    摘要: A filter for treating a particulate containing exhaust gas stream being discharged from an internal combustion engine. The filter includes a compressible bed through which the exhaust gas flows, said bed being comprised of a mass of randomly disposed metallic fibers which define particulate retaining flow passages. The bed is formed with at least one segment being compressed to a greater density than other similar segments whereby to effect a desired gas flow path through the respective bed segments, and a more uniform distribution.
