<p>A waste gas filter for eliminating harmful constituents from waste gases, in particular from the exhaust gases of internal combustion engines, which has a multiplicity of flow channels or flow chambers and gas-permeable walls, comprises a strip of compression-moulded sintered material provided with spacers (5, 14), the strip (3) being spirally wound in a plurality of windings. Spacings between the individual windings are maintained by the spacers (5, 14) in order to form flow channels (12, 13). The strip (3) and, if appropriate, further components (10, 11, 14) of the filter are sintered to form a unit. <IMAGE></p> |
