Abstract
In a method for producing drip irrigation pipes, a tube body is extruded from a thermoplastic synthetic material and provided with a wall. The tube body is led directly and in non-contact fashion to a pre-cooling chamber in which the tube body is pre-cooled and in which metering elements are pressed on to the wall and connected to the wall. The tube body is sized to a final diameter and further cooled in a cooling chamber.
