Abstract
A filter or catalyst body comprising wires or fibers is disclosed which is constructed in a single-layer or multi-layer as woven cloth, braiding or knitted fabric, the wires or fibers being at least partially connected to one another by sintering or welding. The woven cloth, netting, braiding or knitted fabric is endowed with inserted powdery, granular or chip-like particles which are sintered with or welded to the wires or fibers to provide a filter density which is lower in the inlet region of the filter body since fewer particles are provided there.
