Abstract: A method is described for joining a first sheet and a second sheet of packaging material, which includes: preparing the first sheet with a first joint edge transverse to a longitudinal axis of the first sheet, and having a particular configuration with a non-straight edge; arranging the second sheet with a second joint edge transverse to a longitudinal axis of the second sheet; superimposing the first and second joint edges to join the first and second sheets so that the longitudinal axes are aligned, and the second sheet constitutes a continuation of the first sheet along the longitudinal axes; welding together the first and second joint edges superimposed on each other.
