  • the cassette sleeve 21 facing the base unit-side blowing nozzle 10 is provided with a circumferential seal 33.
  • the neck closure flap 14 is arranged in the illustrated embodiment, the mouth side of the cassette shell 21, so that this contaminated by the vacuum cleaner flap 14 is replaced in the course of a cassette change with.
  • leg spring 24 acts on the flap 14 in the direction of its closed position.
  • the closure means 28 are in the second embodiment part of the interchangeable cassette 15. These are each designed as semicircular annular elements whose free ring ends are arranged on a common pivot axis y. This pivot axis y extends parallel to the cassette bottom 19, wherein further the annular portion-shaped closure means 28 in an initial position, d. H. are aligned in a non-use position in parallel alignment with the cassette bottom 19 in vertical spacing therefrom.
  • The, the pivot axis y ausformenden, from the free ends of the closure means 28 radially outwardly projecting pivot pin 36 are guided by the cassette wall 18 radially outward for rotationally fixed coupling of the closure means 28 with Hassis beauen operating levers 37 in the cassette operating position.
  • the operating lever 37 are accessible after operation of removing the filter chamber 4 and corresponding exposure of the filter material 11 formed from the optionally filled dust filter bag 5.
  • the annular portion-shaped closure means 28 are pivoted from its ground-parallel position to move under each other of the closure means side annular surfaces.
  • the latter show, as from the detailed representation in Fig. 17 to recognize, in accordance with the first embodiment, electrically contactable metal wires 32, for welding the here preferably the inside wall with a plastic film 47 laminated enforcement section 27.
  • the metal wires 32 are arranged in pairs, so that in the region of each closure two mutually parallel welding zones result, which secure the closure.
  • the electrical contacting of the metal wires 32 is achieved via the outwardly guided pivot pin 36, which are connected in the storage area of the chassis-side operating lever 37 with a device-side power supply, for example in the form of sliding contacts.
  • the closure means 28 further have in the area between the welding zones for creating the bottom closure 24 and the opening closure 31 in opposite directions aligned cutting edges 38, the separation of the opening side sealed dust filter bag 5 from the protruding from the cassette 15, serving to form the next dust filter bag 5 filter material area.
  • the cutting edges 38 of the closure means 28 are provided partially over the circumferential length of the respective closure means 28, so that only a partial penetration of the filter material 11 is made via the cutting edges 38. Accordingly, after formation of the bottom closure 24 and the opening closure 31, a perforation 39 occurs between the closure zones, along which the user can sever the filled and sealed dust filter bag 5 by tearing along the perforation line.
  • Fig. 21 shows a perspective view of a filled, closed on all sides and separated dust filter bag. 5
  • the filter chamber 4 illustrated with reference to the second embodiment has, opposite and in an imaginary extension to the blowing nozzle 10, a chamber outlet channel 40 which is connected in terms of air flow to the vacuum cleaner-side blower unit 3.
  • the nozzle 40 is on the inside covered by a sieve-like retaining element 41st
  • the filter chamber 4 is provided on the inside with a circular cylindrical supporting grid 42, for stabilizing the shape of the filter chamber 4 constructed in the dust filter bag 5.
  • the dust filter bag is rail-guided positional orientation, including the dust filter bag 5, for example in the region of the outer folds 16, for example in the is provided between two spaced-apart outer folds 16 adjusting areas with radially projecting pin 43. These are arranged diametrically opposite and engage in corresponding, perpendicular to the cassette bottom 19 aligned rails 44 of the retaining element 41 (see. Fig. 23 ).
  • the pins 43 are formed in a development as axial, ie transverse to the Faltelungsebene directed ribs, further in one piece and of uniform material formed from the filter material.
  • Fig. 24 shows an alternative solution for closing the bottom or for closing the bag opening.
  • a wrapping of the area to be closed is provided.
  • the wrapping material 45 may be, for example, a yarn or a metal wire, further for example a plastic clip or the like.
  • the bottom closure 24 and / or the opening closure 31 can be produced by a pressure closure 46 (cf. Fig. 25 ).
  • a pressure closure 46 (cf. Fig. 25 ).
  • the facing surfaces have depressions and opposite elevations, which viewed in cross section in the manner of a dovetail connection under pressure (arrows P) are joined together.
  • FIGS. 26 to 29 show two further embodiments of a magazineable, in a cassette 15 to be stocked filter material 11 for forming prefabricated dust filter bag 5 and each one of the filter material 11 by closure and separation from the filter material storage residue separated dust filter bag. 5
  • FIGS. 26 and 27 show an embodiment in which by packaging a substantially circular cylindrical dust filter bag 5 can be produced.
  • the vertical distances of the folds (outer folds 16 and inner folds 1) running transversely to the longitudinal extent of the dust filter bag 5 are uniform and in relation to the vertical distances of the folds in the filter material storage position according to FIG Fig. 26 significantly enlarged.
  • the ratio of inner diameter to outer diameter in the storage position of the filter material 11, ie further the ratio of the diameter of inner folds 17 to outer folds 16 is chosen so large considering the centrally through the filter material supply passing through blast nozzle 10 and the permeating cassette sleeve 21 that a possible thin storage position is achieved, which is favorable to the stockpiling in the cassette 15 effects.
  • the length of a filter material 11 according to Fig. 26 manufactured dust filter bag 5 individually adjustable, since not necessarily predefined closure areas must be formed in the filter material 11.
  • FIGS. 28 and 29 show an embodiment in which the closing and separating regions of the filter material 11 are defined and formed at equal longitudinal intervals of the filter material 11. This is also given by the selected shape of the filter material 11 to be produced from the dust filter bag 5. This is rotationally symmetrical oval or in the form of a sphere formed with diametrically opposed bottom and opening closures 24, 31. This bag shape also requires an alternative reduction in diameter and diameter over the length of the tubular endless filter material, such that the elongated orientation of the continuous filter material a pearl chain-like structuring is recognizable, wherein the diameter-reduced sections define the closure regions.
  • the numerical bandwidths given in each case also include all intermediate values, if not already indicated by way of example anyway, and in particular in 1/10 increments, restricted from the lower and / or upper limit to the respective other limit.
  • "And” stands for the fact that both borders are shifted by one or more tenths to the limit, d. H. be limited.
