Abstract
Abstract This invention relates to a textile reinforcement for use in the manufacture of rubber or polymer products in which the textile elements running in both lengthwise and generally crosswise directions are not interwoven but held together by a stitching of lightweight construction and bonded by rubber or polymer material. In addition, preferably the principal textile members are ones which include only the normal "producer's" twist rather than the usual twisted cord construction.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
111 words
A fabric structure for use in reinforcing material in polymeric structures comprising a plurality of parallel warp threads and at least one layer of a plurality of parallel weft threads extending transversely at an angle of 75° to 90° to said warp threads and positioned on one side thereof and means stitch-bonding said warp and weft threads into a unitary construction, each of said warp threads being formed of a plurality of continuous filaments and having no more than two twists per inch of length whereby the extensibility of said warp threads is reduced to a minimum, said unitary construction providing increased penetration of the polymetric material into the fabric structure.
Claim 2
Dependent Claim
111 words
A fabric structure for use in reinforcing material in polymeric structures comprising a plurality of parallel warp threads and at least one layer of a plurality of parallel weft threads extending transversely at an angle of 75° to 90° to said warp threads and positioned on one side thereof and means stitch-bonding said warp and weft threads into a unitary construction, each of said warp threads being formed of a plurality of continuous filaments and having no more than two twists per inch of length whereby the extensibility of said warp threads is reduced to a minimum, said unitary construction providing increased penetration of the polymetric material into the fabric structure.
Claim 3
Dependent Claim
53 words
A fabric structure as claimed in claim 1 in which the weft threads extend from one edge of said warp threads to the other with the angle of the threads extending in one direction being the same angle but opposite to the angle of the thread as it extends in the opposite direction.
Claim 4
Dependent Claim
31 words
A fabric structure as claimed in claim 1 in which there are two layers of weft threads with the second layer being formed in a manner similar to the first layer.
