In other makes of projectors, one should carefully adjust the shoes that hold the film on the intermittent sprocket. Many times, we have found the idler rollers “riding” the film and causing unnecessary damage to the film. There is no excuse for this condition when it is so easy to adjust the bracket so that the roller, or rollers, will be exactly the distance of thickness of two pieces of film from the sprocket face. In most all mechanisms, all that is necessary is a small screw driver and, after loosening the lock-nut, turn the screw to accomplish the setting of the roller bracket. Now, let us go down to the soundhead and do some checking. In order to avoid film damage here, the sprockets should be checked at least every six months; should they show considerable wear, they should immediately be replaced because worn (undercut) sprocket teeth will rip out perforations and do other damage to the film. The pad rollers should be adjusted the thickness of two films and turn freely on their shaft. If a pad roller sticks, it will soon develop flat spots and damage film. One drop of oil is all that is required each day. Use a stiff-bristle toothbrush for cleaning rollers and sprockets every day and avoid dirt piling up on them. CARE OF GUIDE ROLLERS The lateral guide rollers should also be checked every day to see that they, too, turn freely and do not develop grooves that may cause side-of-film damage or rip a splice apart while the projector is in operation. These guide rollers should also receive proper care and cleaning every day, plus one drop of oil at bearings ends. While we are on the subject of film damage, we find many situations with incorrect tension on the brake on the dummy end of the film rewinder so that the film is not rewinding tight enough, making it necessary to “pull” it tight by holding the reel statibnary while turning the other on the rewind end. Too, often film is rewound too fast, particularly when the elements are out of line, causing the film to whip against the sides, etc. Remember that brittle film is easily susceptible to damage and must be treated kindly, or you will have trouble running it in the projector. If the mechanism is not in good mechanical condition, the sprockets, shoes and gate shoes badly worn, you will really have trouble in most cases with dry, brittle film. To smn up: Film damage is caused by excessive tension on the takeup reel, worn sprocket teeth, excessive gate tension, badly adjusted sprocket idlers, sprockets not in perfect alignment, poorly made splices, excessive rewind speed and reels in bad condition. We pass along this advice on making good splices: Use a well-known brand of film cement, use a good film splicer, and carefully scrape and clean the film (both sides) before applying cement. In other words, there are three factors that are important in splicing film: good film cement and splicer, careful, intelligent work and cleanliness. First SMPTE Life Member J. W. Servies, president of the Society of Motion Picture and Television Engineers, has annoimced that the first member to be elevated to the newly created grade of Life Fellow of the Society is John I. Crabtree, eminent scientist and engineer in the photographic field. Crabtree was president of SMPTE in 1930-31 and has been a member of the Society for over 40 years dui’ing which time he served on many committees and on the board of governors. As chairman of the board of editors his guidance was instrumental in establishing the SMPTE Journal as one of the leading engineering publications of the world. As president he fostered closer liaison with other engineering societies and encom'aged the work of the SMPTE in cooperation with the American Standards Ass’n in development of acceptable standards in the field of motion pictures. Crabtree retired January 1, 1957. & Rgmar Framec tv CHrmOK iXKVKX WbiAnr ^ to SaAAiHor mmtm , ... -■ -s MAKE MONEY WITHOUT EFFORT LET US HELP YOU SELL THE PICTURE ^ ^ COST TO YOU!!
