Abstract

PURPOSE:To make a product instrument miniaturized and lightweight by forming a roundness on a slit part by a roller after cutting a slit on a fin material by a cutter and forming a corrugated fin by a roller. CONSTITUTION:A corrugated fin stock 2 is passed through a slit cutter 4 in advance and a fin is sharply sheared by the cutting blade thereof. A roundness is then formed on the slit part by a roller 6 having the roundness corresponding to this slit. Finally the corrugated fin stock 2 is bent in a wavy shape by a gear like roller 8 and the slit part is pushed out in the front and rear directions as well. Due to the cutting blade of the cutter 4 being formed at small intervals the looper pitch of the fin is formed smaller. The heat radiation efficiency of the corrugated fin is thus improved and a product instrument is made miniaturized and lightweight.
