A pipe drilling device for an irrigation pipe manufacturing system including a continuous pipe feeder capable of making a pipe equipped with drippers, each dripper having a water outlet. The pipe circulates along a predetermined circulation direction (X-X′) while keeping the drippers' water outlets in a predetermined dripper orientation (Z-Z′). The pipe drilling device includes a rotary drilling unit which rotates around an axis of rotation (Y-Y′) which is orthogonal to the circulation direction (X-X′) and to the dripper orientation (Z-Z′). The rotary drilling unit is equipped with at least one drilling tool and is 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. |
