Abstract (en)
The machine comprises a succession of work stations (S1, S2, S3, S4, S5) at which bags are formed from two rolls (3) of plastic film identical in width, filled, and closed ultimately by heat sealing; the bag emerges already fully fashioned from the first work station (S1), having encountered dies (12) and folders (13) by which the sides are tucked in to form gussets, and transverse heat seal plates (25) positioned to unite only the gusseted parts of the top end on either side of the mouth, in such a way as to provide a reinforced opening for the filling operation. <IMAGE>
