Abstract:
1. An apparatus for calibrating an extruded plastic profile forming at least one longitudinal groove, comprising a calibrating body receiving the profile emerging from a shaping extrusion die for profiles, the calibrating body comprising a form nose with a cooling channel engaging in the longitudinal groove of the profile and extending in the direction of passage of the profile strand, and coolant bores extending transversally to the form nose and crossing the cooling channel, wherein the cooling channel which is open on both face sides is connected via a continuous slot with a receiving recess for sealing elements which are inserted from the open face sides and form the connecting openings for a flow connection between the cooling channel and associated coolant bores, which receiving recess penetrates the calibrating body in the direction of passage and extends into the region of the coolant bores.
