    • 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.
    • 一种装置将垫压在圆柱形催化剂上,以提供一种具有催化剂和包裹在催化剂周围的垫的废气净化装置。 该装置具有可移动地安装第一和第二杆的基座,以及连接到第一和第二杆中相应的杆的第一和第二压脚。 第一驱动机构移动第一杆而不是第二杆,以使第一压脚与垫的第一周边表面部接触,使得垫的第二周面部形成为相应的凸部​​。 第二驱动机构移动第二杆以使第二压脚与垫的凸部接触,以压缩凸部,同时第一压脚与垫的第一周面部分保持压力接触。
