Abstract

Extruder for plastic pipes has an extrusion head, a device for centring the pipe, a device (5) for measuring the wall thickness of the pipe, and a pipe transporter, and a control device for automatically adjusting the parts of the extrusion head controlling the pipe wall thickness, in accordance with the various wall thicknesses measured along the pipe periphery by the device (5). The extruder automatically compensates any deviations in the thickness of the pipe wall, so that a constant wall thickness is obtained; this is effected without any large increase in the cost of the appts.
