摘要 |
The invention relates to a calibration device for the extrusion of profiles from plastics material, characterized by at least one tank calibrator (21, 22, 23, 24) having an opening (26) and a running surface (27) for the extruded profile, said tank calibrator being arrangeable in a vacuum tank (3) with cooling water and the heat of the extruded profile being transmissible at least partially to the cooling water via the outer surface of said tank calibrator, wherein the at least one tank calibrator (21, 22, 23, 24) has at least one cooling channel (29) for cooling the running surfaces (27), and the axial length (X) of the tank calibrator (21, 22, 23, 24) corresponds at least to the height (H) and/or the width (B) of the nominal dimension of the profile. The invention also relates to a calibration method and to a tank calibrator. |
