ABSTRACT:
The invention relates to a method for fabricating a drip irrigation pipe, comprising a pipe (5) wherein a plurality of dripping elements (4) are bound, communicating with the outside through holes formed in the pipe wall. The method according to the invention provides that the pipe (5) is extruded and the individual dripping elements (4) are bound therein by consecutively feeding the dripping elements (4) inside the pipe through the extruding head (1). The speed of the dripping elements (4) is higher than that of the pipe upon extrusion at least in the area of first contact between the pipe and the dripping elements (4). The invention also relates to a plant for implementing said method.
