Abstract
A calibration basket is configured for a calibration station disposed in an apparatus for producing plastic tubes. The calibration basket contains calibration tools that are successively disposed at a distance from each other across the circumference of the tube. The calibration tools are embodied as calibration strips that extend in the longitudinal direction of the tube that is to be calibrated, are disposed so as to be adjustable on displacement spindles, and are provided with one respective sliding surface that enters in contact with the tube. Recesses that are connected to discharge ports are embodied in a sliding surface and are provided within the calibration strip. The discharge ports extend in a direction of the longitudinal axis of the calibration strip.
