HANDBOOK OF KINE M A TOGRAPH Y. 205 To make up a spool, the film which is to show last upon it is wound up backwards, and to its latter end is attached about a foot of blank spacing, either the white, black, or the blue variety. The film is then rewound right way on to the empty spool. Its title will come outermost after such winding. Affix to this title a foot of white blank spacing, and to the other end of it attach the latter end of the second film, and so on. When the last film the spool will accommodate has been wound upon it, a further ' threading up ' length of blank spacing is attached, and the reel is ready for exhibition. White blank spacing is obtainable from all film renting houses at a cheap rate. When splitting up the spool, or 'cleaning ' the films off it for sending back to the renting house, the spacing is removed and retained for further use in making up the next film program. To join film for the purpose of mending it or when attaching spacing, adopt the following routine. Cut an edge to be joined level with the top of a picture. Cut off the edge to be attached to it about one quarter of an inch or rather less below the bottom of the- picture on the end of its length. Lick the portion of the picture last cut into so as to moisten the gelatine coating. Then lay film down, gelatine uppermost, and proceed to scrape away the coating from the licked flap, till clear celluloid only is left. Dip a camel hair brush into a bottle of film cement and apply rather freely to the scraped flap, then press this flap down upon the celluloid side of the length to which it is to be joined. If rightly done both emulsion sides of film will look the same way. Shift the cemented flap rapidly into place so that the lowermost sprocket hole of the one length coincides with the uppermost on the other, and hold the two thicknesses of celluloid together for a couple of minutes. They will then be sufficiently stuck to adhere, and ten minutes more will make a tight joint of them. A reliable formula for ordinary film cement consists of com- mercial Acetone and Amyl Acetate in equal parts. In this mixture allow to dissolve sufficent clean celluloid chips (old cleaned off film will do) to impart a slight degree of viscosity. FORMULA FOR CEMENT FOR NON-FLAM FILM. Dissolve non-flam film base in chloroform till a viscous liquid results. Use in the same manner as ordinary cement, but bearing in mind that it evaporates quicker, so leaving less time for effecting registration of the sprocket holes. Where the operator's skill in film joining is not too great, he may press in the services of a film mender. This inexpensive little acces- sory accomplishes the task of correctly superposing the sprocket holes upon the two lengths to be joined, and holding all in position till dry. It is a neat device but not necessary, and certainly not time saving, in comparison with the hand mending of a good operator. Film breakages are doctored by cutting out the portion of celluloid which has been damaged and connecting together the nearest perfect pictures, in the foregoing way.
