<p>The invention concerns an installation for packaging liquid doses in sealed bags produced from a longitudinally open blown tubing (G), comprising a vertical frame (B), means (50, 51, 74-77) for moving along said blown tubing (G), a pipe (41) supplying said liquid, means for welding (38, 39) said opening, means for welding (68) the opposite edges of said tubing (G) beneath the end of said pipe (41) and cutting means (42, 43, 72, 73). A first welding and cutting station (3) is arranged on either side of said pipe (41), to provide first weld seams and cuts, a second welding and cutting station (4) is arranged beneath the end of said pipe (41) to produce transverse weld seams to link the two adjacent ends of the first weld seams located on either side of said feeding pipe of two adjacent pairs of said first weld seams and to form cut-outs.</p> |
