Then, the limit is exported the limit with plate of material 33 from coiled material 32 and is sent into metal module 31, repeatedly form simultaneously the operation of a ripple top column 54 and adjacent with this ripple top column 54 wave base section row 55 by processing department 34, thus, form continuously integrated a plurality of ripple plate 51.At this moment, as shown in figure 10, plastic deformations occur in plate of material 33, and the front end of plate of material 33 tilts in the mode with respect to both side edges X at an angle, and parallel with the both side edges of the both side edges of the wave crest section 52 of ripple plate 51 and wave base section 53.
In addition, in part before being admitted to metal module 31, from the front end of plate of material 33 with the interval equal in length of the stagger arrangement fin 50 that should make, with the part of the edge, both sides of the wave crest section 52 of formation ripple top column 54 in the processing department 34 of metal module 31 and form wave base section row 55 wave base section 53 the edge, both sides part X at an angle ground and at a certain at least end, set in advance the slit (diagram summary) of the lateral margin that does not arrive plate of material 33 here at two ends.
Next, after the formation of above-mentioned ripple plate 51 proceeds to part over slit, cut off the part in the outside at the two ends of slit.In addition, the mode that becomes the right angle with both side edges and two ends is cut off from the both ends of plate of material 33 cut parts.Like this, make stagger arrangement fin 50.
In addition, the shape at the two ends of the stagger arrangement fin that cooperation should be made as shown in Figure 7, can also replace slit 36 and be pre-formed leg-of-mutton through hole 40 on plate of material 33.
