Slow production speeds in the manufacture of lanced and offset fins for use in heat exchanger tubes are eliminated through the use of a method of forming the fins involving a plurality of roll assemblies located along a forming path which may operate on a strip of fin forming material of indeterminate length. After being formed, the fin may be cut to any desired length.
