<p>The invention describes a deviation device (8) for a film web (7), which deviation device comprises at least one deviation element (9, 10, 12), which operatively interacts with the film web (7) at the point of deviation (13) of the film web (7) and guides the film web (7) on an air cushion. The invention is novel and involves an inventive step in that the deviation element (9, 10, 12) can be rotated and comprises a drive device, which sets the deviation element (9, 10, 12) into rotation so that the peripheral speed of the deviation element (9, 10, 12) differs from the transport speed of the film web (7).</p> |
