Embodiment Construction

[0093] figure 1 A first method according to the invention for producing an inventive wall with inlet openings for a vacuum cleaner filter bag is shown. In the first step, the first step in figure 1 In a) it is shown that the wall 1 of the vacuum cleaner filter bag is provided. The wall can here be, for example, a non-woven material or a film. Likewise, laminates consisting of nonwoven materials or films are conceivable. The material may, for example, be supplied from a roll and unrolled continuously. exist figure 1 In a) (and in all subsequent figures) only a small detail of the material of the wall 1 of the vacuum cleaner filter bag is shown.

[0094] figure 1 b) shows the state after the textile material 2 has been applied to the side of the wall 1 of the vacuum cleaner filter bag by means of four separate individual welding points 3 . The remaining surface of the textile material 2 is loose here and is not connected to the wall of the filter bag. As an alternative t...

Abstract

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 ofthe 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.

Description

technical field [0001] The invention relates to a method for producing an improved material-bonded composite connection of a wall of a vacuum cleaner filter bag to a holding plate. According to a first variant, the holding plate is not applied directly to the wall of the vacuum cleaner filter bag, but a textile material is arranged between the holding plate and the wall. The composite connection of the walls of the vacuum cleaner filter bag and the holding plate is made here by means of a textile material. According to a second variant, a film of thermoplastic material is arranged locally between the wall of the vacuum cleaner filter bag and the holding plate between the wall of the vacuum cleaner filter bag and the holding plate. The composite connection of the walls of the vacuum cleaner filter bag to the holding plate takes place here via the membrane. According to a third variant, the holding plate is connected directly to the wall of the vacuum cleaner filter bag. The ...
