1184 HANDBOOK OF PROJECTION FOR faults only, or may be set to permit the examination of every splice in the film. If so set, then every splice which passes the detector automatically stops the mechanism, which must be started again by the attendant after the splice has been examined. If set for faults only, then the mechanism stops automatically when anything in the nature of a fault passes the "detector." Even the splitting of one division between two sprocket holes will act to stop the mechanism, which must be started again by the attendant. The speed of inspection is 225 to 250 feet per minute. There are no sprockets. Nothing touches the emulsion side of the film in its passage through the mechanism. It rewinds the film into a firm roll, without slippage, hence causes no "rain" in the process of inspection and handling by the machine. The machine is one of precision, yet is dependable in that it is quite simple, easily handled and unlikely to get out of order. There are several advantages incident to thorough film inspection which the average theatre manager and projectionist do not ordinarily consider. For example, thorough inspection and repair of film reduces the fire hazard very decidedly. In fact, it may almost be said to eliminate it since in at least nine cases out of ten film fires have their inception, in one way or another, in faulty film. Thorough film inspection is an insurance against programme interruptions. They also, if carried out in all theatres, are in the nature of an insurance against receiving films in poor condition, to the consequent damage oi your own show. That really sounds like a selling talk, but whatever it sounds like, it is just cold facts.
