摘要： A method for forming a folded fin includes at least the following steps: providing a horizontal metallic strip; forming number of pairs of indents alternately in a top face and a bottom face of the strip; clamping the strip with three folding tools, wherein a first tool is located between a first pair of indents in the top face of the strip, a second tool is located between a successive second pair of indents in the bottom face of the strip and a third tool is located between a fuirther successive third pair of indents in the top face of the strip; and moving the second and third tools toward the first tool to a position where parts of the strip between the first and second tools and between the second and third tools are bent to be vertical, wherein the third tool moves horizontally toward the first tool and the second tool moves at an angle toward an upper side of the first tool.
