Beschreibung
Zusammenfassung:	The invention relates to a device and a method for calibrating a blown film (6), said device comprising: a tubular region with at least one inner wall (55), through which region the blown film can be passed; a liquid reservoir (82), which can be used to provide a liquid and which is situated above the tubular region, the liquid being guidable between the inner wall (55) and the blown film; and a suctioning device (B), situated below the tubular region, for suctioning off at least part of the liquid from the blown film. At least one liquid-permeable element (92) is provided, said element surrounding at least parts of the periphery of the blown film (6). This device permits the distance of the liquid-permeable element from the main axis of the blown film to be altered.
