  • the pressing device has two for each loop the drum encircling, relatively movable press jaws, each at the same time form one jaw for the two pairs of jaws, the other jaws outside the drum, but this is deliverable, is arranged.
  • the arrangement of the press jaws mentioned makes it possible in a simple manner, in each case generated stiffening strips in the transport direction of the film web either collar-like to protrude in front or back.
  • the press jaws are on their area forming the respective jaws of different diameters Drum assigned. If, for example, as later based on the description of the figures can be seen, the first pressing jaws in the transport direction the smaller outer diameter then the stiffening strip protrudes forward like a collar. In the opposite case when the first pressing jaw in the transport direction has the larger outside diameter the stiffening strip backwards like a collar.
  • the drum is expediently provided with a sector assigned to a plurality of pressing devices Heaters assigned. This allows the legs to be sealed together Distribute loops to several stations so that the cycle time is different for each individual cycle step can be reduced. This cycle time can be reduced even further if the Sector assigned to heaters is subordinated to a sector with coolants.

  • the distance x two Foil sheet sections 2 can be quite variable, depending on the type of later from the Foil web 1 to be manufactured bag-like product.
  • stiffening strips 3 are used for the later product provided, which run transversely to the transport direction A and collar-like from the film web 1 protrude.
  • a stiffening strip 3 is formed by forming a V-shaped loop 5 formed, as can be seen from the enlarged figure 4.
  • Such a loop 5 contains two legs 6 and 7, which are sealed together when performing the method and then form a double-layer stiffening strip 3, which - depending on certain details the manufacture - can be inclined forward or backward in the direction of transport A.
  • FIG 5 a section of a packaging bag 8 is shown in perspective, which with the immediate invention has nothing to do, but which is stiff in the floor area includes peripheral edge 9, for which the stiffening strip 3 described is provided.
  • the rigid edge 9 is used in the later packaging bag 8, for example, for stacking a flat surface. This rigid edge 9 was exclusively from the film web sections 2 formed.
  • a sealable film web 1 can be seen, which shows the device in transport direction A. runs through, with only a few already mentioned in the left area of the drawing Raster marks 4 can be seen, while in the right area there are already some stiffening strips 3 have arisen.
