A CALIBRATION DEVICE AND A CALIBRATION METHOD, AND ALSO A CHAMBER CALIBRATOR, INTENDED FOR EXTRUSION OF PROFILES

摘要

The invention relates to a calibration device for the extrusion of plastic profiles, characterized by at least one chamber calibrator (21, 22, 23, 24), having an opening (26) and a sliding surface (27) for the profile to be extruded, with the specified chamber calibrator made with the possibility of placing in the vacuum chamber (3) with cooling water, and the heat from the extruded profile can be transferred, at least partially, to cooling water through the outer surface of said chamber calibrator, moreover, said at least at least one chamber calibrator (21, 22, 23, 24) has at least one cooling channel (29) for cooling the sliding surfaces (27), and the length (X) of the chamber calibrator (21, 22, 23, 24), defined in the axial direction corresponds to at least the height (H) and / or the width (B) of the nominal profile size. The invention also relates to a calibration method and to a chamber calibrator.
