Abstract
Abstract A strip fabric material such as an aircraft arrester tape includes a loop formed by securing the end of the fabric material to the body of the fabric material by a joint which includes an additional layer having a thickness which has a relationship to the thickness of the strip fabric material itself lying in the range of ratios from 2:1 to 1:2. The additional layer may be of fabric material or of a cementing adhesive and there may be one or more additional layers, particularly when a fabric material is used.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
158 words
A high-strength strip fabric material for aircraft arrester tapes, having a high strength single loop therein, comprising an end of a single thickness of aircraft arrester tape fabric material turned back upon itself and fixedly secured to the body of the fabric material by at least one means selected from the group consisting of stitching and adhesive cement to form a joint, characterized in that the joint includes an additional layer of at least one material selected from the group consisting of fabric material and adhesive cement which is fixedly secured to said end and to said body by said means and located between said end and said body, which gives a greater extension for a given base load than the fabric material in which the loop is formed, the relationship between the thickness of the additional layer and the thickness of the fabric material of the strip being in the range of ratios from 2:1 to 1:2.
Claim 2
Dependent Claim
158 words
A high-strength strip fabric material for aircraft arrester tapes, having a high strength single loop therein, comprising an end of a single thickness of aircraft arrester tape fabric material turned back upon itself and fixedly secured to the body of the fabric material by at least one means selected from the group consisting of stitching and adhesive cement to form a joint, characterized in that the joint includes an additional layer of at least one material selected from the group consisting of fabric material and adhesive cement which is fixedly secured to said end and to said body by said means and located between said end and said body, which gives a greater extension for a given base load than the fabric material in which the loop is formed, the relationship between the thickness of the additional layer and the thickness of the fabric material of the strip being in the range of ratios from 2:1 to 1:2.
Claim 3
Dependent Claim
21 words
A high-strength strip and loop according to claim 1, wherein the additional layer is an additional layer of strip fabric material.
Claim 4
Dependent Claim
66 words
A high-strength strip and loop according to claim 1, wherein the additional layer is an additional layer of strip fabric material which extends over the whole length of the joint and for some distance beyond it in a direction away from the loop, and which is also secured to the body of the strip fabric material on the side of the joint remote from the loop.
Claim 5
Dependent Claim
22 words
A high-strength strip and loop according to claim 2, wherein the additional layer comprises a plurality of additional layers of fabric material.
Claim 6
Dependent Claim
64 words
A high-strength strip and loop according to claim 4, wherein the plurality of additional layers of strip fabric material extend over the whole length of the joint and for some distance beyond it in a direction away from the loop, the additional layers being also secured to the body of the strip fabric material on the side of the joint remote from the loop.
Claim 7
Dependent Claim
40 words
A high-strength strip and loop according to claim 5, wherein that part of the joint between the end and the body of the strip fabric material includes a thickness of each additional layer of fabric material present in the joint.
Claim 8
Dependent Claim
33 words
A high-strength strip and loop according to claim 3, wherein the layers of fabric material to form the joint and the additional layer to form the body beyond the joint are stitched together.
Claim 9
Dependent Claim
37 words
A high-strength strip and loop according to claim 3, wherein the layers of fabric material to form the joint and the additional layer to form the body beyond the joint are secured together with a cementing adhesive.
Claim 10
Dependent Claim
39 words
A high-strength strip and loop according to claim 3, wherein the layers of fabric material to form the joint and the additional layer to form the body beyond the joint are secured together with a cementing adhesive and stitching.
Claim 11
Dependent Claim
43 words
A high-strength strip and loop according to claim 1, wherein the additional layer is a layer of cementing adhesive of a thickness of not less than 150 of an inch, the said layer securing the end to the body of the fabric material.
Claim 12
Dependent Claim
26 words
A high-strength strip and loop according to claim 10, wherein the layer of cementing adhesive extends beyond the joint on the side remote from the loop.
Claim 13
Dependent Claim
40 words
A high-strength strip and loop according to claim 10, wherein the joint includes stitching through the end and the body of the fabric material and through the layer of cementing adhesive which is present between the end and the body.
Claim 14
Dependent Claim
15 words
A high-strength strip and loop according to claim 10, wherein the cementing adhesive comprises polyurethane.
