Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
158 words
A longitudinally extending arrester tape comprising a woven tape body having main warp threads and weft threads, said tape body being considerably wider than it is thick to have opposed narrow side walls and opposed broad side walls, and in which edge warp threads are superimposed and secured on said opposed narrow side walls in a parallel array substantially covering the narrow side walls and extending in planes substantially parallel with said opposed broad side walls to provide a selvedge for protecting the opposed narrow side walls of the tape body against runway abrasion, and wherein each of said edge warp threads is at a less longitudinal tension than said main warp threads and extends longitudinally in wave formation and is secured to said tape body at longitudinally spaced positions by threads extending in the direction of said weft threads, said longitudinally spaced positions being located solely at the troughs of the waves in each edge warp thread.
Claim 2
Dependent Claim
158 words
A longitudinally extending arrester tape comprising a woven tape body having main warp threads and weft threads, said tape body being considerably wider than it is thick to have opposed narrow side walls and opposed broad side walls, and in which edge warp threads are superimposed and secured on said opposed narrow side walls in a parallel array substantially covering the narrow side walls and extending in planes substantially parallel with said opposed broad side walls to provide a selvedge for protecting the opposed narrow side walls of the tape body against runway abrasion, and wherein each of said edge warp threads is at a less longitudinal tension than said main warp threads and extends longitudinally in wave formation and is secured to said tape body at longitudinally spaced positions by threads extending in the direction of said weft threads, said longitudinally spaced positions being located solely at the troughs of the waves in each edge warp thread.
Claim 3
Dependent Claim
30 words
A longitudinally extending arrester tape according to claim 1 wherein each of said edge warp threads is secured to said tape body at longitudinally spaced positions by said weft threads.
Claim 4
Dependent Claim
50 words
A longitudinally extending arrester tape according to claim 2 wherein each of said edge warp threads extends sequentially and alternately over and under weft threads in its respective narrow side wall and lies on the weft threads which it extends over to be maintained in a substantially constant wave form.
