Beschreibung
Zusammenfassung:	A device for producing plastic pipes may include an extruder with a die head and a corrugator, into which a molten plastic tube is introduced by means of the die head to mold the plastic pipe, wherein the corrugator has a molding section, in which molding jaws are guided in pairs in the production direction. In an inlet section of the corrugator, the molding jaws are brought together to form molding jaw pairs towards the start of the molding section, and in an outlet section of the corrugator, the molding jaw pairs are moved apart from each other from the end of the molding section. The guiding apparatus has a guide and/or temperature-control element apparatus having a temperature-control medium channel apparatus through which temperature-control medium can flow, and a guide and/or temperature-control surface apparatus, which faces the outer side of the molding jaws passing through, transferring heat.
