Drip Tape Line: New extrusion line from Cincinnati Extrusion for producing irrigation pipes

摘要

In cooperation with the American company Drip Research Technology Services USA Ltd., San Diego. California, the Vienna plastics machine manufacturer Cincinnati Extrusion GmbH has developed a new process for continuous production of irrigation pipes. The line concept is a simple and economical alternative to conventional methods and is of special interest to all markets with constantly rising demand for irrigation systems, Besides North and South America, these markets are also to be found in southern Europe, the Middle East and China. The development of this new extrusion line design began with the idea of replacing the so-called "drippers" placed on the inside of conventional irrigation pipes with a continuous, embossed PE tape. In the conventional intermittent approach. the injection-molded drippers are inserted through the rear of a crosshead die at defined intervals into the just produced pipe. The mechanical insertion of these parts requires an elaborate high-precision mechanical system. At the end of the pipe extrusion line, a hole is punched in the pipe at the exact point where the dripper has been attached.
