  • a third embodiment is shown, which is not part of the invention.
  • another type of bag 10 is used, namely a so-called side-folding bag.
  • This type of bag 10 is known as such from the prior art.
  • the bag 10 is provided with a longer bag flap 16 which, as in the first two embodiments, is attached to the bag flap 16 with a first portion 23 and projects beyond a rim 24 of the bag flap 16 with a second portion 25 and contour following the bag 10 and attached thereto.
  • Both the tape 19 and the band 21 are mounted starting from the front side 17 of the bag in the region of a bottom side 83 located between front side 17 and rear side 18. This is done according to Fig. 27 to 29 while the bag 10 lies flat on a conveyor belt 31 and the front 17 for attaching the first portions 23 of tape 19 and band 21 facing upward.
  • the transport belt 31 has no recess 57, since the blank does not have to be placed in the region of the underside of the bag 10.
  • the bag 10 Analogous to Fig. 6 to 8 the bag 10 abuts a slider 39 on one side. With a hold-down 41, the bag flap 16 is held in position. A blank is placed from above ( Fig. 27 ) and folded by means of a folding member 84 in the region of the substantially flat bottom side 83. This is done by gradually lowering the folding member 84 (FIG. Fig. 28 ).
  • the slider 39 is moved laterally in the direction of the folding member 84, so that the bag 10 or its bottom side 83 pressed against the folding member 84 and the blank on the bottom side 83 is attached over the entire surface ( Fig. 29 ).
  • the folding member 84 takes over as far as part of the tasks of the guide 40 from the first two embodiments.
  • the dimensions of the folding member 84 are preferably selected so that the blanks in the region of the second portion 25 can rest against the folding member 84 essentially over the whole area.
  • both the tape 19 and the band 21 are attached in one step by the same folding member 84 on the bottom side 83. It is also conceivable that, as in the first two embodiments, first in a first step, the tape 19 and then in a second step, the banderole 21 is attached to the bag 10.
