Abstract

Self-stacking cooling fins are so designed that they can be made on a continuous basis. Copper alloy strip 31 is fed between a pair of forming rolls 34, 35. During one half revolution of the rolls, openings for tubes and other projec­ tions are pushed out of the strip on one side. During the next half revolution of the rolls, openings for tubes and other projections are pushed out of the strip on the other side. Folds are formed between these sections of strip. The folds cause the strip to fold in zig-zag fashion, and the projections then all point in the same direction and space adjacent fins from each other.
