Abstract
Abstract A tire cord fabric is disclosed, comprising a plurality of parallel warp threads and a plurality of weft threads interwoven with said warp threads. The weft threads have before dipping of the fabric a length which is longer than the width of the tire cord fabric by approximately the extent of the crimp or shrinkage occuring during dipping. The ends of the weft threads are returned into the fabric before dipping but during dipping such ends are more or less completely drawn out of the fabric due to the shrinkage or increased crimp so that they are finally positioned at the normally woven rims of the tire cord fabric.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
141 words
Tire cord fabric, comprising a plurality of parallel warp threads and a plurality of weft threads interwoven with said warp threads and longitudinally extending between oppositely disposed margins of said fabric and arranged generally perpendicularly to said warp threads, at least part of said weft threads being characterized by adjacent ones thereof being noncontinuous with one another and having a length before impregnating or dipping of said fabric during tire building, that exceeds the width of said fabric by approximately the extent of crimp which occurs to the weft threads during impregnating or dipping processes; wherein both distal ends of said interwoven weft threads are folded back into the tire fabric at the margins of said fabric; whereby the weft threads exert minimal lateral crimping forces on the warp cords at the fabric margins during dipping or impregnating of the fabric.
Claim 2
Dependent Claim
141 words
Tire cord fabric, comprising a plurality of parallel warp threads and a plurality of weft threads interwoven with said warp threads and longitudinally extending between oppositely disposed margins of said fabric and arranged generally perpendicularly to said warp threads, at least part of said weft threads being characterized by adjacent ones thereof being noncontinuous with one another and having a length before impregnating or dipping of said fabric during tire building, that exceeds the width of said fabric by approximately the extent of crimp which occurs to the weft threads during impregnating or dipping processes; wherein both distal ends of said interwoven weft threads are folded back into the tire fabric at the margins of said fabric; whereby the weft threads exert minimal lateral crimping forces on the warp cords at the fabric margins during dipping or impregnating of the fabric.
Claim 3
Dependent Claim
36 words
Tire cord fabric as recited in claim 1, wherein the weft threads which exceed the width of said fabric are about 10 to 15 mm longer at each end thereof than the width of the fabric.
Claim 4
Dependent Claim
38 words
Tire cord fabric as recited in claim 1, wherein the weft threads are continuously inserted into fabric and every second weft is cut in a distance of 10 to 15 mm from the longitudinal rims of the fabric.
