Christe Autowind 3-disc system

Christe Autowind 3-disc platter system, made in the United States. The disc system was used to house the film for the projectors at Laugarásbíó from 2000–2010, but before that, Laugarásbíó had used so-called projection towers where the entire film was spliced onto one reel and ran through the projector to a second reel, which then had to be spliced back. When the platters were used, there was never any need to rewind because the film was projected from the core of one platter into the core of the next, and vice versa. The platter system consisted of three platters. A single film required two platters, so each assembly could hold two films at the same time. Each projector had its own disc stacker. The film went directly from one disc through the projector onto another (empty) disc. The platters were all independently controlled by sensors that determined the disc's speed. The circumference of the film on the reel required different speeds; the film on the inner spool had to turn faster than the film on the outer spool. A similar Christe reel system was used in all movie theaters in Reykjavik and Akureyri, except for the Háskólabíó, which used a Keynotone reel system with Keynotone projectors.
