  • On the first section 24 of the molded tube 19 is on the Side of the incoming packaging material web 15 a wedge-like, plate-shaped, perpendicular from the first section 24 protruding element 28 attached, which in the direction of the second section 25 always increases in its width B.
  • the element 28 covers the entire area in which the Form shoulder 18 is connected to the form tube 19, the Form shoulder 18 has a slot 30 in the area of element 28 which is at least somewhat wider than element 28, so that between the side surfaces of the element 28 and the Slit 30 part of the hose wall can be performed can.
  • the element 28 sits in the second section 25 a rectangular extension element 29 with a constant width continued, the height of which is the maximum width B (max) of the Elements 28 corresponds.
  • the guide surfaces 32 are parallel and at a short distance from the attachment element 29 extend.
  • the guide angles are advantageously 31 even extended into the area of the element 28 educated.
  • At the level of the conveyor belts 22, 23 are two pairs of sealing jaws 33 arranged diametrically opposite one another, 34 to form the longitudinal seams 11, 12. The one The pair of sealing jaws 33 is in alignment with the element 28 or aligned with the extension element 29.
  • Each pair of sealing jaws 33, 34 has two horizontally heatable sealing jaws movable against one another 35, 36; 37, 38.
  • the pair of sealing jaws 33 is on the shaped tube 19 opposite side only in FIG. 3 shown cutting device 39 for separating an over the sealing jaws 35, 36 projecting section of the Longitudinal seam 11 arranged.
  • Aligned with the Sealing jaw pairs 33, 34 close in the conveying direction of the hose 20 each have a longitudinal seam cooling device 40 for each longitudinal seam 11, 12. Not below that in one
  • the mouthpiece of the molded tube 19 shown is a Cross seam sealing device 41 arranged.
  • the Cross seam sealing device 41 has two horizontally cross-seam jaws 42, 43 which can be moved relative to one another integrated cutting devices for separating the Bag packs 1 from hose 20.
  • the tubular bag machine 10 described above works as follows: By means of the conveyor belts 22, 23, the preferred in Roll shape stocked packaging material web 15 continuously or cyclically fed to the tube forming device 17. Of the Form shoulder 18 is then the packaging material web 15 to the Hose 20 preformed.
  • One longitudinal seam 12 is on itself known type of the two opposite longitudinal edges the packaging material web 15 is formed.
  • the other longitudinal seam 11 is of which on the first section 24 of the molded tube 19th molded element 28 formed. This happens because a portion of the tube wall through the slot 30 in the Form shoulder 18 is guided and on the side surfaces of element 28 creates.
  • the two longitudinal seams 11, 12 After the two longitudinal seams 11, 12 as described above are formed, they reach the area of the two Sealing jaw pairs 33, 34, which by means of heat and pressure Seal longitudinal seams 11, 12. If the one longitudinal seam 11 is wider than the sealing jaws 35, 36 of the Pairs of sealing jaws 33, the protruding unsealed area of the longitudinal seam 11 by means of the Cutting device 39 separated.
  • the two sealed Longitudinal seams 11, 12 are then made by the two Longitudinal seam cooling devices 40 cooled. So that for the subsequent filling process, the bsw. through a through the molded tube 19 is supplied, required Seam strength of the longitudinal seams 11, 12 reached. From that formed hose 20 are finally individual Bag packs 1 by means of the transverse seam sealing device 41, which simultaneously forms the two transverse seams 13, 14 known way separated.
