Claims (4)

Patent claims: 1. Cinematographic device, in particular for narrow film projection, with in the direction of film travel single gripper transporting in front of the picture window, characterized, . that a drag gripper device with a second gripper tooth is provided behind the picture window is, which keeps a feeler element arranged in front of the transport gripper inoperative until the end of the film is guided past him, but then comes into gear connection with the transport gripper and the last piece of film gradually out of the picture window film guide via its' drag gripper tooth pulls. 2. A cinematographic device according to claim 1, characterized in that the ao drag gripper device has a resiliently abutting pivot lever (4) on the edge of the projection film (13) which on the one hand deceives a slide (7) articulated with a drag gripper / ahn (9) and, on the other hand, is pivotably coupled to a stop hook (11) which is rotatably mounted on a wall part fixed to the housing and protrudes with its one end (lie) in the normal position into the movement area of the drag gripper tooth (9). 3. Cinematographic device according to claim 1 and 2, characterized in that the pivot lever (4) as a film probe member has an angled inclined surface (4a) with which it reaches through an opening (2c) of a film runner (la) . 4. Cinematographic device according to claim 1 to 3, characterized in that the slide (7) carrying the drag gripper (9) is connected to the pivot lever (4), preferably via pin-slot guides (4 b, Ta), and opposite it in the Film transport movement in the opposite direction is tensioned by spring force (8).
