Claims

[Claims for Utility Model Registration] (1) In a pair of cutters for forming corrugate fins with louvers that are each formed in the shape of a gear and mesh with each other, the pair of teeth that mesh with each other have a louver molding portion that is equal to the thickness of the louver. A large number of flat plates 2 each having a tooth-shaped blade part 1 formed on the outer periphery are stacked in the axial direction, and each flat plate 2 has a forming blade part on at least one plane in the axial direction. A plating layer 3 is formed, which constitutes a spacer and connects each of the adjacent flat plates 2, 2.
A cutter for forming corrugate fins, characterized in that an extremely small gap is provided between the blade parts 1, 1. (2) The cutter according to claim 1, wherein the plating layer is formed on all sides of the flat plate, and the hardness thereof is smaller than the hardness of the blade portion.
