Device for producing plastic pipe

A device for producing preferably corrugated plastic pipe from a molten plastic tube, comprising:

• an injection head for connection to an extruder, wherein the injection head is provided with a discharge nozzle device for the extrusion of the molten plastic tube, and
• several molding jaws, each having a molding surface for molding of the extruded molten plastic tube, which, for molding the extruded molten plastic tube, are arranged, each in pairs, guided by means of a drive device along a molding path in a production direction of the extruded molten plastic tube and are arranged to be returned by means of the drive device in a return device, wherein the molding jaws guided in pairs along the molding path, with their molding surfaces facing each other, form a receiving space for receiving the molten plastic tube, wherein
• 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.
