  • the two outer layers consist of a fleece - made of nylon fibers - which are welded together. These outer layers have relatively high strength both in the machine direction and across it.
  • the vacuum cleaner bag as such is designed firmer in terms of its nature, in particular to meet the suction.
  • the invention thus presents the problem of providing a vacuum cleaner bag or a vacuum cleaner in which, in particular, the suction effect is less affected as the degree of filling of the bag increases.
  • the invention also raises the problem of disclosing a simple method for producing such a vacuum cleaner bag.
  • the bag acts to reduce the receiving volume with elastic means whose spring force is smaller than the suction force. Due to the interaction of the restoring elasticity force of the bag on the one hand and the suction force acting on it on the other hand, there is also fluttering or hitting the filter material in the dust collecting space, so that the multi-layer nonwoven material of the vacuum cleaner bag is knocked out.
  • the elastic means can be directly in operative connection with the filter material.
  • the filter material may be formed of multiple layers and one of the layers may be elastic.
  • Another embodiment of the direct action of the elastic means may also be that elastic bands are arranged on the filter material. Such a bag is very easy to manufacture.
  • the elastic means is formed of an elastic fabric or net, which cooperates with the filter material.
  • the elastic fabric, mesh or elastic bands may also be attached to the inside of the bag.
  • the elastic fabric or mesh loosely envelops the pouch and thereby does not interfere with the flow of air.
  • the elastic fabric or mesh is also very easy to attach to the support plate.

  • the elastic bands can be secured in the relaxed or slightly tensioned condition, which simplifies manufacturing.
  • the bag has only a small footprint in this state, which simplifies its storage. Also, the insertion of the bag in the lo dust collection chamber of the vacuum cleaner is simplified.
  • At least two further sections are folded onto the side opposite the holding plate before folding the first section transversely to its folding direction.
  • at least one elastic band should be attached to the central region of the first folded portion and to an unfolded portion. In this way, i 5 is ensured that the bag in the unfolded state is surrounded on all sides by elastic bands.
  • the elastic bands are in this state on the side facing away from the plate and therefore do not interfere with the insertion into the receptacle of the vacuum cleaner.
  • the means can also interact with the bag indirectly.
  • means may be provided in the dust collecting space which compress the receiving volume of the bag in a state unfolded in the dust collecting space when the suction air is switched off.
  • the indirect means in the dust collecting space comprise elastic means whose restoring elasticity force 2 5 is less than the suction force acting on the bag.
  • spring elements such as spring-loaded plates, for this purpose can be arranged in isolation in the dust collecting space, which make the volume reduction when the fan is switched off.
  • elastic bands or an elastic fabric or mesh are used, which envelop the bag. These may be attached to a receptacle located in the 30 Staubsammelraum for the holding plate of the bag. The advantage would be that even conventional vacuum cleaner bags can be used, which is not yet involved a direct-acting elasticity.

Likewise, an arrangement of elastic bands, elastic fabric or a lo elastic net on the inside of the vacuum cleaner bag 4 is conceivable.
