    摘要: 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.

    摘要: A method and apparatus for winding a continuously delivered film web onto successively delivered winding tubes with a rotatably drivable contact roller, a winding station, associated with the contact roller, for the winding tube for winding the coil, a winding preparation station for receiving a new winding tube and beginning to wind the film web, and a transverse-cutting device for cutting the film web crosswise between the winding station and the winding preparation station. Associated with the winding preparation station for the new winding tube are a charger for generating an electrostatic charge of the new winding tube and a blower device for subjecting the film web to a blown air stream aimed counter to the feeding direction of the film web.

    摘要: A coextrusion adapter for an extrusion installation with extruders and a tool for producing a composite coextrusion structure of thermoplastic material. The coextrusion adapter has a central conduit with an end at an inlet side for connecting an extruder and an end at an outlet side for connecting the tool. The coextrusion adapter has at least one coextrusion conduit with an inlet end and an outlet end. A second extruder can be connected to the inlet end. At an end facing the outlet end the adjusting elements have a wedge-shape adjusting section with one wedge surface facing the central conduit and another wedge surface facing the outlet end of the coextrusion conduit. The adjusting section of the adjusting elements is pivotal around an axis extending over the width of the outlet end by the actuating drives. When an increase of the inside diameter of the respective transverse section of the outlet end occurs the corresponding transverse section of the central conduit is narrowed, and vice versa.

    摘要: A method for continuously producing flat cables with electric conductors embedded in an isolating material which are arranged at a certain distance from each other, parallel to each other. According to this invention, the band shaped conductors are guided separately in a plane forming two sides of a surface. The surface sides have insulating layers based on thermoplastic synthetic materials. According to this invention, at least one of the insulating layers which covers the surface sides is produced by extrusion coating of a thermoplastic melt.
