Abstract of the Disclosure Film edges 9, 9 of a film web 1 are sensed with sensor heads 4,4. The sensor heads 4, 4 can be motor- adjusted transversely to the longitudinal direction of the film web 1. By virtue of the displacement, signals are produced which are proportional to the displacement and which activates servo valves 8, 8. These servo valves are connected to positioning cylinders 10, 10 which are in turn connected to chain-path deflector heads 6, 6. The signals of the servo valves activate the adjustment cylinders, which then adjust the chain-path deflector heads and thus drive them in response to movement of the film edges. By virtue of the adjustment of the chain-path deflector heads, the paths of the clip chains 14, 14 are also adjusted, resulting in a variation of the grasping depths of the film strip held firmly by the clips. This brings about an oscillating movement of the film web after the feed-in into the transverse stretching frame 16.
