| 摘要 |
The invention relates to a calibration basket for a calibration station (3) in a device for producing plastic tubes (10). Said calibration basket comprises calibration tools which are successively disposed at a distance from each other across the circumference of the tube (10). The calibration tools are embodied as calibration strips (12) which extend in the longitudinal direction of the tube (10) that is to be calibrated, are arranged so as to be adjustable on displacement spindles (14), and are provided with one respective sliding surface (15) that enters in contact with the tube (10). Recesses (16, 17) that are connected to discharge ports (18) which are embodied in the sliding surface (15) are provided within the calibration strip (12), said discharge ports (18) extending in the direction of the longitudinal axis of the calibration strip (12) |
