Embodiment Construction
[0053] figure 1 An embodiment of a filter assembly 1 according to the invention with two cover layers 2 is schematically shown in a perspective view. The cover layer 2 is at least partially made of a porous material (see dashed area) and has two edge regions 3 on opposite sides. Next, the filter module 1 comprises a fiber layer 4 consisting of a fiber fabric. The two covering layers 2 form an outer shell 31 surrounding a fiber layer 4 , so that the fiber layer 4 is arranged integrally inside the two covering layers 2 . The two covering layers 2 are joined to one another (connection 22 ), in particular soldered or welded to one another, in the edge region 3 in the vicinity of an edge 6 .
[0054] The fiber layer 4 has a first length 9 and a first width 10 . The cover layers 2 each have a second length 11 and a second width 12 , wherein in the embodiment shown they each have the same value (same length and same width). In principle, the second length 11 and the second width ...

Abstract
A filter assembly through which a fluid can flow and a method for the production thereof are provided. The filter assembly includes at least one covering layer made of an at least partially porous material with at least one boundary region and includes at least one fiber layer made of a fiber fabric. The at least one covering layer forms a sleeve that encloses the fiber layer so that the fiber layer is permanently disposed inside the at least one covering layer. The filter assembly makes it possible to produce a filter body that can be used, in particular, for cleaning exhaust gases of mobile internal combustion engines.
Description
technical field [0001] The invention relates to a fluid-permeable filter unit or a filter body produced from a filter unit according to the invention for cleaning the exhaust gas flow of an internal combustion engine. Furthermore, the invention specifies a method for producing a filter module. Background technique [0002] Looking at the new license plates in Germany, it can be established that a total of one third of all newly licensed vehicles in 2000 had a diesel engine. Here this portion is traditionally considerably higher than, for example, in France and Austria. This increase in interest in diesel vehicles is attributable, for example, to the lower fuel consumption and currently lower diesel prices, but also to the improved driving properties of such vehicles. Diesel vehicles are also very attractive from an environmental point of view because of their significantly lower CO2 compared to gasoline-powered vehicles. 2 emissions. However, it must also be confirmed th...
