  • Method of producing a film made of a thermoplastic material
    Patent number: 7604770
    Abstract: A method and a device for producing a film made of a thermoplastic material, wherein a plastic melt is blown up into a film bubble and is shaped into a desired film by a calibrating arrangement, and a downstream arranged flattening device. For providing as contactless as possible a guidance, calibration and flattening, film guidance elements are used with a laminar uniform air cushion between the film guidance element and the surface of the film bubble, without contact between the surface of the film bubble and the film guidance element.
