Abstract: The invention relates to an improved clip/transport unit, characterized by the following features, among others: the clip/transport unit is divided into a clip part and a transport part, the clip/transport unit has a volume or weight fraction of at least 25% composed of one or more composite materials.

Abstract: An improved multiple-screw extruder, in particular a twin-screw extruder comprises a housing. Several housing bores are located in at least one section within the housing. The housing bores overlap at least along a partial axial length of the housing. One extruder screw is arranged in each of the several housing bores. At least two motors are provided for the at least two extruder screws. A synchronizing and torsion transmitting device, by means of which both cooperating extruder screws can be synchronized, is provided on both the inlet side and the discharge side.

Abstract: A pigmented, printable, biaxially oriented polymer film, also known as a synthetic paper, having one or more layers, is produced by (1) extruding a melt of a mixture made from crystallizable film-forming polymers, pigments or fillers, (2) allowing the extruded melt with pigments and fillers embedded in it to harden while controlling the temperature and thickness of the primary film produced followed by biaxial orientation and cooling. During this process, the temperature of the primary film is controlled in a range between its solidifying point and the temperature required for orientation such that the primary film is never cooled to a temperature below that required for orientation. Also the interval between solidification and orientation process is selected to allow crystallization of the film-forming polymer between the embedded particles of filler and pigment before orientation.
