Abstract
The invention relates to an apparatus for cooling and calibrating extruded plastic profiles with a trough which is provided downstream of a dry calibrating device and has a water bath through which the profile is guided, with plates being arranged in the trough between the face walls in order to calibrate the profile under the influence of negative pressure. In order to achieve a high production speed with a low amount of expenditure it is proposed that a sleeve encompassing the profile is provided in a section of the trough, which sleeve guides at least in a zone of the main body of the profile and that the sleeve is provided with a distance to the face walls in the longitudinal direction.
