Extruding line for producing plastic profiles, preferably plastic tubes, has extruder, tool, calibration and succession device, where tool has aperture and exhaust in extruding direction

摘要

The extruding line has an extruder (1), a tool, a calibration (3) and succession devices. The tool has an aperture (8) and an exhaust (6) in extruding direction (7), where the flow rate of the exhaust is controlled or regulated. The exhaust is intermittently operated. An independent claim is included for a method for increasing cooling efficiency of an extruding line for extruding a plastic profile, particularly a plastic tube.
