Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
129 words
A multi-element self-gripping channel device for releasably gripping an opposed article, said device comprising an elongated, flexible web in the form of a flexible plastic strip having parallel longitudinal edges and a plurality of closely-spaced gripping members arranged in rows only along both longitudinal edges of said web, said members having stems extending substantially perpendicularly from at least one face of said web to form said channel, each of said stems having sharp gripping portions formed thereon and arranged to penetrate and grip a surface of said opposed article when said channel device is pressed thereagainst, said gripping portions having gripping surface extending angularly to the axis of said stems, whereby said gripping portions are operative to lodge in said article and grip said article in a self-adhering action.
