fig. 2). In this relationship the films emerge from the adapter and enter the camera.
