Abstract
An exhaust gas filter employed to remove harmful components from exhaust gases, more particularly from exhaust gases expelled by combustion engines, includes flow channels or chambers having gas-permeable walls. The walls are formed by a band having compression-moulded material and spacers with the band wound into a spiral. The spacers serve to form flow channels by maintaining a space between the individual windings of the band. The band and, if required, further parts of the proposed filter are then sintered together to form a unit.
