METHOD OF PRODUCING METAL CORE FOR EXHAUST GAS CATALYST |
摘要 |
A method of producing a metal support for an exhaust gas catalyst. The method comprises the steps of: (a) mating respective end portions of flat and corrugated metal strips in such a manner that respective major portions of the strips extend in opposite directions; (b) putting the mated end portions of the strips between two generally flat holding members; (c) winding the major portions of the flat and corrugated metal strips around the holding members overlapping one on another by a predetermined number of times, thereby to produce an oval structure which includes the flat and corrugated metal strips and the holding members; (d) drawing the holding members from the oval structure thereby to provide a semi-processed oval assembly which has two generally flat bores left therein; and (e) pressing the semi-processed oval assembly in a manner to eliminate the bores thereby to provide a tightly wound oval assembly of the flat and corrugated metal strips. |
