    摘要: The invention describes a device for calibrating membrane tubes which are extrudable by means of an extrusion die. As characteristics it comprises a ring along the interior wall of which the extruded membrane tube can be guided as well as a cooling liquid provision appliance which can be used to provide a cooling liquid which can be conveyed to between the interior wall and the membrane tube.The ring comprises at least one open chamber in the region where the membrane tube exits the ring, wherein the at least one opening of the chamber is facing the membrane tube and is sealed with at least one permeable webbed piece. A vacuum can be applied to the chamber.
