<p>Film transport device for discontinuously transporting a film (6) which has at least one row of regularly-distributed perforations and which is led through a film channel having a frame window for the projection of the film frame situated in front of the frame window, where transport occurs by means of a film transport sprocket wheel, the sprockets (10 to 14 and 20 to 24) of which protrude into the film perforation (71 to 75 and 81 to 85). The movement of the film is set before the projection of a film frame in such a way that the front and back flank of a sprocket (10, 21) of the film transport sprocket wheel in the direction of rotation of the film transport sprocket wheel rests against the front and back edge of at least one perforation hole (71, 85) of the film perforation when a film frame is being projected.</p> |
