Definitions
- the invention relates to a filter bag for a vacuum cleaner, consisting of a preferably multi-layer non-woven material, which is composed at least in part of plastic fibers, and a holding plate.
- Filter bags for vacuum cleaners are known from the prior art, which are made entirely or partially from plastic fleeces. These usually consist of several layers of plastic fleece, possibly in combination with a paper layer.
- a holding plate which usually consists of a cardboard / paper material or plastic, is used to insert the filter bag into the vacuum cleaner. It is also known to attach the filter bag to the holding plate by gluing or welding, the ultrasonic welding of plastic nonwovens in combination with a plastic holding plate often being preferred.
- the difficulty in fastening the holding plate lies in the endeavor that the filter bag set up should assume a more or less pronounced spatial shape, while a bag which is folded as flat as possible is required for the known manufacturing possibilities.
- the filter bag which preferably consists of a multi-layer nonwoven material, can be produced in the simplest way on a tubular bag system, the filter bag having a side fold and being welded or glued at the lower end.
- the filter bag can be produced in a known manner by pulling a hose which is pulled from a web which can be composed of several layers and is connected via a welded or glued longitudinal seam. The individual bags are then formed by cutting and welding or gluing a lower edge.
- an automatic handling machine can intervene on this peripheral edge, which opens the bag and places it in an injection molding tool.
- the plastic holding plate is now manufactured in such a way that it forms a bond directly with the upper edge of the filter bag.
- the filter bag can be produced in a simple manner in terms of production technology, and at the same time assumes a pronounced spatial shape.
- a common standard system is used for fastening the bag to the holding plate and for producing the bag. By injecting the holding plate onto the edge of the filter bag, a secure connection is created, whereby exact dimensions, for example overhang dimensions of the holding plate beyond the filter bag, can also be maintained by the selected method.
- the holding plate is attached as a sprue on the filter bag
- the holding plate can also consist of a hard foam, such as. Polyurethane foam.
- the edge region of the filter bag preferably lies in the holding plate body, it being possible for the edge region accommodated in the holding plate to be melted further by appropriate pressure or temperature in order to achieve an intimate connection.
- the arrangement can further be selected such that the edge region of the filter bag passes through the holding plate at least in sections and the associated edge edge of the filter bag is partially aligned with the surface of the holding plate facing away from the bag.
- the end face is extrusion-coated. Accordingly, the edge of the filter bag which is integrated in the holding plate runs at a distance from the surface of the holding plate which faces away from the filter bag. There is also the possibility that the end face continues on one of the flat sides in the holding plate without extrusion coating.
- the holding plate in the plastic injection molding process on the underside, ie facing the filter bag, can be provided with a circumferential collar adapted to the edge area of the filter, the outer area of which is attached to the free edge of the end face of the filter bag edge area in the course of the spraying process.
- the edge region of the filter bag is compressed to a welded seam, for example via pressure and / or temperature ,
- the invention relates to a filter bag according to the features of the preamble of claim 1, here for advantageous further development
- the edge area of the filter bag assigned to the holding plate be encapsulated with a subsequently hardened plastic or rigid foam to form an adapter.
- the holding plate which consists of another material such as cardboard / paper or plastic, is mounted.
- the holding plate can be glued or welded in the adapter.
- the holding plate consists of plastic and is molded onto the adapter.
- the design of a frame for receiving a holding plate has proven to be particularly advantageous in the case of filter bag materials in which a direct injection process would lead to damage to the fragile filter material. It can also be provided here that the filter bag is connected to the adapter by means of the inner and / or outer flat side, it being further proposed that the end face is overmolded. Alternatively, it can also be provided that the end face continues into the adapter without overmolding on one of the flat sides. Finally, it can be provided that the edge region of the filter bag is compressed into a welded seam.

- FIG. 18 shows a representation corresponding to FIG. 17, but with a cast-on adapter and a holding plate molded onto it.
- the filter bag 1 shown in FIG. 1 essentially consists of a dust bag 2 and a holding plate 3 arranged thereon.
- the dust bag 2 shown in an individual illustration in FIG. 3 consists of a multi-layer, for example four-layer non-woven material, which is composed at least in part of plastic fibers. These plastic nonwovens can be constructed, for example, from melt blown, split fiber or bicomponent fibers, which can be thermally, chemically or mechanically crosslinked. The different layers can also lie loosely one above the other or be laminated together.

- the end face 15 of the edge region 6 is spaced apart from a surface 16 of the holding plate 3 opposite the dust bag 2, so that the end face 15 is also encapsulated.
- the attachment of the dust bag 2 to the holding plate 3 can also be carried out such that the edge region 6 of the dust bag 2 passes through the holding plate 3 - at least partially - over the entire edge length, so that the dust bag 2 only has the inner flat side 13 and the outer flat side 14 is connected to the holding plate 3 and the end face 15 is exposed in the plane of the holding plate surface 16 (see FIG. 8).
- a collar 17, which is arranged in accordance with the opening dimension of the dust bag 2 in the region of its edge region 6, can be formed in a corresponding shape on the underside of the holding plate 3, on the end face 18 of which the end face 15 of the bag tel-edge area 6, in particular a compressed hem 7 is attached in the course of the spraying process.
