摘要：The inventive particle filter for cleaning exhaust gases of internal combustion engines comprises a filter body (4) consisting of at least one filter belt (18) which is wound around the longitudinal axis (19) of the filter body (4) and radially form interspaced filtering walls (21, 22, 24, 26) which separate a first filtering space (23) situated in the flow direction upstream of said filtering walls (21, 22, 24, 26) from a second filtering space (27) situated downstream thereof, wherein the first filtering space (23) is open on the input side towards the first frontal face (12) of the filter body (4) and is closed on the output side towards the second frontal face thereof. Said invention is characterised in that a radial distance (A) between the radially limited filtering walls (21, 22, 24, 26) of one of the filtering space (23, 27) in the area of one of the frontal faces (12, 13) is greater than the radial distance (a) between the radially limited filtering walls (21, 22, 24, 26) of the other filtering spaces (27, 23).
