Abstract

According to the present invention, a brake unit is disposed at a side of the forward direction of the fin material from a reforming unit. The brake unit contracts the fin material so that the adjacent folded portions contact with each other while being reformed. Thus, the contracted fin material is in a stable state not to be deformed easily. In this way, even if moment tilting flat portions of corrugated fin is given by the reforming unit, the flat portions are prevented from tilting. A concave or convex deformation of the folded portions can be reformed satisfactorily.
