20110064836 | DEVICE FOR PRODUCTION OF DRIP IRRIGATION TUBES - A device for producing a drip irrigation tube comprises an extrusion apparatus for extruding a tube body made of a thermoplastic synthetic material, a device for inserting metering elements in the extruded tube body and for pressing and connecting the metering elements in the tube body. Furthermore, a calibrating device for adjusting the extruded tube body to the desired outer shape is provided. Provided in addition are cooling devices, for cooling the extruded tube body with coolant, and a drilling device for making outlet holes in the vicinity of the metering elements for the water. The device for pressing and connecting the metering elements in the tube body is disposed in a pre-cooling chamber. Disposed after the pre-cooling chamber is a further chamber, in which the drilling device is disposed. Disposed following the further chamber is the main cooling chamber, the calibrating device being inserted between the further chamber and the main cooling chamber. Besides an exact placement of the outlet holes in the tube body, a savings in energy during carrying out of the drilling operation is also achievable by means of this configuration. | 03-17-2011 |
20110056619 | METHOD FOR PRODUCING DRIP IRRIGATION PIPES - 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. | 03-10-2011 |
