Abstract

A method of making a spacer-expander for a dual rail piston oil ring of the type disclosed in U.S. Pat. No. 3,477,732. The spacer-expander is formed by progressively blanking a strip of flat metal stock to repetitively form successive incremental sections containing two marginal bands, a transverse strut and two legs extending in oppositely offset relation parallel to said strut. The legs are bent to their final inclined relationship with the bands while the strip is still flat. Then the strip is progressively bent into a channel configuration by progressive zone bending of the struts. Further features are set forth in the annexed description.
