There are three ways of loading a center-feed spiral reel. You should practice each method (with a dummy roll), both in white light and in total darkness, and select the method that is most comfortable for you. Then perfect that method. Although the three methods are similar, there are differences that may make one method easier  for  you.  However,  before  beginning  one  of  these methods, make sure that both the reel and your hands are clean and dry. First method. Remove the film from the cassette (35mm) or separate it from the paper backing (120 or 220). The film must be handled only by the edges to prevent scratches and fingerprints. (When you work Figure 10-16.–Leading 35mm film on wire reel. with 35mm film, the tongue of the leader must be cut off to make a square end before loading the reel.) If you are right-handed, the ends of the wire spiral must be positioned on the top and pointing to the right (fig. 10-16, view A). For left-handed people, the ends of the wire spiral reel when positioned at the top must point to the left. Next, bow the film slightly concave to clear the edges of the spiral and clip or hold the film to the core (center) of the reel (fig. 10-16, view B). The film emulsion must face in or toward the reel center. The tension on the film should be firm enough to prevent the film from skipping the spiral grooves, but not so firm it overlaps  or  falls  into  the  same  groove  twice. Turn the reel, apply gentle pressure, and keep your thumb and forefinger on the film edges. This pressure produces a slight curl in the film and allows it to pass onto the edges of the reel. As you continue to turn the reel, the film straightens out and fits into the grooved spaces in the reel (fig. 10-16, view C). Apply enough tension to the film so it does not skip grooves. However, too much tension may cause the film to overlap in the same grooves of the reel. Second  method.  Prepare  the  film  as  before.  Hold the reel to be loaded on a clean working surface in your left hand with the ends of the wire spiral at the top, pointing toward the right (fig. 10-17, view A). If you are left-handed, hold the reel in your right hand with the ends of the spiral wires at the top, pointing toward the left. Hold the film by its edges in your right hand and bow it between your thumb and forefinger. With your left index finger or thumb, depress the grip clip and gently push the end of the film into the core of the reel (fig. 10-17, view B). When the reel does not have a grip clip, insert the film end about 1/4 to 1/2 inch into the reel core and hold it there with your left thumb and index finger (if right-handed). Remember, always load the reel with the film emulsion facing in, or toward, the reel core. Be sure the film is held straight at the reel center (fig. 10-17, view C). Now turn the reel smoothly in a counterclockwise direction with your left hand, and guide the film into the spiral grooves with the thumb and forefinger of your right hand (fig. 10-17, view D). Third  method.  Slowly  unwind  the  paper  backing from the film until you feel the film with your finger. Do not completely unwind the paper backing from the film. 10-22
