    摘要： The present invention relates to methods for the production of an improved integral connection of a retaining plate to the wall of a vacuum cleaner filter bag. According to a first variant, the retaining plate is not applied directly on the wall of the vacuum cleaner filter bag but rather a textile material is disposed between retaining plate and the wall. The connection of the retaining plate and the wall of the vacuum cleaner filter bag is thereby effected via the textile material. According to a second variant, in regions between retaining plate and wall of the vacuum cleaner filter bag, a film made of a thermoplastic material is disposed between wall of the vacuum cleaner filter bag and retaining plate. The connection of the retaining plate and the wall of the vacuum cleaner filter bag is thereby effected via the film. According to a third variant, the retaining plate is connected directly to the wall of the vacuum cleaner filter bag. The wall is thereby formed, at least in the region in which the retaining plate is applied, as film made of special thermoplastic materials. The present invention relates likewise to vacuum cleaner filter bags in which the retaining plate is connected integrally to the wall of the vacuum cleaner filter bag according to the preceding principles.

    摘要： The invention relates to a method for optimizing a vacuum cleaning system comprising a substantially hoseless and tubeless vacuum cleaning device and a filter bag, where the substantially hoseless and tubeless vacuum cleaning device comprises a motor-fan unit having a characteristic motor-fan curve, a filter bag receptacle, a connection port for the filter bag and a cleaning head, and where the filter bag comprises filter material made of nonwoven material, comprising the step of: adapting the characteristic motor-fan curve and the size, the shape and the material of the filter bag and the size and the shape of the filter bag receptacle and the inner diameter of the connection port for the filter bag and the cleaning head to each other such that the vacuum cleaning system achieves an efficiency of at least 30%, preferably of at least 34%, particularly preferably of at least 38% when vacuuming according to the Standard on a Standard carpet type Wilton with an empty filter bag, where vacuuming according to the Standard is performed according to Standard EN 60312 and the Standard carpet type Wilton is provided according to Standard EN 60312. The Invention furthermore relates to a vacuum cleaning system having a substantially hoseless and tubeless vacuum cleaning device and a filter bag which is developed and/or manufactured using this method.
