Definitions
- the invention relates to a filter bag for a vacuum cleaner with a hose-like bag and a closed free end area and an opposite, at least partially closed area and a holding plate, the partially closed area being folded to form a bottom.
- Filter bags for vacuum cleaners which have a tubular bag and which, in addition to a closed free end region, have a folded bottom, a so-called block bottom, are known in the prior art. Dust bags of this type are usually produced from a paper material which can be processed on conventional tubular bag systems. In the case of such filter bags, a corresponding holding plate is generally attached to the block bottom, which has an opening through which it closes cleaning air is led. The task of the block bottom is to stabilize the filter bag and form a three-dimensional bag. The block bottom also makes it easier to install the bag in the vacuum cleaner.
- WO 01/03802 AI describes a special non-woven material made of several layers of filter material that are independent of one another. These independent bearings are combined into a filter material with special properties.
- vacuum cleaner bags which are produced with such a nonwoven material are clearly superior to the previously known ones with regard to the performance of the vacuum cleaner.
- DE 100 64 608 AI describes a solution of how a holding plate can be attached to such a bag. After that, a hose-like arrangement of the vacuum cleaner bag is first carried out with the formation of a longitudinal edge fold. This hose-like arrangement is then separated, so that a second end region is created. The opposite free ends of a hose-like arrangement of this type are closed and, after a corresponding opening has been formed, a holding plate is assigned to an end region.
- a special fold is subsequently provided in the area of the vacuum cleaner bag between the area provided with the holding plate and the free end. accepted. The special configuration of transverse folds is intended to stabilize the slack bag.
- EP 1 059 056 AI describes a further solution as to how a holding plate for a bag can be introduced into the filter material.
- two independent layers of the filter material are brought together and welded in the edge areas.
- the welded material is then separated and the two open transverse sides are welded.
- a corresponding hole is punched into the layers one above the other and a reinforcement is placed around the two layers.
- a filter bag made of a nonwoven material which has at least one end region which is comparable in its design with that of a block bottom made of paper material.
- Another object of the invention is to provide a method for producing such a filter bag.
- the vacuum cleaner bag which consists of a nonwoven material, has an at least partially closed end with respect to the free closed end, the latter being folded to form a base.
- the folding according to the present invention is carried out in such a way that layers of the bag material lying one above the other are present in the bottom at least in regions and are at least partially connected to one another. With this configuration, a block bottom-like stabilization of the vacuum cleaner bag is achieved.
- the decisive advantage of the solution according to the invention is to be seen in the fact that the central weld seam and the at least partial connection of the layers folded over one another stabilize them of the floor is reached, which is sufficient to provide a vacuum cleaner bag, which can be provided at any point with a holding plate and which can therefore be easily installed in a vacuum cleaner, even from a flexible material.
- the holding plate can be freely selected with regard to its design.
- the central weld seam is made over the entire width of the bottom. This increases the stability of the bottom formed by the folding.
- the layers lying one above the other, which have been formed by the folding, are preferably connected by welding or gluing. This gluing or welding can be linear. This enables directional reinforcement of the floor.
- the longitudinal sides that is to say those surfaces of the vacuum cleaner bag, are used to introduce the breaks between the closed free end and the at least partially closed end with the base designed according to the invention into the side surfaces thereby clamped, so that folding is possible.
- the fractions can be designed so that they extend, for example, from the respective corners of the floor, if the floor is square, for example square, and are guided to the opposite free end. It is also advantageous if, starting from the central weld seam, a further pre-break is introduced into the bag material. This facilitates the insertion of gussets and increases the surface of the vacuum cleaner bag.
- the pre-breaks introduced into the long sides of the vacuum cleaner bag can serve to further stabilize the bag material.
- a pre-break in the sense of the invention is understood to mean material densifications that are preferably linear.
- the pre-cracks can be introduced by means of a suitable molding tool and / or by welding.
- the filter bag according to the invention also has a pre-break that is parallel to the central weld. This is used to fold the base towards the long side of the filter bag. It is therefore sufficient if there is such a break.
- the distance of the pre-break is chosen so that it corresponds to the width of the bottom, starting from the central weld.
- the bottom is angular, particularly preferably rectangular.
- the fractions are made from the respective short sides of the rectangle to the free, closed end. Another break is from the central weld to the free end.
- the holding plate it is possible according to the present invention either to connect it to the block bottom, as is known from paper filter bags, or to attach the holding plate to the free side surfaces of the vacuum cleaner bag.
- the holding plate is attached to the bottom of the bag, at least partially covering it. Due to the fact that, according to the present invention, the bag is stabilized by the formation of the bottom, the holding plate can also be attached to the inside of the bag. This can be achieved, for example, by simultaneously inserting and connecting the holding plate with the stamp provided for the bottom formation.
- one-piece holding plates can be used as such by the stabilization of the soil. These can also be provided with a locking mechanism.
- the holding plate is constructed as is known per se from the prior art and has at least one through opening which serves to supply the air to be cleaned.
- the holding plate can also be an element, for. B. a slide or a
- the holding plate can be connected to the bottom of the bag using all of the common techniques of the prior art. For this come e.g. sticking or welding in question.
- the holding plate it is also possible for the holding plate to be arranged on the side surfaces of the vacuum cleaner bag.
- the holding plate it is preferred if the holding plate is attached in the vicinity of the floor, since it is through the floor freely spanned interior in the bag for the insertion of a filler neck and an advantageous air duct can be used.
- the holding plates can, as is known per se from the prior art, consist of plastic or cardboard.
- the bag material is preferably to be formed from a multi-layer nonwoven material, as is e.g. is described in WO 01/03802 AI. Reference is therefore expressly made to the disclosure content of this document.
- the invention also includes all other nonwoven materials previously used in the
- the invention further relates to a method for producing a filter bag as described above.
- a tube-like bag with the at least partially closed end region is produced in a first method step.
- This tube-like bag with the at least partially closed end region can be produced in cycles.
- the tubular bag is made by the formation of the tubular material by connecting z. B. the two edges of a layer of the bag material and then a closing of the open area formed thereby is carried out.
- edges of the layers can be connected and the open end closed in cycles. As well continuous joining of the edges of the layers is possible.
- connection of the open end and the closing of the free end of the previously produced filter bag takes place simultaneously.
- the bags can also be separated.
- connection both when forming the hose and when connecting the open end, can be carried out by ultrasonic welding. Thermal welding is also possible.
- the welding is preferably carried out in such a way that the weld seam is guided over the two tracks lying one above the other.
- the formation of the pre-breaks is carried out during step a).
- the pre-cracks are thus introduced into the filter bag by means of suitable shaping tools or also by means of additional weld seams.
- the invention also includes those embodiments in which the introduction of the pre-creases is carried out in a method step before or after method step a).
- the variant described above is preferred, in which the pre-breaks are introduced during process step a).
- the soil is formed in accordance with the ing invention in that a stamp is inserted from the open side into the bag produced according to process step a). This automatically folds in the area of the floor at the closed end. In order to stabilize the base formed thereby, it is then essential that the layers lying one above the other formed by the folding are at least partially connected. This is preferably carried out in such a way that the layers lying one above the other are glued or welded. This results in additional stabilization of the soil. All methods known from the prior art can be used in the methods for connecting the superimposed layers. Gluing or welding should be mentioned here. Clamping of the individual layers can also be carried out. If the layers are connected by means of welding or gluing, it is further preferred if this is done in a linear manner.
- the stamp provided for the bottom formation is used as A boss.
- the anvil can also serve as a sound reflector for a sootrode during ultrasonic welding.
- the anvil can also serve as a support element for the formation of pre-cracks. Furthermore, it can also be used as a support element when punching the filling opening. A reverse procedure is also possible.
- the stamp can also be used as a sonotrode.
- the method according to the invention thus folds the base, which stabilizes the limp material in the base area leads.
- the method according to the invention also opens up the possibility of arranging the holding plate lying inside on the floor.
- the holding plate is inserted with the stamp in one operation and welded / glued to the bag material. According to the present method, it is still necessary for a corresponding opening to be made in the bag at the points at which the holding plate is attached. If the holding plate is arranged directly on the floor, a corresponding opening is made in the floor area.
- This opening can be introduced either in the web which has not yet been formed into a tube or during process step a).
- the filling opening can also be introduced in process step b) or already in the web which has not yet been formed into a tube, ie before process step a).

- any other embodiment is included, in which other connection technologies known from the prior art are applied. Such a thing
- a pre-break 7 This serves to fold over the bottom in the direction of the longitudinal side of the bag 1.
- the distance of the pre-break 7 from the central weld 6 therefore corresponds to the width of the bottom 9, so that a complete folding over of the bottom 9 is possible.
- the filter bag 1 is also closed at its free end 13 by a further weld 15.
- the bottom 9 is stabilized by the folding described above and the connection of the layers and the central weld 6.
- the base 9 has sufficient stability even without an additional holding plate.
- the bottom also has a through opening 16. This through opening 16 can then be provided with a holding plate (not shown), so that the filter bag can then be hung in a corresponding holder in the vacuum cleaner.
- FIG. 3 now shows a further possibility of how the bottom 9 can be folded.
- a gusset 19 and 20 is formed which, as can be seen from the figure, can be folded over in two different directions. This makes it possible to fold the gusset down onto the side surfaces of the filter bag 1 and glue it there (arrow direction a), or else the gusset can be folded back onto the remaining part of the base 9 and glued there as well. Stabilization of the soil 9 is again achieved by this embodiment.
