  • Both the wall 1, the textile material 2 and the retaining plate 5 are formed from thermoplastic materials in this example.
  • figure 2 shows a further embodiment for the production of a vacuum cleaner filter bag according to the invention.
  • the textile material is smaller in size.
  • the textile material is only fixed to the wall 1 of the vacuum cleaner filter bag at two points 3 (for example by welding or gluing).
  • the holding plate 5 When the holding plate 5 is superimposed, with the inlet opening of the holding plate 6 also being brought into alignment with the bag inlet opening 4 , the holding plate 5 thus only rests on the textile material 2 in certain areas.
  • the textile material 2 With the wall 1 of the vacuum cleaner filter bag (for example via a welding process), only the area in which the textile material 2 is present is particularly reinforced. This is sufficient, for example, if there is a known tensile load on the vacuum cleaner filter bag.
  • figure 3 shows a further embodiment of a method according to the invention for producing a vacuum cleaner filter bag according to the invention.
  • Figure 3a is identical to Figure 1a ) or.
  • Figure 2a the material of the wall of the vacuum cleaner filter bag is designed as a non-woven fabric.
  • a recess A is made in the wall 1 of the vacuum cleaner filter bag. This can be done, for example, by punching out or cutting out.
  • thermoplastic film F covering the recess A is now fixed to the wall 1 of the vacuum cleaner filter bag, for example by welding or gluing, on the rear side of the wall 1 of the vacuum cleaner filter bag shown in perspective.
  • a textile material 2 is fixed to the film F, for example by means of four spot welds 3 .
  • the mounting plate 5 with the inlet opening 6 After the mounting plate 5 with the inlet opening 6 has been applied, the mounting plate is fixed by the textile material 2 to the film F, which forms the wall 1 of the vacuum cleaner filter bag in this area.
