Abstract (en)

[origin: WO2017098035A1] The present invention relates to methods for establishing an improved integral connection between a retaining plate and the wall of a vacuum-cleaner filter bag. According to a first variant, rather than the retaining plate being applied directly to the wall of the vacuum-cleaner filter bag, a textile material is arranged between the retaining plate and the wall. The retaining plate and the wall of the vacuum-cleaner filter bag are connected in this case via the textile material. According to a second variant, a film made of a thermoplastic material is arranged in certain regions between the retaining plate and wall of the vacuum-cleaner filter bag. The retaining plate and the wall of the vacuum-cleaner filter bag are connected in this case via the film. According to a third variant, the retaining plate is connected directly to the wall of the vacuum-cleaner filter bag. In this case, at least in the region in which the retaining plate is applied, the wall is in the form of a film made of special thermoplastic materials. The present invention likewise relates to vacuum-cleaner filter bags in which the retaining plate is connected integrally to the wall of the vacuum-cleaner filter bag in accordance with the above-mentioned principles.
