  • the introduction of this opening can be done for example by common punching, cutting or similar processes.
  • Figure 1d shows the state in which a holding plate 5 with an associated inlet opening 6 has been applied in alignment with the common opening (4, 4 ') of the composite of wall 1 of the filter material and textile material 2. It can be seen that the passage opening 6 of the holding plate 5 has a larger diameter than the common opening (4, 4 ') of the wall of the filter bag and of the textile material. This projection, which is visible within the entrance opening of the holding plate, acts as a seal for a through the input port 6 of the holding plate 5 to be introduced nozzle of a vacuum cleaner.
  • the common bond between the holding plate 5 with the wall 1 of the vacuum cleaner filter bag on the textile material 2 for example, by an ultrasonic welding process, in which ultrasound is introduced into the holding plate by means of sonotrode and anvil.
  • the weld can be performed, for example, annularly around the inlet opening 6 of the holding plate 5, but it is also possible to weld the holding plate 5 only selectively over the textile material 2 with the wall 1 of the vacuum cleaner filter bag. It is also possible to weld the holding plate 5 over the entire surface of the textile material 2 with the wall 1 of the vacuum cleaner filter bag.
  • Both the wall 1, the textile material 2 and the holding plate 5 are formed in this example of thermoplastic materials.
  • FIG. 2 shows a further embodiment for producing a vacuum cleaner filter bag according to the invention.
  • the textile material is smaller in size.
  • the textile material is fixed only over two points 3 (for example, by welding or gluing) with the wall 1 of the vacuum cleaner filter bag.
  • the textile material 2 does not cover the bag inlet opening 4, which is in Figure 2c ) is now introduced only in the wall of the vacuum cleaner filter bag.
  • the holding plate 5 When superimposing the holding plate 5, wherein also the input opening of the holding plate 6 is brought into alignment with the bag inlet opening 4, the holding plate 5 is thus only more partially on the textile material 2.
  • the textile material 2 With the wall 1 of the vacuum cleaner filter bag (for example via a welding process), only its area is thus particularly intensified by the textile material 2 being present. This is sufficient, for example, in the case of previously known tensile loading on the vacuum cleaner filter bag.
  • FIG. 3 shows a further embodiment of a method according to the invention for producing a vacuum cleaner filter bag according to the invention.
  • FIG. 3a is identical to FIG. 1a ) or.
  • FIG. 2a the material of the wall of the vacuum cleaner filter bag is formed as a nonwoven fabric.
  • a recess A is now introduced into the wall 1 of the vacuum cleaner filter bag. This can be done for example by punching or cutting.
  • thermoplastic film F the recess A covering on the wall 1 of the vacuum cleaner filter bag, for example, by welding or gluing, fixed.
