APPARATUS ND METHOD OF MANUFACTURING PRESSURE COMPENSATOR TYPE DRIP IRRIGATION TUBES WITH DESIRED MOLECULAR ORIENTATION AND TUBES OBTAINED THEREBY

摘要

Apparatus and method of manufacturing pressure compensator type drip irrigation tubes with desired molecular orientation and tubes obtained thereby a method for manufacturing high speed pressure compensator - type drip irrigation tubes and the tubes obtained thereby having absolute radial orientation of molecular chains, the orientation imparting strength as well as flexibility to the tube material. The said method comprises extruding a tube using a plurality of extruders; blowing up the extruded tube by introducing a pressure inside the tube relatively higher than the pressure outside the tube; drawing the blown tube simultaneously to the blowing of tube.
