An apparatus compresses a mat against a cylindrical catalyst to provide an exhaust gas cleaning device having the catalyst and the mat wrapped around the catalyst. The apparatus has a base to which first and second rods are movably mounted, and first and second pressers connected to respective ones of the first and second rods. A first drive mechanism moves the first, but not the second, rods to bring the first pressers into contact with first peripheral surface portions of the mat so that second peripheral surface portions of the mat are formed into respective convex portions. A second drive mechanism moves the second rods to bring the second pressers into contact with the convex portions of the mat to compress the convex portions while the first pressers are maintained in pressure contact with the first peripheral surface portions of the mat.
