- a dust filter bag in the form of a flat bag with gussets is known from DE 20 2005 000 917 Ul.
- this flat bag consists of an outer wall and a sub-wall congruent to it, wherein the wall material is formed from a flexible, weldable material and is attached to its surrounding wall. along the peripheral edge is welded together.
- the characteristic of this dust filter bag is that on at least one side of the bag to the inside of a folding is provided, which has been realized by one nen formed by the upper wall pleat legs and formed by the lower wall pleat legs.
- this flat bag is thus assumed by two major congruent large upper and lower walls of the flexible material and then made a weld edge.
- the wrinkling is then performed, so that the weld on the side at which the folding occurs, then when the bag is folded, is disposed within the fold. In the operating state, the folding can then be everted.
- the folding be realized on at least one side of the bag of the flat bag in such a way that the folding in one of the two layers is made and the folding can be everted.
- the fold-out is understood in the sense of the invention as meaning also the unfolding of the pleat legs to each other up to the complete outward protrusion of the side pleat.
- the dimensioning is designed in such a way that the larger pleat leg can then be welded to the second layer forming a protrusion on the edge side of the flat bag according to the present invention thus no weld seam is present in the collapsed state in the inner fold Welding takes place at the edge between the peripheral edge of the second layer and the projection of the larger pleat leg of the folded layer.
- different geometries such as trapezoid or triangle can be realized.
- the manufacturing technically difficult Einülprata is avoided for the gussets after welding.
- the folding be designed such that it is ejected substantially over the entire width of the bag side.
- the folding can be designed in such a way that a substantially trapezoidal outer fold is produced in the completely everted state. If the folding is additionally fixed in all marginal areas, then outer folds deviate from the trapezoidal shape.
- a further embodiment of the invention proposes that the fold-out folding be formed in such a way, e.g. by a one-sided fixation that over at least one width of the bag side only partially an outer fold, e.g. in triangular form.
- a corresponding inner fold is present at the same time.
- the dust filter bag according to the invention is preferably selected from its basic shape so that it has a rectangular or square shape.
- a weldable air-permeable material for the individual layers of the flat bag according to the invention is in particular nonwoven material, here also particularly preferably composite materials of nonwoven materials with different filter properties suitable.

- the invention further relates to a method for
- the procedure is such that, in departure from the procedure described in DE 20 2005 000 917 U1, the folding is first carried out and then only then the welding takes place.
- this takes place in that a first web-shaped sub-web is provided with a larger area in relation to a web-shaped top web and that the fold is then introduced into this sub-web.
- 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.
- ultrasonic welding has proven to be suitable as a welding method.
