Abstract
Flat-plate connecting portions are formed in a band plate by a connecting-portion forming unit. The flat-plate connecting portions are cut off by another connecting-portion forming unit except one flat-plate connecting portion so as to form a corrugated-plate connecting portion. A corrugated-plate portion is formed by a corrugation forming unit, so that the corrugated-plate portion has multiple projections arranged in a width direction of the band plate and each of the projections extends in a plate feeding direction. The corrugated-plate connecting portion corresponding to a predetermined connecting number is cut off so as to form a corrugated fin having a predetermined number of corrugated-plate portions.
