Abstract: A blow film line and a method for operating the same relates to improving the flow rate in conventional blow film lines without compromising the production quality. The inner cooling body shows an air outlet path, with a cooling ring being embodied in a height-adjustable fashion, with a controller positioning the cooling ring in a lower area of the inner cooling body for the start-up of the facility. The cooling ring is positioned in the upper area of the air outlet path of the inner cooling body in order to achieve the steady-state production.

Abstract: The present invention provides a system and method for quickly removing and installing a filament tube and nozzle in an FFF extrusion system. The system utilizes a primary manifold that includes a cooling block, a heating block and a quick-change mechanism. This primary manifold is adapted to mate a filament tube/nozzle assembly. The quick-change mechanism, which in a particular embodiment utilizes a recessed biased-bearing arrangement, enables the filament/nozzle assembly to be removed and inserted without the use of any tools, and without causing any significant downtime for the FFF extrusion system. Once removed, the filament tube/nozzle assembly can be refurbished by a technician, trained so as not to over torque the tube/nozzle threaded interface. This refurbishment (typically consisting of a cleaning and the installation of a new nozzle) could be accomplished “off-line”, without any impact on the continued use of FFF extrusion system.

Abstract: In a method for manufacturing blown film web on a blown film line, film is heated above the takeoff device and then treated mechanically. This allows the film to be brought from initial heat to an easy-to-process temperature level with little energy. A horizontally oriented treatment roll path is provided between the takeoff and a reversing device is arranged above the takeoff. In both aspects, controlling is performed to achieve a uniform film gauge after stretching.

Abstract: An extruder is fitted with a connector for coupling and decoupling with a filament feed source, such as a filament tube. When connected, the extruder and filament tube are aligned to define a feed path for a filament. A tool rack includes a plurality of filament tubes secured within respective openings. The tool rack may facilitate coupling and decoupling operations between the extruder and filament sources. For example, the tool rack may define an insertion path that engages a filament tube during insertion, and that secures the filament tube against an excursion from the insertion path. The extruder may disengage the coupling by initiating a motion along the insertion path and then moving off of the insertion path to decouple the filament tube and the extruder. In this manner, filaments may be swapped through engaging and disengaging the extruder with different filament tubes on the tool rack.
