PROBLEM TO BE SOLVED: To provide a catalyst converter manufacturing method capable of simply reducing dispersion of compression of a mat. SOLUTION: The outside diameter of a catalyst carrier 1 is measured, a mat 2 is wound around the catalyst carrier 1, the catalyst carrier 1 wound around with the mat 2 is passed through a guide hole 8 in a guide tool 6, and the mat 2 is compressed in advance and inserted in a pipe 4. Next, A die 10 having less dispersion of compression of the mat 2 is selected out of a plurality of dies 10 having taper holes 12 of different sizes according to the measured outside diameter of the catalyst carrier 1, the pipe 4 with the catalyst carrier 1 inserted therein is passed through the tapered hole 12 and the pipe 4 is contracted. After contracting the pipe 4, both ends of the pipe 4 are contracted in a tapered shape. COPYRIGHT: (C)2005,JPO&NCIPI
