The invention relates to a reversing device for a film web, which has a take-off device, at least one turning-device and at least one deflecting roller, wherein the film web can be guided by the take-off device via the at least one turning device and the at least one deflecting roller to a winding device and the axes of the take-off device, the at least one turning device and the at least one deflecting roller are adjustable in angle relative to one another, characterised in that the at least one deflecting roller is formed as an expander roller having an expanding capacity which increases towards the end faces of the deflecting roller. 110100203040100203040300203040. Reversing device () for a film web () , comprising an take-off device () , at least one turning device () and at least one deflection roller () wherein the film web () is guidable from the take-off device () via the at least one turning device () and the at least one deflection roller () towards a winding device () and the axes (AA , WA , UA) of the take-off roller () of the at least one turning device () and the at least one deflection roller () are angularly modifiable towards one another ,characterized in that,{'b': 40', '42', '44', '40, 'the at least one deflection roller () is provided as an expansion stretch roller with increasing expansion stretch capability towards the end faces (, ) of the deflection roller (),'}{'b': 40', '48', '46', '42', '44', '40, 'wherein the deflection roller () comprises at least sectionally expander elements () on the peripheral surface (), which comprise an attack angle which increases in the direction of the end faces (, ) of the deflection roller ().'}210. Reversing device () according to claim 1 , characterized in that claim 1 ,{'b': 40', '42', '44', '40, 'the attack angle increases starting from, the center of the deflection roller () towards the end faces (, ) of the deflection roller () from 0° to approximately 45°.'}310. Reversing device () according to claim 1 ...
