  • a folding is realized, which consists of a first and second pleat leg, wherein the second pleat leg has a greater leg length and forms a projection with respect to the web.
  • a welding of the upper web with the lower web wherein the lower web is welded in the edge region of the supernatant with the longitudinal edges of the upper web then takes place.
  • it is then only necessary to introduce transverse welds into correspondingly prescribed intervals and to carry out a separation.
  • the great advantage of the method according to the invention is the fact that due to the fact that First, a folding is introduced into the sub-web, can be formed by introducing punch-outs into the fold and corresponding welds, inclusions, which then lead in the everted state to outer folds in different geometries.
  • Ausyogülpare outer folds can be realized in the fully everted state in trapezoidal and triangular shape, so that an adaptation of the dust filter bag to the different geometries of the dust collecting spaces of different vacuum cleaner models is possible.
  • the method according to the invention can be further developed such that a separation is carried out simultaneously with the transverse welding to form the flat bag. It is also advantageous if, in order to support the folds, preliminary breaks are introduced into the lower web.
