Filter layer for an, in particular conical, honeycomb body for exhaust gas treatment, method for manufacturing the filter layer, honeycomb body and exhaust gas purification device

摘要

A filter layer includes at least partially gas-permeable material having a plurality of segments joined to one another in such a way that the filter layer has non-parallel edges. Inexpensive manufacturing methods for such a filter layer, conical honeycomb bodies having the filter layer and particle-filtering exhaust gas purification apparatuses for motor vehicles, are also provided.
