Calibrating Device and Method for Calibrating a Film Tube

The invention relates to a calibrating device and to a method for calibrating a film tube. An elastically deformable element (704) is secured to the sleeve (703) such that a fluid, in particular a gas, preferably air, can be introduced or discharged via a fluid connection such that a specific pressu...

Zusammenfassung:	The invention relates to a calibrating device and to a method for calibrating a film tube. An elastically deformable element (704) is secured to the sleeve (703) such that a fluid, in particular a gas, preferably air, can be introduced or discharged via a fluid connection such that a specific pressure P1 and/or a specific volume V1 is set in an area (708) enclosed by the sleeve and the elastically deformable element at a given temperature. Annular bodies (706) and (707) are arranged within the area (708), and a surface section of each annular body (706), (707) supports a respective region of the elastically deformable element (704). The elastically deformable element (704) regions which are supported by the annular bodies are located in the inlet region (711) and the outlet region (712) of the calibrating device for the film tube (713).
