1 The diameter of tape is controlled by diameter-control device so that the measurement   and control of diameter of tape is accurate, steady and reliable.

2 The main machine motor, shaping part and tractor all adopt frequency conversion control system and they have characteristics of easy adjustment, reliable performance, stable work condition and low energy consumption.

3 The barrel and screw of extruder adopt alloy materials after processing of harding and tempering and ionitriding, which has features of high-hardness, high wear-resistance and long service life. Screw of extruder adopts special design which makes raw materials plasticized well and the line works steadily.

4 The heating temperature of extruder and mold die head adopts automatic-control-temperature. The accuracy of controlling the temperature is high and it also economizes the energy obviously.

5 The drip irrigation tape is curled by moment electrical machinery. The drip irrigation tape can overcome the tension emerged effectively. The machine still has the equipment to calculate the length of the drip irrigation tape. The rolling length can be settled casually below 2500m (if meter prolonging is required, it can be ordered). The rolling machine has the functions of memory and automatic alarming etc.

6 The use of drip irrigation tape is especially suitable for the climatic conditions of drought, half drought and mountain region, which can reach the purpose of saving water and increasing output.

7 The whole machine is designed moderately, reasonably, beautifully and its automation degree is high.
