An automatic and integrated procedure for the continuous manufacture of a film made of polyethylene and/or plastic material, wherein the film includes at least one irrigation line integrated to the film, such that a manufactured product allows the film and the irrigation line to be deployed at the same time, the procedure including the steps of:
- a) feeding an unfolded film to a thermofusion unit comprising drag idlers through which the film passes, where silicone wheels are arranged above said drag idlers, so that they the silicone wheels touch the drag idlers and together drag the film and arrange it between the drag idlers and silicone wheels,
- b) continuously and automatically feeding the at least one irrigation line, arranging said at least one irrigation line on top of the film,
- c) feeding a film sleeve having a predetermined perforation pattern, the film sleeve being arranged over the at least one irrigation line and over the film,
- d) thermofusing peripheral edges of the film sleeve to the film using pressure by the silicone wheels, so as to weld the film sleeve and film together while leaving the at least one irrigation line;
- unbonded and retained between the film sleeve and the film.
