Definitions

  • the invention relates to a vacuum cleaner filter bag with at least one gusset formed by two pleat legs.
  • Vacuum cleaner filter bags are often made of nonwovens. Due to their excellent dust holding capacity, the vacuum cleaner filter bags made of nonwovens have practically replaced filter bags made of paper. The manufacture of bags made of nonwovens is fundamentally different from the production of paper bags. Commonly used are rectangular flat bags, which are formed from an upper and a lower layer, which are welded circumferentially around. Such filter bags are for example from the EP 0 161 790 , of the EP 0 639 061 , of the EP 1 059 056 or the EP 1 661 500 known.
  • flat bags are used with circumferential weld and evasive side gussets.
  • Such filter bags are for example from the DE 20 2005 000 918 known.
  • Flat bags with gussets are also from the DE 10 2008 006 769 , of the DE 20 2009 012 839 or the DE 10 2006 023 707 known.
  • Block bottom bags In addition to flat bags, occasionally block bottom bags, also called block bottom bags, are used. Block bottom bags made of nonwoven fabric are expensive to manufacture. Block bottom bags are for example from the DE 20 2005 016 309 , of the DE 20 2007 000 198 , of the DE 20 2007 017 064 , of the DE 20 2009 004 433 or the EP 1 677 660 known.

  • the vacuum cleaner filter bag is formed as a tubular bag, the vacuum cleaner filter bag can be made easier and cheaper than known vacuum cleaner filter bag from a circumferentially welded upper and lower layer. In particular, an additional expense for duplicate processing, path control, welding and roll change, which arises during production from two peripherally welded layers omitted.
  • the vacuum cleaner filter bag may comprise a bag wall.
  • the bag wall can be made of a filter material layer, wherein two, in particular opposite, edges of the filter material layer are connected, whereby a tube is formed. By closing the open ends of the tube by transverse welds a tubular bag is obtained. The joining of the edges in the formation of the tube and / or the closing of the open ends of the tube can be done by ultrasonic welding and / or by thermal welding.
  • the gusset may be disposed on one side of the vacuum cleaner filter bag, particularly on one side of the vacuum cleaner filter bag that is not completely formed by a weld.
  • the gusset may correspond to a folding of the vacuum cleaner filter bag, in particular a folding of the bag wall of the vacuum cleaner filter bag.
  • parts of the bag wall of the vacuum cleaner filter bag may be folded into the vacuum cleaner filter bag interior to form two pleat legs.
  • the gusset thus comprises two pleat legs, through the connection of which at least three edges are formed. Two of the edges are each formed by a weld. The edges formed by welding seams may be in particular opposite edges.
  • the pleat legs may correspond to partial surfaces of the bag wall of the vacuum cleaner filter bag, which are arranged in an invaginated state of the side fold between overlapping with other parts of the bag wall or bordered by parts of the bag wall.
  • Parts of the bag wall may form a front wall and a parallel rear wall, wherein at least one side wall between the front wall and the rear wall is formed by the at least one side gusset.
  • the at least one gusset may assume at least two states, namely a collapsed or folded state in which the pleat legs are disposed with the edges of the pleat legs between other parts of the bag wall and an everted or unfolded state in which the pleat legs do not engage the edges of the pleat legs are arranged between other parts of the bag wall.
  • the gusset may also assume a partially everted or unfolded state in which the pleat legs are arranged with the edges of the pleat legs only partially between other parts of the bag wall.
  • the pleat legs of the everted side gusset can form lateral widenings of the front wall and the rear wall.
  • the invaginated state can be used prior to use of the vacuum cleaner filter bag to allow easy insertion of the vacuum cleaner filter bag in a vacuum cleaner.
  • the everted state may be present in a vacuum cleaner during operation of the vacuum cleaner filter bag to increase the available fill volume.
  • only a partially everted condition of the gusset may be present during operation of the vacuum cleaner filter bag.
  • “Ausstüpbar” means that the gusset is designed such that it can be brought from the invaginated in the everting state, in particular by unfolding or evagination of the gusset.

  • the edges formed by welds of the at least one gusset and the respective transverse welds may include an acute angle.
  • the angle can be measured from the respective transverse weld seam in the direction of the vacuum cleaner filter bag interior. If the edges formed by welding seams are not formed in a straight line, the angle between the respective transverse weld seam and a straight line which results from connecting the end points of the edges formed by welding seams can be measured. Alternatively, the angle between the respective transverse weld seam and a middle tangent at the respective edge of the gusset formed by a weld can be measured. As a middle tangent, a tangent may be used at the midpoint between the two endpoints of a weld formed edge.
  • edges formed by welds may be designed to be movable relative to the transverse welds.
  • the edges formed by welds can be movable such that the angle between the edges formed by weld seams and the respective transverse weld seam is variable.
  • the angle between the respective transverse weld seam and the associated edge of the at least one gusset formed by a weld seam is greater than 90 ° and less than 180 °, in particular greater than 100 °, 110 ° or 120 ° and less than 150 °, 160 ° or 170 °.
  • edges of the at least one gusset formed by welds may be straight and / or curved.
  • both edges formed by welding seams may be straight, both curved or one of the two edges straight and the other edge curved.
  • One or both of the edges formed by weld seams may also be partially straight and partially curved.
  • the fact that the edges of the gusset formed by welds can have different shapes or geometries, the unfolded or everted state of the gusset, which is present in the operation of a vacuum cleaner, can be adapted to the available interior of the vacuum cleaner housing.
  • edges formed by welds may have different lengths. As a result, a further adaptation to the available interior of the vacuum cleaner housing is possible.
  • edges of the at least one gusset formed by weld seams may be formed such that they, in particular in the interior of the vacuum cleaner filter bag, not connected to the bag wall and / or welded. However, the edges of the at least one gusset formed by weld seams may each be connected to a transverse weld seam, ie connect to a transverse weld seam.

  • the intermediate side is not formed by a weld, but for example by a fold line.
  • FIG. 2 The side folds 206 formed by welding seams each adjoin one of the transverse weld seams 204 and 205, respectively, and are thus connected at one end to the respective transverse weld seam.
  • the edges 206 formed by weld seams are not connected to the remainder of the bag wall, in particular inside the vacuum cleaner filter bag. As a result, the gussets with the edges formed by welds 206, so completely, be everted.
  • FIG. 3 shows another exemplary vacuum cleaner filter bag schematically in plan view.
  • two side folds 301 and 302 are shown, which are unevenly formed.
  • a first gusset 301 extends deeper into the interior of the bag than a second gusset 302.
  • edges 306 formed by welding seams of the gussets 301 and 302 are formed different from each other.
  • the edges 306 of the first lateral fold 301 formed by welding seams have a different length
  • the edges 306 of the second lateral fold 302 formed by welding seams have a different curved configuration.
  • the edges 306 formed by welds differ Thus, both for a gusset 301, 302 with each other and from the edges formed by welds 306 of the other gussets 301, 302.
  • edges 306 formed by weld seams can also be formed in the same length and / or geometry in one or both side folds 301, 302.
  • the longitudinal weld seam 303 is here illustrated, for example, centered on the vacuum cleaner filter bag, the longitudinal weld seam 303 can also be positioned differently.
  • the longitudinal weld 303 may be positioned in a region of the vacuum cleaner filter bag, particularly in a portion of the bag wall of the vacuum cleaner filter bag which does not form a gusset of the vacuum cleaner filter bag.
  • FIG. 4 illustrates a method of making an exemplary vacuum cleaner filter bag described above.
  • a filter material layer 400 is provided, into which a through hole 411 is initially punched, which forms an inlet opening for the suction air to be cleaned in the finished vacuum cleaner filter bag.
  • a holding plate 412 for arranging the vacuum cleaner filter bag in the vacuum cleaner is applied in the region of the through hole 411.
  • the filter material layer 400 is formed into a tube, wherein opposite edges of the filter material layer 400 are welded by a machine direction longitudinal weld 403.
  • weld lines are formed for later forming edges of the gussets 401 and 402 to be formed.
  • Filter material located in region 413 is then punched out to form weld-formed edges 406 of gussets 401, 402.
  • transverse welds 404 and 405 are welded transversely to the machine direction and the gussets 401 and 402 are folded or inverted.
  • the welding of the longitudinal weld 403 can be done in particular rotationally.
  • the cutouts may also have any other shapes, for example, U-shaped, semicircular, or trapezoidal at any predetermined angles.
  • the shape of the gussets in particular in an everted or unfolded state, can be determined and adapted to the geometry of the construction space of the vacuum cleaner.
  • FIG. 4 indicates the machine direction to which the terms “longitudinal” and “transverse” refer.
  • FIG. 5 Illustratively shows a top view of a vacuum cleaner filter bag having a through hole 511 as an inflow opening and a holding plate 512 arranged in the region of the inflow opening.
  • the vacuum cleaner filter bag has two side folds 501 and 502.
  • the through-hole 511 and the holding plate 512 are shown in the upper half of the vacuum cleaner filter bag.
  • the through-opening 511 and the holding plate 512 may also be positioned at a different location of the vacuum cleaner filter bag, for example, centered.
  • the passage opening can be arranged, for example, so that the air flow or free jet entering through the passage opening 511 strikes the fixed and air-impermeable longitudinal weld seam.
  • the longitudinal weld can be flat (lying) and have a width of, for example, 2 cm.
  • the longitudinal weld can be formed in particular by a plurality of, in particular evenly distributed, welds. As a result, the bag wall of the vacuum cleaner filter bag can be protected from damage.
