Abstract

A corrugated fin cutting device includes a pair of worms that restrains a position of a bottom portion of a corrugated fin material that is being continuously conveyed in a conveying direction, and a guide piece that approaches the bottom portion of the fin material that is being restrained by the pair of worms to determine a position of this bottom portion and moves in the conveying direction in synchronization with the fin material. Further, the corrugated fin cutting device includes cutting blades that move with the guide piece in the conveying direction and cut the bottom portion of the fin material that is positioned by the guide piece. The bottom portion of the fin material is cut when the guide piece passes the worms.
