Abstract
A method for the transport of a movie film along a film transport path, having a friction-locking connection of at least one section of the movie film to a film transport means, which is moved continuously or intermittently over a part of the film transport path, and having a pressing device which presses the movie film against the film transport means, between which and the film transport means the movie film is routed, is provided. The movie film is transported by means of feed and take-up devices, which each contain a film transport means and a pressing device and are arranged on both sides of a picture window.
Claims23
A method for the transport of a movie film along a film transport path comprising:
- frictionally engaging the movie film to a film transport means by pressing the film against said film transport means using a pressing device, which can be moved relative to the film transport means between a film insertion position and a film transport position;
- and
- continuously or intermittently moving said movie film along at least part of the film transport path wherein said movie film is moved between said transport means and said pressing device.
An apparatus for the transport of a movie film along a film transport path comprising:
- at least one film transport means for frictionally engaging a section of the movie film, said film transport means being arranged in the film transport path and connected to a drive device, said film transport means moving said movie film continuously or intermittently past a picture window;
- and
- a pressing roller for pressing the movie film against the film transport means, wherein the movie film is moved between said pressing device and said film transport means;
- said pressing roller being moved perpendicularly to the film transport path from a film transport position which brings the movie film into frictional engagement with the film transport means, to an insertion position, which is at a distance from the film transport means.

An apparatus for transporting a movie film along a film transport path comprising:
- at least one film transport means for frictionally engaging a section of the movie film, said film transport means being arranged in said film transport path and connected to a drive device,
- said film transport means moving said movie film continuously or intermittently past a picture window,
- said film transport means comprising a belt for frictionally engaging said movie film,
- said belt being placed around two drive rollers, which are separated from one another, and a spring loaded tensioning roller, which is arranged between said drive rollers, and
- a pressing roller interacting with said belt for pressing the movie film against said belt to produce a pressure force that is required for the frictional engagement between said belt and said movie film, which is moved between said belt and said pressing roller along a circular arc.

A method for the transport of a movie film along a film transport path comprising:
- frictionally engaging the movie film to a film transport means by pressing the film against said film transport means using a pressing device, wherein said film transport means and said pressing device are part of a movie film feed device;
- continuously or intermittently moving said movie film along at least part of the film transport path wherein said movie film is moved between said transport means and said pressing device:
- frictionally engaging the movie film to another film transport means by pressing the film against said another film transport means using another pressing device;
- and
- continuously or intermittently moving said movie film along at least part of the film transport path wherein said movie film is moved between said another transport means and said another pressing device, wherein said another film transport means and said another pressing device are part of a movie film take-up device, wherein the movie film is moved from a feed plate via a plurality of first deflection rollers and a first compensation roller which compensates for the intermittent film transport of the feed device past a picture window to the take-up device as well as via a plurality of second deflection rollers and a second compensation roller which compensates for the intermittent film transport of the take-up device, to a take-up plate.

An apparatus for the transport of a movie film along a film transport path comprising:
- at least one film transport means for frictionally engaging a section of the movie film, said transport means being arranged in the film transport path and connected to a drive device said transport means moving said movie film continuously or intermittently past a picture window;
- a pressing device for pressing the movie film against the film transport means, wherein the movie film is moved between said pressing device and said film transport means;
- at least another film transport means for frictionally engaging said movie film, said another transport means being in the film transport path and connected to a drive device, said another transport means moving said movie film continuously or intermittently;
- and
- another pressing device for pressing the movie film against said another film transport means, wherein the movie film is moved between said another pressing device and said another film transport means, wherein said film transport means and said pressing device form a feed device and said another transport means and said another pressing device form a take-up device, wherein the feed device and the take-up device are arranged on either side of the picture window, wherein at least one deflection roller and a compensation roller, which compensates for the film transport movement of the feed and take-up device, are arranged in the film transport path of the movie film between the feed and take-up device and feed and take-up plates, which hold the movie film.
