ABSTRACT:
The present invention provides a method and apparatus for attaching a ring-like part to the outer periphery of a columnar material, as, for example, in the assembling of a catalytic converter. The columnar material is positioned and supported with its axis oriented horizontally. A guide member is supported from the side to position it adjacent to the columnar material on the same axis as the columnar material. The guide member has an outer inclined surface enlarged towards the columnar material. The guide member is then supported in the axial direction and at the same time, has the side support thereof released. The ring-like part is then pushed while guiding it on the outer inclined surface of the guide member to fit it over a portion of the columnar material. The pushing of the ring-like part is released and then the guide member is again supported from the sides, while at the same time, the support thereof from the axial direction is released. Using the disclosed method and apparatus, it is possible to attach the ring-like part to the columnar material without previously passing the ring-like part over the guide member.
