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.

Abstract translation: 平板连接部分通过连接部分形成单元形成在带板中。 平板连接部分除了一个平板连接部分之外被另一个连接部分形成单元切掉，以形成波纹板连接部分。 波纹板部分由波纹形成单元形成，使得波纹板部分具有在带板的宽度方向上布置的多个突起，并且每个突起沿板馈送方向延伸。 对应于预定连接数的波纹板连接部分被切断，以便形成具有预定数量波纹板部分的波纹状散热片。
