Abstract
In a method for producing drip irrigation tubes, a tube body is extruded, in which tube body dosing elements are inserted and are connected to the inner surface of the tube body. In the region of the dosing elements, outlet apertures are made in each case in the tube body using a laser boring device with a specified radiation intensity, through which apertures the water can escape in drops. The radiation intensity of the laser boring device is reduced between procedures. Via a laser optical system co-operating with the laser boring device, the laser beam is led in a controlled way over the surface of the drip irrigation tube, and alphanumerical symbols are burned into this surface. Production of drip irrigation tubes and their labeling can thus be carried out in one operation.
