Abstract
The invention relates to a cooled calibrating device for a plastic extrusion facility, comprising a housing () receiving a cooling liquid () and calibrating guides () through which a plastic profile () is passed, in addition to inlet and outlet holes () having attached lines for the cooling liquid, wherein an area () free of liquid and filled with air remains above the level of the cooling liquid. An outlet hole () for the cooling liquid is arranged at the height of the cooling liquid level () in the calibrating device so that the cooling liquid can flow out without an additional pump. An outlet line () attached to the outlet hole extends vertically and ends in a cooling liquid reservoir () that is subjected to an external atmosphere, wherein a compact liquid column () is formed in the outlet line ().
