An apparatus for calibrating an extruded plastic profile forming at least one longitudinal groove ( 5 ), comprises a calibrating body ( 1 ) receiving the profile ( 2 ). Body ( 2 ) comprises a form nose ( 6 ) with a cooling channel ( 9 ) engaging in the longitudinal groove ( 5 ) and extending in the direction of passage of the profile, and coolant bores ( 13, 14, 26 ) extending transversally to the form nose ( 6 ) and crossing its cooling channel ( 9 ). Cooling channel ( 9 ) which is open on both face sides is connected via a continuous slot ( 10 ) with a receiving recess ( 11 ) for sealing elements ( 12 ) which are inserted from the open face sides and form connecting openings ( 19 ) for the flow connection between the cooling channel ( 9 ) and the associated coolant bores ( 13, 26 ), which receiving recess penetrates the calibrating body ( 1 ) in the direction of passage and extends into the region of the coolant bores ( 13, 14, 26 ) |
