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.
