  • Patent number: 5391338
    Abstract: A process is described for manufacturing a carbon particle filter having a plurality of channels which extend in the exhaust gas flow direction and which are alternatingly sealed at the upstream and downstream end of a porous ceramic material. To minimize the time required for producing the channels, a slip-like ceramic starting material is applied to a fabric having longitudinal threads corresponding to the size location and position of the channels and extending at least in the longitudinal direction of the filter. The carbon filter body is then formed by layering the coated fabric and thereafter in the course of the ceramic firing of the carbon filter body, its inlet and outlet channels are formed by burning away the longitudinal threads.
