Device and method for drilling an irrigation pipe at dripper location

Method for drilling an irrigation pipe equipped with drippers having a water outlet, said pipe continuously running along an irrigation pipe manufacturing system, comprising

• keeping said irrigation pipe circulating along a predetermined circulation direction X-X′ while keeping the drippers' water outlet in a predetermined dripper orientation Z-Z′,
• providing a rotary drilling unit equipped with at least one drilling tool performing a rotating motion around its own longitudinal axis, and being distant from the pipe so that said drilling tool is able to drill a hole in the pipe wall at a location of a dripper when the angular position of the drilling tool corresponds to the closest position from the pipe,
• making said rotary drilling unit to rotate around an axis of rotation Y-Y′ which is orthogonal to said circulation direction X-X′ and to said dripper orientation Z-Z′,
• drilling holes in the pipe wall at each location of a dripper when the angular position of the drilling tool is the closest from the pipe.
