Abrégé

The invention relates to a device for producing plastic pipe from a molten plastic tube. The device comprises a injection head for connection to an extruder for the extrusion of the molten plastic tube and several molding jaws in each case having a molding surface for the molding of the extruded molten plastic tube, which, for molding the extruded molten plastic tube, are arranged, in each case in pairs, guided by means of a drive device along a molding path in the production direction of the extruded molten plastic tube. The molding surface in each case partially encircles a receiving space for receiving the molten plastic tube. According to the invention, at least one of the molding jaws has a sensor device which comprises at least one sensor with a data-capturing sensor head, which is arranged such that its capture area comprises an area of the molding surface and/or an area of the receiving space.

Abrégé

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.
