  • Particulate filter
    Patent number: 6776815
    Abstract: A particulate filter can be prevented from being damaged. The ashes can be removed from the particulate filter without by burning. A non-woven welding operation for a sealing portion can be simplified. The operability is enhanced by facilitating an insertion of a multi-layer body into a heat resisting container. The number of recycling processes executed when particulate matters such as soot are accumulated on the particulate filter is made as small as possible. A particulate filter 1 comprises an axial core 7 composed of a heat resisting metal, a multi-layer body 3 formed by winding said axial core with a multi-layer member into which a non-woven fabric 11 and a corrugated sheet 13 each composed of a heat resisting metal are tiered, and a heat resisting container 5 charged with said multi-layer body 3.
