1361675 Cinematography; splicing H HERMANN 13 Aug 1971 [10 April 1971] 38201/71 Heading G2E A film splicing assembly includes a backing tape 1 carrying a number of splicing patches 2 coated with adhesive, having perforations 3 corresponding to those of the films to be joined and having tabs 5 removably connected by strips 4. The tabs 5 have perforations 6, 6a, 7, 7a for co-operating with bosses 14, 14a, 20, 20a on a film splicer Fig. 2. The patches 2 are disposed in pairs on the tape 1, the patches of each pair being intended for joining opposite faces of the films. A film splicer includes an upper part 9 with a slide 34 carrying a film cutting blade (not shown), which can project through slit 18, and bosses 20, 20a, a lower part 8 with bosses 14, 14a and film guiding part 11 with a trough 21 for receiving the ends of the films to be spliced. The trough 21 has flared ends, teeth (28) for engaging the films near their ends and clamping cams (41) for holding the films, Fig.4 (not shown). In operation films are inserted from opposite ends of the trough 21, their ends slightly overlapped and this overlap trimmed off by the cutting blade, trimming occurs with the parts 8, 9, 11 closed together. The splicer is then opened (as in Fig. 2) a pair of patches 2 fitted by their tabs 5 to the bosses 14, 14a, 20, 20a, the splicer closed so that the patches 2 adhere to the film, the spliced film is then drawn out and the tabs 5 removed. |
