Abstract
A device for calibrating an extruder plastic profile having a calibration unit for the profiled strand coming-out of a molding profile nozzle is described, the calibration unit having a molding body () enclosing the profiled strand, having calibration surfaces (), which press against the profiled strand, and vacuum slots (), which run in the calibration surfaces () transversely to the passage direction of the profiled strand () and are connectable to a partial vacuum source. In order to provide advantageous construction conditions, it is suggested that at least individual vacuum slots () penetrate the molding body () transversely to the passage direction () and be closed on outside of the molding body () using a removable cover ().
