An arrangement for calibrating plastic profiles, especially gutters, cable channels , comprises a calibration unit with a penetration opening with a geometry that corresponds to the plastic profile. A cooling liquid channel runs along the outer wall of the opening, and has openings, e.g. slots. An arrangement for calibrating plastic profiles, especially gutters, cable channels , comprises a calibration unit with a penetration opening with a geometry that corresponds to the plastic profile. A cooling liquid channel runs along the outer wall of the opening, and has openings, e.g. slots. A second gas carrying channel (64) runs along the inner wall (30) of the opening, and is connected to the opening via one or more openings (68). The plastic profile (18) is pressurized by the gas. The calibration unit (10) comprises a number of primary and secondary channels. |
