Patent number: 11077599Abstract: 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).Type: GrantFiled: June 8, 2016Date of Patent: August 3, 2021Assignee: Windmöller & Hölscher KGInventor: Jens Goldenstein

Publication number: 20160052192Abstract: The present disclosure relates to a method of regulating the thickness profile of inline stretched films which are manufactured in a blowing process. The films are positioned flat in a reversing take-off, which are laid and which are subsequently stretched monoaxially in a machine direction in a stretching unit. In accordance with the present disclosure, the thickness profile of the film is regulated such that a film produced by the stretching, having a deliberate thickening in its marginal region over the total film width, is of uniform thickness.Type: ApplicationFiled: November 2, 2015Publication date: February 25, 2016Inventors: Martin BACKMANN, Markus BUSSMANN, Jens GOLDENSTEIN
