Abstract
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. 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. Each molding jaw has a first and second guide pins and the molding jaws are guided in the guiding apparatus in that the first and second guide pins engage, with respective free ends, in first and second guide grooves of the guiding apparatus.
