Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 115 words
The method of producing a light reflective strip for bicycle wheels comprising, providing an elongated strip of relatively thin light-weight malleable material, corrugating said strip of material to produce alternate ridges and valleys of substantial depth therein, at least partially flattening the corrugations along only one marginal edge portion of the strip to reduce the depth of said ridges and valleys along said one marginal edge portion thereof and thus increase the length of that edge portion as compared with the other marginal edge of said corrugated stip and produce a curved strip wherein the flattened portions form the larger radius of curvature thereof, and applying light reflective material to the surfaces of said strip.
Claim 2
Independent Claim 115 words
The method of producing a light reflective strip for bicycle wheels comprising, providing an elongated strip of relatively thin light-weight malleable material, corrugating said strip of material to produce alternate ridges and valleys of substantial depth therein, at least partially flattening the corrugations along only one marginal edge portion of the strip to reduce the depth of said ridges and valleys along said one marginal edge portion thereof and thus increase the length of that edge portion as compared with the other marginal edge of said corrugated stip and produce a curved strip wherein the flattened portions form the larger radius of curvature thereof, and applying light reflective material to the surfaces of said strip.
Claim 3
Dependent Claim 19 words
The method set forth in claim 1 wherein said light reflective material is applied prior to corrugating said strip.
Claim 4
Dependent Claim 43 words
The method set forth in claim 1 wherein the flattening of the corrugations along one edge of the strip is produced by providing a pair of closely spaced opposed rollers and moving said edge of the strip through the space between the rollers.
