  • Patent number: 8029589
    Abstract: A method is provided for connecting a filter medium to a connection element, wherein the filter medium and the connection element are brought into contact with each other and connected to each other by exposure to laser radiation. The connection element may be welded to the end faces of filter folds in strips having a width of 1 mm. The connection element may include a laser light-absorbing layer and a laser light-transparent layer. The filter medium and connection elements may comprise nonwoven fabrics.

  • Patent number: 6193773
    Abstract: A dust filter bag made of a fiber layer laminated together with a paper layer. The fiber layer is made of synthetic polymer fibers and is arranged on the downstream side of the paper layer. To increase the strength of the dust filter bag, the fiber layer contains melted polymer regions and by way of the polymer regions the fiber layer is additionally consolidated within itself and joined to the paper layer. The polymer regions have a welded area of 0.5 to 10% of the surface area, preferably 1 to 3%, thus resulting in sufficient laminate strength with a low pressure drop.
