54 Motion Picture COATING FILM. The coating of the film by the manufacturers of film stock is an interesting process, although concealed from the public generally. However, to reveal the method avails but little, as the most of success depends upon the formulae and the minutise of the process. The film is slowly drawn, in the coating machine, beneath a hopper with a narrow lateral slit in such a way that the full width of this great web, 22 inches wide and anywhere from 400 to 600 feet long, is evenly coated. As it is drawn from under the mouth of the emulsion hopper it is carried along gradually with an ever-decreasing movement until it hangs in great folds from a little trolley track near the ceiling of the drying room. Another method consists in carrying the emulsion hopper along over the surface of a stone or glass top table 200 feet long, upon which the celluloid has been spread and dried. After coating, the film is rolled up and passed through a machine which splits it into the proper width, the length, in the meantime, being measured by a little instrument which accurately records the number of feet passed.
