    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.
