Abstract
Abstract Strip fastener material comprising a first flexible strip of material having a surface of loose-weave fiber wool, the first strip of material being configured as a narrow strip having a plurality of identical, spaced first projections extending sidewards in one direction therefrom; and, a second flexible strip of material having a surface of resiliently flexible hooks adapted to releasably mate with the wool, the second strip of material being configured as a narrow strip having a plurality of identical, spaced second projections extending sidewards in one direction therefrom, the first projections and the second projections being identical in shape. The material is made by cutting a serpentine path longitudinally through the strips of material to form, in each case, two new strips of material configured as a narrow strip having a plurality of identical spaced projections extending sidewards in one direction therefrom. The fastening material is easily attached to fabric, or the like, by running parallel lines of stitches through the strips and the fabric where one of the lines of stitches is disposed along lines passing through the narrow strips along one side of the strips and the other of the lines of stitches is disposed along lines passing through the tips of the projections.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
181 words
The method of forming and using a strip fastener material comprising the steps of: (a) forming a first flexible strip of material having a surface of loose-weave fiber wool; (b) forming a second flexible strip of material having a surface of resiliently flexible hooks adapted to releasably mate with the loose-weave fiber wool; (c) cutting a serpentine path longitudinally through the first flexible strip of material to form two third strips of material having a surface of loose-weave fiber wool and configured as a narrow strip having a plurality of identical spaced first projections extending sidewards therefrom; (d) cutting a serpentine path longitudinally through the second flexible strip of material to form two fourth strips of material having a surface of resiliently flexible hooks adapted to releasably mate with the loose-weave fiber wool and configured as a narrow strip having a plurality of identical spaced second projections extending sidewards therefrom, the first projections and the second projections being identical in shape; and, (e) using one of the third strips and one of the fourth strips in combination as the fastening material.
Claim 2
Independent Claim
181 words
The method of forming and using a strip fastener material comprising the steps of: (a) forming a first flexible strip of material having a surface of loose-weave fiber wool; (b) forming a second flexible strip of material having a surface of resiliently flexible hooks adapted to releasably mate with the loose-weave fiber wool; (c) cutting a serpentine path longitudinally through the first flexible strip of material to form two third strips of material having a surface of loose-weave fiber wool and configured as a narrow strip having a plurality of identical spaced first projections extending sidewards therefrom; (d) cutting a serpentine path longitudinally through the second flexible strip of material to form two fourth strips of material having a surface of resiliently flexible hooks adapted to releasably mate with the loose-weave fiber wool and configured as a narrow strip having a plurality of identical spaced second projections extending sidewards therefrom, the first projections and the second projections being identical in shape; and, (e) using one of the third strips and one of the fourth strips in combination as the fastening material.
Claim 3
Dependent Claim
66 words
The method of claim 6 wherein the projections of each strip all extend in one direction and step (e) thereof comprises the steps of: (a) attaching one of the third strips to a first surface which is to be releasably fastened to a second surface; and, (b) attaching one of the fourth strips to the second surface with the first projections aligned with the second projections.
Claim 4
Dependent Claim
93 words
The method of claim 2 wherein the first and second surfaces are surfaces of a fabric material and steps (a) and (b) thereof of attaching the third and fourth strips comprise: running parallel lines of stitches through the third and fourth strips and the fabric material where one of the lines of stitches is disposed along lines passing through the narrow strips along one side of the third and fourth strips and the other of the lines of stitches is disposed along lines passing through the tips of the first and second projections.
Claim 5
Dependent Claim
34 words
The method of claim 1 wherein: steps (c) and (d) of cutting serpentine paths comprise cutting along triangular lines which, in each case, are bisected by the center line of the strip being cut.
Claim 6
Dependent Claim
34 words
The method of claim 1 wherein: steps (c) and (d) of cutting serpentine paths comprise cutting along square lines which, in each case, are bisected by the center line of the strip being cut.
Claim 7
Dependent Claim
34 words
The method of claim 1 wherein: steps (c) and (d) of cutting serpentine paths comprise cutting along curved lines which, in each case, are bisected by the center line of the strip being cut.
Claim 8
Dependent Claim
38 words
The method of claim 1 wherein: steps (c) and (d) of cutting serpentine paths comprise cutting along curved lines having semi-circular ends which lines, in each case, are bisected by the center line of the strip being cut.
Claim 9
Dependent Claim
39 words
The method of claim 1 wherein: steps (c) and (d) of cutting serpentine paths comprise, in each case, passing the strip of material between cookie cutter rollers having a blade on one of the rollers defining the serpentine path.
Claim 10
Dependent Claim
172 words
Apparatus for forming a strip fastener material comprising: (a) means for forming a first flexible strip of material having a surface of loose-weave fiber wool; (b) means for forming a second flexible strip of material having a surface of resiliently flexible hooks adapted to releasably mate with said loose-weave fiber wool; (c) means for cutting a serpentine path longitudinally through said first flexible strip of material to form two third strips of material having a surface of said loose-weave fiber wool and configured as a narrow strip having a plurality of identical spaced first projections extending sidewards in one direction therefrom; and, (d) means for cutting a serpentine path longitudinally through said second flexible strip of material to form two fourth strips of material having a surface of said resiliently flexible hooks adapted to releasably mate with said loose-weave fiber wool and configured as a narrow strip having a plurality of identical spaced second projections extending sidewards in one direction therefrom, said first projections and said second projections being identical in shape.
