Abstract

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