Abstract: This laser irradiation mechanism includes a control unit which has a function allowing the focal point of a laser beam to describe a circle, performs control such that the focal point describes a spiral, and performs control such that the central axis of the spiral moves along a curved surface.

Abstract: A method for assembling a metal honeycomb catalyzer carrier includes the steps of winding corrugated belt plate materials into a substantially cylindrical shape, forming a wound structure into a predetermined cylindrical shape with a die 101 and pushing out a wound honeycomb body 12 obtained through the forming from the die and inserting the wound honeycomb body 12 into the interior of a tubular member 13. An assembling apparatus 31 includes a winding unit 42 which includes, in turn, a rotational holding shaft 167 and a press roller unit 38, a die unit 39 for forming a wound structure wound round the rotational holding shaft 167 into a wound honeycomb body 12 of a predetermined cylindrical shape (of an outside diameter Dp), a tube support unit 132 for setting a tubular member 13 at an edge of a die surface 126, and a honeycomb push-out and insertion unit 34 for pushing out a formed structure from a die 101 and inserting the formed structure so pushed out into the tubular member 13.

Abstract: In a metal honeycomb-shaped catalyzer carrier 11, a corrugated portion 24 is formed on one side 33 in the longitudinal direction of a metallic thin belt plate 23. A plurality of belt plates 23, . . . are alternately stacked such that a flat plate portion 35 on the other side 34 of another belt plate 23 is superimposed on the corrugated portion 24, and are wound from their central flat portion 25 in the longitudinal direction thereby to form a wound honeycomb-shaped carrier body 12. The wound honeycomb carrier body 12 is fit in a hollow cylindrical member 13. The central flat portion 25 of the belt plate is wound so as to form a central cylindrical portion 17 having diameter of D, and length of the central flat portion in the longitudinal is at least 4.14 D.
