The machine comprises: folder means forming a vertically-developing continuous tubular package (1); first welding organs acting on vertical edges of the continuous tubular package (1) for closing the package (1); a first station (S1), situated below the folder means, in which second welding organs (20) operate, with a horizontal motion performed transversal of the continuous tubular package (1), to define consecutive envelopes (10); a second station (S2), underlying the first station (S1), in which the cutting organs (30) operate, with a horizontal motion which is transversal of the continuous tubular package (1) to separate an envelope (10*) occupying a lowest position in a line of the envelopes (10); drawing organs (40), for gripping the lower flap (10A) of the lowest envelope (10*) in the line, at the second station (S2), for determining a descent by a step (P) of the line of envelopes (10) and the continuous tubular package (1), in phase relation with the inoperative positions of the first welding organs and the second welding organs (20) as well as the cutting organs (30). |
