Claims

[Scope of utility model registration request]

The teeth are cut in a helical shape on both slopes,
In a corrugated fin forming roll in which a plurality of corrugated fin forming rolls are arranged in parallel, one of the shoulders of the blade on one side extends to either the tooth tip starting point to the tooth tip apex or the tooth bottom starting point to the tooth bottom apex. As the blade is cut and raised, the hem of the shoulder of this extended blade is located either between the tooth tip starting point and the tooth tip top, or between the tooth bottom starting point and the tooth bottom top, and the other shoulder is located near the tooth bottom starting point or at the tooth tip starting point. It extends to the vicinity and is cut up,
The hem of the shoulder of this extended blade is located near the tooth bottom starting end or the tooth tip starting end, and the other side of the blade is
One of the shoulders is extended to the vicinity of the tooth tip starting point and cut up, the hem of the shoulder of this extended blade is located near the tooth tip starting point, and the other shoulder is extended to the vicinity of the tooth bottom starting point and cut. A corrugated fin forming roll characterized in that the hem of the shoulder of the extended blade is located near the starting end of the tooth bottom when the roll is raised.
