Summary[edit]
| Description |
Français : Équipant un appareil de projection cinématographique du début du XXème siècle, cet obturateur cylindrique sert à cacher le court instant où la pellicule se déplace d'un photogramme au suivant, et permet en plus sa ventilation poussée lorsqu'elle passe dans le faisceau très chaud de la lampe à arc. |
