Abstract
Abstract The specification describes a method of making a woven tape of the kind comprising two separate webs which are constituted by warp yarns and weft yarns and which are held together in face-toface relation by binding warp yarns woven into both webs, the said two webs being capable of being parted by breaking the binding yarns, which method comprises securing the two webs together face to face by means of the binding yarns in one portion of the length of the tape and leaving the webs unsecured together in another portion of the length of the tape. The binding yarns conveniently extend continuously through said other portion of the tape and can be disposed between the two webs or woven into one of the webs in said other portion.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
168 words
A method of making a woven energy-absorbing tape comprising two separate continuous webs each of which is constituted by warp yarns and weft yarns woven together continuously along the length of the web and which are held together in face-to-face relation by binding warp yarns, the said two webs being capable of being at least partially parted by the application of forces to adjacent ends of the two webs so as to break the binding yarns without destroying the integrity of the webs while absorbing energy from said forces, which method comprises, over at least one portion of the length of tape, weaving the binding warp yarns into both of the webs by crossing and recrossing repeatedly from one web to the other to secure the webs together and, over at least one other portion of the length of the tape, extending the binding warp yarns along the tape while weaving said two separate webs having said weft yarns and said warp yarns but leaving the webs unsecured.
Claim 2
Independent Claim
168 words
A method of making a woven energy-absorbing tape comprising two separate continuous webs each of which is constituted by warp yarns and weft yarns woven together continuously along the length of the web and which are held together in face-to-face relation by binding warp yarns, the said two webs being capable of being at least partially parted by the application of forces to adjacent ends of the two webs so as to break the binding yarns without destroying the integrity of the webs while absorbing energy from said forces, which method comprises, over at least one portion of the length of tape, weaving the binding warp yarns into both of the webs by crossing and recrossing repeatedly from one web to the other to secure the webs together and, over at least one other portion of the length of the tape, extending the binding warp yarns along the tape while weaving said two separate webs having said weft yarns and said warp yarns but leaving the webs unsecured.
Claim 3
Dependent Claim
33 words
A method as claimed in claim 1, further comprising weaving a plurality of said portions wherein said webs are secured together and an intervening plurality of said portions wherein said webs are unsecured.
Claim 4
Dependent Claim
25 words
A method as claimed in claim 2, wherein the binding yarns extend through said at least one other portion of the length of the tape.
Claim 5
Dependent Claim
30 words
A method as claimed in claim 3, wherein the binding yarns are laid between the two webs in said at least one other portion of the length of the tape.
Claim 6
Dependent Claim
20 words
A method as claimed in claim 4, wherein the binding yarns in said at least one other portion are unwoven.
Claim 7
Dependent Claim
35 words
A method as claimed in claim 3, wherein the binding yarns are disposed among the weft yarns of one of the webs in said at least one other portion of the length of the tape.
Claim 8
Dependent Claim
150 words
A woven energy-absorbing tape comprising two separate webs which extend continuously along the length of the tape and each of which is made up from the warp yarns and weft yarns woven together continuously along the length of the web, and a plurality of binding warp yarns which over a first part of the length of the tape are woven into the two webs and cross and recross repeatedly from one web to the other for holding the two webs together in face-to-face relationship, and which over another part of the length of the tape lie in an unwoven state along the longitudinal direction of the tape, the two webs being capable of being at least partially parted by the application of forces to adjacent ends of the two webs so as to break the binding yarns without destroying the integrity of the webs while absorbing energy from said forces.
Claim 9
Dependent Claim
150 words
A woven energy-absorbing tape comprising two separate webs which extend continuously along the length of the tape and each of which is made up from the warp yarns and weft yarns woven together continuously along the length of the web, and a plurality of binding warp yarns which over a first part of the length of the tape are woven into the two webs and cross and recross repeatedly from one web to the other for holding the two webs together in face-to-face relationship, and which over another part of the length of the tape lie in an unwoven state along the longitudinal direction of the tape, the two webs being capable of being at least partially parted by the application of forces to adjacent ends of the two webs so as to break the binding yarns without destroying the integrity of the webs while absorbing energy from said forces.
Claim 10
Dependent Claim
29 words
A woven energy-absorbing tape as claimed in claim 7, wherein over said another part of the length of said tape said binding warp yarns lie between said two webs.
Claim 11
Dependent Claim
33 words
A woven energy-absorbing tape as claimed in claim 7, wherein over said another part of the length of said tape said binding warp yarns lie among said weft yarns of said two webs.
Claim 12
Dependent Claim
18 words
An energy-absorbing tape as claimed in claim 7 wherein each of the two webs is a tubular web.
