Abstract
Process for the manufacture of curved pipes of plastic material and device for carrying out thereof, in whose procedure a smooth pipe is first extruded and is characterized by the fact that the smooth extruded pipe, which after exiting the extrusion nozzle, goes through a cooling and calibrating device is calibrated therein, but its outer wall layer is only cooled to the thermoplastic state to such an extent that this layer supports the profile of the tube, at the same time as most of the wall of the the inner part is still in a thermoplastic state, progressively curing up to the end of its passage through the forming device and remaining completely cooled when leaving the forming device.
