Line cassette housing extra length film - uses single flange sided feed and take up spools with extra guides

摘要

Cassette for cine film comprising film exposure opening (11), feed spool (37), and take-up spool (38) but which contains an extra long length of film and allows it to lay flat, transport evenly and yet maintains overall cassette dimensions for those containing standard length film. The film (F) is spooled on feed and take up spools which have single side flanges (37, 38). The film is run over guides (31, 35) past the exposure opening (11) onto more guides (35, 32) to the take up spool. The cassette is light-tight, except for the exposure window.
