ABSTRACT:
The invention describes an apparatus for cooling and calibrating an extruded plastic profile (2) with a cooling tank (4) receiving a cooling liquid, with calibrating elements (5) disposed within the cooling tank (4) for the plastic profile (2) subjected to the cooling liquid, and with a draw-off device (7) which is disposed downstream of the cooling tank (4) in the draw-off direction of the plastic profile (2). In order to provide advantageous constructional conditions it is proposed that at least one damping device (9) is provided between the inlet-sided calibrating element (5) of the cooling tank (4) and the draw-off device (7), which damping device rests at least in sections in the zone of one circumference on the plastic profile (2).
