ANORDNING FOR KALIBRERING AV EXTRUDERADE TERMOPLASTROR ELLER -PROFILER

摘要

A cooling device for liquid cooling of thermoplastics extrusions in an enclosed calibrating chamber comprises a plurality of liquid jets for spraying liquid into the calibrating chamber, a liquid receptacle for positioning beneath the calibrating chamber for receiving liquid sprayed into the calibrating chamber by the liquid jets, a pump for supplying liquid from the liquid receptacle to the liquid jets and monitoring devices for controlling the pump to maintain a liquid level selectively within the liquid receptacle or above the level of the liquid jets in the calibrating chamber. The invention also includes a calibrating device for calibrating thermoplastics extrusions and incorporating a cooling device as above mentioned.
