Abstract
A metal tape barrier has a generally constant edgewise arcuate curvature and a channel providing a lengthwise bight having a reinforcing wire therein. The tape wraps from about 200.degree. to about 220.degree. of the periphery of the wire, just sufficient to hold the wire in place. Continuous flange regions of the tape extend outwardly of the channel and cooperate with the channel and the reinforcing wire to impart strength to the barrier so that it is self-supporting and is resistant to being collapsed. The tape has barbs formed outwardly of the flange regions and reduced width regions of the flange regions at the roots of the barbs enhance the penetration capabilities of the barbs.
Claims4
A self-supporting barrier structure comprising an elongated metal tape having a generally constant edgewise arcuate curvature therein providing a series of interconnected coils of equal diameter, said tape having a channel formed lengthwise therein and providing a bight, a reinforcing wire disposed in the bight and uniformly gripped by said tape throughout its length, said tape further having continuous reinforcing flange regions extending from opposite sides of said coil channel and barbs formed at spaced intervals along said tape and extending outwardly of the extent of said flange regions, said barbs formed in pairs with the individual barbs in each pair extending in opposite directions and each pair having a root portion connecting the pair to the flange region of the tape, the width of the flange regions of the tape adjacent each barb root being narrower than the wider flange regions elsewhere along the tape.
A self-supporting barrier structure comprising an elongated metal tape having a generally constant edgewise actuate curvature therein providing a series of interconnected coils of equal diameter, said tape having a channel formed lengthwise therein and providing a bight, a reinforcing wire disposed in the bight and uniformly gripped by said tape throughout its length, said tape further having continuous reinforcing flange regions extending from opposite sides of said coil channel and barbs formed at spaced intervals along said tape and extending outwardly of the extent of said flange regions, said reinforcing wire gripped by said tape around from about 200.degree. to 220.degree. of the periphery of the wire, said barbs formed in pairs with the individual barbs in each pair extending in opposite directions and each pair having a root portion connecting the pair to the flange region of the tape, the width of the flange regions of the tape adjacent each barb root being narrower than the wider flange regions elsewhere along the tape.
